Engine Overheating You will find a coolant temperature gage on your Chevrolet’s instrument panel. You may also find a LOW COOLANT warning light on your Chevrolet’s instrument panel. If Steam Is Coming From Your Engine
5-14 ..
A C*.UTIC i:
Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before opening the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.
I NOTICE:
If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty.

If No Steam Is Ci If you get the overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you:
Climb a long hill on a hot day. Stop after high-speed driving, Idle for long periods in traffic.
0 Tow a trailer. 11 you get the overheat warning with no sign of steam, try this for a minute or so: 1. If you have an air conditioner, turn it off. 2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while driving -- AUTOMATIC OVERDRIVE (@) or DRIVE (D) for automatic transmissions.
If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning doesn’t come back on, you can drive normally. If the warning continues, pull over, stop, and park your vehicle right away.
If there’s still no sign of steam, you can idle the engine for two or three minutes while you’re parked, to see if the warning stops. But then, if you still have the warning, turn 08 the engine and get everyone out of the vehicle until it cools down. You may decide not to lift the hood but to get service help right away.
V8 Engine
When you decides it’s safe to lift the hood, here’s what you’ll see: 1. Coolant Recovery Tank 2. Radiator Pressure Cap 3. Electric Engine Fan
/d CAUTION:
An electric fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling, don’t do anything else until it cools down.
V6 Engine
5-16
When it is cool, remove the coolant recovery tank cap and look at the dipstick. The coolant level should be FULL COLD. If it isn’t, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.
Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine without coolant isn’t covered by your warranty.
~~~
If there seems to be no leak, with the engine on, check to see if the electric engine fan is running. If the engine is overheating, the fan should be running. If it isn’t, your vehicle needs service.

A How to Add Coolant to the Coolant
Recovery Tank If you haven’t found a problem yet, but the coolant level isn’t at FULL COLD, add a 50/50 mixture of clean water (preferably distilled) and DEX-COOL (orange-colored, silicate-free) antifreeze at the coolant recovery tank. (See “Engine Coolant” in the Index for more
information.)
’
A CAUTION:
Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Your vehicle’s coolant warning system is set for the proper coolant mix. With
CAUTION: (Continued)
- - -
plain water or the wrong mix, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mix of clean water and DEX-COOL TM antifreeze.
NOTICE:
In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant and the proper coolant mix.
5-18

YOU can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at FULL COLD, start your vehicle. If the overheat warning continues, there’s one more thing you can try. You can add the proper coolant mix directly to the radiator, but be sure the cooling system is cool before you do it.
5-19
Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the radiator
pressure cap -- even a little -- they can come out
at high speed. Never turn the cap when the cooling system, including the radiator pressure cap, is hot. Wait for the cooling system and radiator pressure cap to cool if you ever have to turn the pressure cap.

How to Add Coolant to the Radiator (V8 Engine Only)
NOTICE:
The LTl Engine (Code P) has a specific radiator fill procedure. Failure to follow this procedure could cause your engine to overheat and be severely damaged.
1. You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise until it first stops. (Don’t press down while turning the pressure cap.) If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.
2. Then keep turning the pressure cap, but now push

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.
4. Fill with the proper mix. Add coolant until you see a
steady stream of coolant coming from the bleed valves.
5. Close the bleed valves. 6. Continue to fill the radiator up to the base of the
filler neck.
7. Rinse or wipe the spilled coolant from the engine
and compartment.
8. Start the engine and allow it to run in idle for approximately four minutes. By this time, the coolant level inside the radiator will be lower. Add more of the proper mix through the filler neck until the level reaches the base of the filler neck.

If a Tire Goes Flat It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you. should ever have a “blowout,” here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop -- well off the road if possible. If a tire goes flat, the next part shows how to use your jacking equipment to change a flat tire safely.
Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard
warning flashers. A CAUTION:
Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving:
1. Set the parking brake firmly. 2. Put an automatic transmission shift lever in PARK (P), or shift a manual transmission to FIRST (1) or REVERSE (R).
3. B r n off the engine.
To be even more certain the vehicle won’t move, you can put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire on the other side of the vehicle, at the opposite end.
5-27
Removing the Spare Tire and T G , , ~ ~
The following steps will tell you how to use the jack and change a tire.
The equipment you’ll need is in the right (passenger) rear area behind the trim panel. First you must remove the close-out panel. See “Close-Out Panel” in the Index. Find the plastic screw heads in the trim panel over the spare tire. Use a coin or a key to turn the screw heads until the slots point front and back to the unlock position. Gently lift the trim panel front forward edge and move it out of the way.
5-28 -
Remove the wing nut and adapter and pull out the spare. See “Compact Spare Tire” later in this section for more information about the compact spare.
To remove the jack and wheel wrench, loosen and remove the bolt and remove the plastic cover.
‘)t
5-29
A
The tools you'll be using include the jack (A) and wheel wrench (B).
The jack has a bolt at the end. Attach the wheel wrench to the jack bolt. Turn the wheel wrench to the right to raise the lift head a little.
5-30
If your wheel has a center cap, pry it off using the wheel wrench.
If your vehicle has a bolt-on wheel cover, loosen the plastic caps using the wheel wrench and remove the wheel cover.
5-31
Removing the Flat Tire and Installing the Spare Tire 1. Using the wheel wrench, loosen all the wheel nuts.
Don’t remove them yet.
If your vehicle has optional alloy wheels, each wheel may have one locknut in place of the standard wheel nut. A special wheel lock key (removal tool) and instructions are located in the center console. Attach the wheel lock key to the socket of the wheel wrench. Remove the locking wheel nut by turning counterclockwise.
5-32
2. Position the jack under the vehicle. There is a notch
in the vehicle’s rocker flange. Raise the jack head until it fits firmly into the notch nearest the flat tire. On convertible models, place the jack in a similar location.
Stay away from the moldings or fender flanges to avoid damaging them. Put the compact spare tire near you.
Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.
NOTICE:
Raising your vehicle with the jack improperly positioned will damage the vehicle or may allow the vehicle to fall off the jack. Be sure to fit the jack lift head into the proper location before raising your vehicle.
5-33
4. Remove any rust or dirt
from the wheel bolts, mounting surfaces and spare wheel.
3. Raise the vehicle by rotating the wheel wrench clockwise. Raise the vehicle far enough off the ground so there is enough room for the spare tire to fit. Remove all the wheel nuts and take off the flat tire.
5-34
Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off.
A CAUTION:
Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident.
Replace the wheel nuts with the rounded end of the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub.
5-35
Tighten the wheel nuts firmly in a criss-cross sequence as shown.
5. Lower the vehicle by rotating the wheel wrench
counterclockwise. Lower the jack completely.
1 Incorrect wheel nuts or improperly tightened ~ wheel nuts can cause the wheel to become loose
and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to 100 lb-ft (140 Nom).
5-36
I NOTICE:’
Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification.
Don’t try to put a wheel cover on your compact spare t’re. It won’t fit. Store the wheel cover in the rear area u til you have the flat tire repaired or replaced.
I NOTICE:
Wheel covers won’t fit on your compact spare. If you try to put a wheel cover on your compact spare, you could damage the cover or the spare.
Storing a Flat or Spare Tire and Tools
Storing a jack, a tire or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

Compact Spare Tire Although the compact spare tire was fully inflated when your vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inflated. The compact spare is made to perform well at posted speed limits for distances up to 3,000 miles (5 000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again. When the compact spare is on the rear axle, the optional ASR system will cycle and limit acceleration for about the first 15 seconds of driving after each engine start.
I NOTICE:
~~
~~~
~~~
When the compact spare is installed, don’t take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle.
NOTICE:
If the compact spare is used as a rear tire, do not drive faster than 50 mph (80 km/h). Damage to the rear axle may occur if the compact spare is driven faster than 50 mph (80 kmk). This speed limitation does not apply when the compact spare is used as a front tire.
5-39
Don’t use your compact spare on other vehicles. And don’t mix your compact spare tire or wheel with other wheels or tires. They won’t fit. Keep your spare tire and its wheel together.
NOTICE:
Tire chains won’t fit your compact spare. Using them can damage your vehicle and can damage the chains too. Don’t use tire chains on your compact spare.
If You’re Stuck: In Sand, Mud, Ice or Snow What you don’t want to do when your vehicle is stuck is to spin your wheels too fast. The method known as “rocking” can help you get out when you’re stuck, but you must use caution.
A CAUTION:
If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transmission or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you’re stuck, spin the wheels as little as possible. Don’t spin the wheels above 35 mph (55 km/h) as shown on the speedometer.
5-40
NOTICE: r Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels too fast while shifting your transmission back and forth, you can destroy your transmission.
~~
For information about using tire chains on your vehicle, see “Tire Chains” in the Index.
Rocking Your Vehicle to Get it Out First, turn your steering wheel left and right. That will clear the area around your front wheels. If your vehicle has ASR, you should turn the system off. (See “ASR System” in the Index.) Then shift back and forth between REVERSE (R) and a forward gear (or with a manual transmission, between FIRST (1) or SECOND (2) and REVERSE (R)), spinning the wheels as little as possible. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. If that doesn’t get you out after a few tries, you may need to be towed out. If you do need to be towed out, see “Towing Your Vehicle” in the Index.

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper Chevrolet Service Manual. It tells you much more about how to service your Chevrolet than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index. Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air Bag-Equipped Chevrolet” in the Index. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index.

You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. Be sure you have sufficient knowledge, experience, and the proper replacement parts and tools before you attempt any vehicle maintenance task. Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.
The 8th digit of your vehicle identification number (VIN) shows the code letter for your engine. You will find the VIN at the top left of your instrument panel. (See “Vehicle Identification Number” in the Index.) If you don’t have the 5.7L Code P engine, use regular unleaded gasoline rated at 87 octane or higher. If you have the 5.7L Code P engine, use premium unleaded gasoline rated at 91 octane or higher for best performance. You may use middle grade or regular unleaded gasolines, but your vehicle may not accelerate as well. At a minimum, the gasoline you use should meet specifications ASTM D4814 in the United States and CGSB 3.5-M93 in Canada. Improved gasoline specifications have been developed by the American Automobile Manufacturers Association (AAMA) for better vehicle performance and engine protection. Gasolines meeting the AAMA specification could provide improved driveability and emission control system protection compared to other gasolines.
Be sure the posted octane for premium is at least 91 (at least 89 for middle grade and 87 for regular). If the octane is less than 87, you may get a heavy knocking noise when you drive. If it’s bad enough, it can damage your engine. If you’re using fuel rated at the recommended octane or higher and you still hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal, and you don’t have to buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem. If your vehicle is certified to meet California Emission Standards (indicated on the underhood tune-up label), it is designed to operate on fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on and/or your vehicle may fail a smog-check test. If this occurs, return to your authorized Chevrolet dealer for diagnosis to determine the cause of failure. In the event it is determined that the cause of the condition is the type of fuels used, repairs may not be covered by your warranty.

Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving. You can also write us at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN).

In Canada, some gasolines contain an octane enhancing additive called MMT. If such fuels are used, your emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may also turn on. If this occurs, return to your authorized Chevrolet dealer for service. To provide cleaner air, all gasolines are now required to contain additives that will help prevent deposits from forming in your engine and fuel system, allowing your emission control system to function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to help clean the air. General Motors recommends that you use these gasolines if they comply with the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that contains methanol. Don’t use it. It can corrode metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t be covered under your warranty.

Filling Your Tank
A CAUTION-
The cap is behind a hinged door on the left side of your vehicle.
Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames, and smoking materials away from gasoline.
To take off the cap, turn it slowly to the left (counterclockwise).
I A , - . _ _ _ _ _ N:
If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel filler cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel filler cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way.
6-5
Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Chevrolet” in the Index. When you put the cap back on, turn it to the right until you hear at least three clicks. Make sure you fully install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See “Malfunction Indicator Lamp” in the Index.
Checking Things Under the Hood
I A CAUTIC 1: An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing and tools away from any underhood electric fan.
NOTICE:
If you need a new cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit and your fuel tank and emissions system might be damaged.

When to Add Oil If the oil is at or below the ADD line, then you’ll need to add some oil. But you must use the right kind. This part explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index.
What Kind of Oil to Use Oils recommended for your vehicle can be identified by looking for the “Starburst” symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this Starburst symbol.
I NOTICE:
Don’t add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged.
The oil fill cap is located on the valve cover near the oil dipstick. Just fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through.
If you change your own oil, be sure you use oil that has the Starburst symbol on the front of the oil container. If you have your oil changed for you, be sure the oil put into your engine is American Petroleum Institute certified for I gasoline engines.

Engine Oil Additives Don’t add anything to your oil. Your Chevrolet dealer is ready to advise if you think something should be added. When to Change Engine Oil See if any one of these is true for you:
Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such as frequent driving in stop-and-go traffic). Most trips are through dusty areas. You frequently tow a trailer or use a carrier on top of your car. The vehicle is used for delivery service, police, taxi or other commercial application.
Driving under these conditions causes engine oil to break down sooner. If any one of these is true for your vehicle, then you need to change your oil and filter every 3,000 miles (5 000 km) or 3 months -- whichever occurs first.
If none of them is true, change the oil and filter every 7,500 miles (12 500 km) or 12 months -- whichever occurs first. Driving a vehicle with a fully warmed engine under highway conditions causes engine oil to break down slower. What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. (See the manufacturer’s warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your dsed oil, ask your dealer, a service station or a local recycling center for help.

Air Clt
3800 L36 (Code K)
5.7L LT1 (Code P)
Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Index.
Operating the engine with the air cleaner off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there, and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner off.
NOTICE:
If the air cleaner is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner in place when you’re driving.
Air Filter Replacement To remove the air filter:
1. Remove the two plastic pins by pulling them
straight up.

2. Disconnect the plastic clamp on the duct. Pull apart
the connection.
3. Pull the air cleaner straight up. Unclamp the metal clips.

4. Open the air cleaner and remove the filter.
Automatic Transmission Fluid When to Check and Change A good time to check your automatic level is when the engine oil is changed. Change both the fluid and filter every 15,000 miles (25 000 km) if the vehicle is mainly driven under one or more of these conditions:
transmission fluid
In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher. In hilly or mountainous terrain. When doing frequent trailer towing. Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these conditions, change the fluid and filter at 100,000 miles (166 000 km). See “Scheduled Maintenance Services” in the Index.
6-19
How to Check Because this operation can be a little difficult, you may choose to have this done at your Chevrolet dealership Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transmission fluid.
Wait at least 30 minutes before checking the transmission fluid level if you have been driving:
When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while. 0 In heavy traffic -- especially in hot weather. e While pulling a trailer.
6-20
To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93°C). Checking Transmission Fluid Hot Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it's colder than 50°F (lO"C), drive the vehicle in DRIVE (D) until the engine temperature gage moves and then remains steady for 10 minutes. Then follow the hot check procedures.
Checking Transmission Fluid Cold A cold check is made after the vehicle has been sitting for eight hours or more with the engine off and is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50°F (10°C) or more. If it's colder than 50°F (IOOC), you may have to idle the engine longer. Should the fluid level be low during a cold check, you must perform a hot check before adding fluid. This will give you a more accurate reading of the fluid level.
Checking the Fluid Hot or Cold
Park your vehicle on a level place. Keep the engine running. With the parking brake applied, place the shift lever in PARK (P). With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in PARK (P). Let the engine run at idle for three minutes or more.
Then, without shutting off the engine, follow these steps:

The transaxle fluid handle is the red loop near the back of the engine. 1 , Pull out the dipstick and wipe it with a clean rag or
paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.
6-22
3800 L36 Engine Transmission Dipstick
3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area for a cold check or in the HOT area or cross-hatched area for a hot check.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.
How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. Add fluid only after checking the transmission fluid HOT. (A COLD check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn’t take much fluid, generally less than a pint (0.5 L). Don ’t overfill. We recommend you use only fluid labeled DEXRON@-111, because fluid with that label is made especially for your automatic transmission. Damage caused by fluid other than DEXRON-I11 is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to Check.” When the correct fluid level is obtained, push the dipstick back in all the way.
6-23
Manual Transmission Fluid When to Check A good time to have it checked is when the engine oil is changed. However, the fluid in your manual transmission doesn’t require changing. How to Check Because this operation can be difficult, you may choose to have this done at your Chevrolet dealership Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading.
NOTICE:
Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transmission fluid.
Check the fluid level only when your engine is off, the vehicle is parked on a level place and the transmission is cool enough for you to rest your fingers on the transmission case. Then, follow these steps: 1. Remove the filler plug. 2. Check that the lubricant level is up to the bottom of
the filler plug hole.
3. If the fluid level is good, install the plug and be sure
it is fully seated. If the fluid level is low, add more fluid as described in the next steps.
How to Add Fluid Here’s how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. 1. Remove the filler plug. 2. Add fluid at the filler plug hole. Add only enough fluid to bring the fluid level up to the bottom of the filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid. It isn’t a good idea to “top off’ your clutch fluid. Adding fluid won’t correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

What to Use Standard Differential Use Axle Lubricant (GM Part No. 1052271) or SAE 80W-90 GL-5 gear lubricant. Limited-Slip Differential To add lubricant when the level is low, use Axle Lubricant (GM Part No. 12345977). To completely refill after draining, add 2 ounces (59 ml) of Limited-Slip Differential Lubricant Additive (GM Part No. 1052358). Then fill to the bottom of the filler plug hole with Axle Lubricant (GM Part No. 12345977). Engine Coolant The cooling system in your vehicle is filled with new DEX-COOL TM (orange-colored, silicate-free) engine coolant. This coolant is designed to remain in your vehicle for 5 years or 100,000 miles (166 000 km), whichever occurs first. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating or if you need to add coolant to your radiator, see “Engine Overheating” in the Index.
A 50/50 mixture of water and the proper coolant for your Chevrolet will:
Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use DEX-COOL (orange-colored, silicate-free) coolant meeting GM Specification 6277M. If silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine
coolant will require change sooner -- at
30,000 miles (50 000 km) or 24 months, whichever occurs first.
6-26
What to Use Use a mixture of one-half clean water (preferably distilled) and one-half DEX-COOL TM (orange-colored, silicate-free) antifreeze that meets GM Specification 6277M, which won’t damage aluminum parts. Use GM Engine Coolant Supplement (sealer) (GM Part No. 3634621) with any complete coolant change. If you use this mixture, you don’t need to add anything else.
Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Your vehicle’s coolant warning system is set for the proper coolant mix. With plain water or the wrong mix, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mix of clean water and DEX-COOL TM (orange-colored, silicate-free) antifreeze.
NOTICE:
If you use an improper coolant mix, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mix can freeze and crack the engine, radiator, heater core and other parts.
If you have to add coolant more than four times a year, have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system. These can be harmful.

5.7L LTl Engine Only
e Recovery Tank
Adding Coolant to If you need more coolant, add the proper mix at the coolant recovery tank, but only when your engine is cool. If the tank is very low or empty, also add coolant to the radiator. See “Engine Overheating” in the Index for information.
When your engine is cold, check the dipstick on the cap of the coolant recovery tank. The coolant level should be at COLD, or a little higher. When your engine is warm, the level on the dipstick should be up to HOT, or a little higher.
6-28
Turning the radiator pressure cap when the engine and radiator are hot can allow steam badly. Never turn the pressure cap -- even a and scalding liquids to blow out and burn you little -- when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not to spill it.
' 4 CAUTIOh;
You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don't spill coolant on a hot engine.
Radiator Pressure Cap (All Engines)
NOTICE:
~~
Your radiator cap is an 18 psi (124 kPa) pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Be sure the arrows on the cap line up with the overflow tube on the radiator filler neck.
When you replace your radiator pressure cap, an AC@ cap is recommended.
6-29
Thermostat Engine coolant temperature is controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a preset temperature. When you replace your thermostat, an AC@ thermostat is recommended. Power Steering Fluid
When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

How To Check Power Steering Fluid When the engine compartment is cool, unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick.
What to Use Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing.
When the engine compartment is hot, the level should be at the H or HOT mark. When the engine compartment is cool, the level should be at the C or FULL COLD mark.
6-31
I Adding Washer Fluid
Open the cap labeled WASHER FLUID OmY. Add washer fluid until the tank is full.
6-32
NOTICE:
When using concentrated washer fluid, follow the manufacturer’s instructions for adding water. Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid. Fill your washer fluid tank only three-quarters full when it’s very cold. This allows for expansion, which could damage the tank if it is completely full. Don’t use radiator antifreeze in your windshield washer. It can damage your washer system and paint.
Brakes Brake Fluid
Your brake master cylinder reservoir is here. It is filled with DOT-3 brake fluid. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is
leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work ‘at all. So, it isn’t a good idea to “top off’ your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.
If you have too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to check your brake fluid. See “Periodic Maintenance Inspections’’ in the Index.
6-33
What to Add When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme 11 No. 1052535). Use new brake fluid from a sealed container only, and always clean the brake fluid reservoir cap before removing it.
(GM Part
cAU' 1u
With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake fluid.
Checking Brake Fluid
You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above the plastic seam in the reservoir. If it isn't, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is above the plastic seam, near the base of
, the filler neck.
6-34
NOTICE:
Using the wrong fluid can badly damage brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid. If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.
Brake Wear Unless you have the four-wheel disc brake option, your Chevrolet has front disc brakes and rear drum brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing o he brake pedal firmly).
The brake wear warning sound means that sooner or later your brakes won’t work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads could result in costly brake repair.
6-35
Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. If you have rear drum brakes, they don’t have wear indicators, but if you ever hear a rear brake rubbing noise, have the rear brake linings inspected. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brakes replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel, This could be a sign of brake trouble. Brake Adjustment Every time you make a moderate brake stop, your disc brakes adjust for wear. If you rarely make a moderate or heavier stop, then your brakes might not adjust correctly.
6-36
If you drive in that way, then -- very carefully -- make a few moderate brake stops about every 1,000 miles (1 600 km), so your brakes will adjust properly. If your brake pedal goes down farther than normal, your rear drum brakes may need adjustment. Adjust them by backing up and firmly applying the brakes a few times. Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Vehicles we design and test have top-quality GM brake parts in them, as your Chevrolet does when it is new. When you replace parts of your braking system -- for example, when your brake linings wear down and you have to have new ones put in -- be sure you get new genuine GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change -- for the worse. The braking performance you’ve come to expect can change in many other ways someone puts in the wrong replacement brake parts.

Battery Every new Chevrolet has a Delco Freedom’ battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedom battery. Get one that has the replacement number shown on the original battery’s label. Vehicle Storage If you’re not going to drive your vehicle for 25 days or more, take off the black, negative (-) cable from the battery, This will help keep your battery from running down.
Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting” in the Index for tips on working around a battery without getting hurt.
Contact your dealer to learn how to prepare your vehicle for longer storage periods. Also, for your audio system, see “Theft-Deterrent Feature” in the Index.
Bulb Replacement For the proper type of replacement bulb, see “Replacement Bulbs” in the Index. Halogen Bulbs
Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured. Take special care when handling and disposing of halogen bulbs.
Headlamps Before replacing a headlamp that does not light, check to make sure that the wiring connector is securely fastened to it. See “Replacement Bulbs” in the Index to check the size and type of headlamp you need to use before you begin to replace the headlamp. You must replace a headlamp with one that is exactly the same. Be careful not to move the aiming screws when you replace the headlamp. If the headlamp being replaced was properly aimed, the new one will be also if it is properly installed.

Headlamp Aiming Your vehicle has the 55 x 135 mini-quad headlamp system. These headlamps have horizontal and vertical aim indicators. The aim has been pre-set at the factory and should need no further adjustment. If your vehicle is damaged in an accident and the headlamp aim seems to be affected, see your Chevrolet dealer. Headlamps on damaged vehicles may require recalibration of the horizontal aim by your Chevrolet dealer. To check the aim, the vehicle should be properly prepared as follows: 0 The vehicle must have all four tires on a perfectly
level surface.
0 The vehicle should not have any snow, ice or mud
attached to it.
0 There should not be any cargo or loading of the
vehicle, except it should have a full tank of gas and one person or 160 lbs. (75 kg) on the driver’s seat.
0 Tires should be properly inflated. 0 . The horizontal indicator should read “0.”
9. Check the headlamp aim indicators. The horizontal indicator (A) should be on 0 (zero). If the vehicle is level, the vertical indicator (B) should also be on 0 (zero). If the vehicle isn’t level, check the vertical aim on a level surface as soon as you can. If either indicator doesn’t read 0 (zero), adjust the headlamp aim. See “Adjusting Headlamp Aim” in the Index.
If your vehicle is damaged in an accident and the headlamp aim seems to be affected, see your Chevrolet dealer. Headlamps on damaged vehicles may require recalibration of the horizontal aim by your Chevrolet dealer. 6-40
NOTICE:
To make sure your headlamps are aimed properly, read all the instructions before beginning. Failure to follow these instructions could cause damage to headlamp parts.
State inspection stations will allow a vertical reading of plus 0.76 degrees or minus 0.76 degrees from the center of the bubble. It is recommended that the upper limit not exceed plus 0.4 degrees from the center of the bubble. Other drivers may flash their high beams at you if your adjustment is much above plus 0.4 degrees. If you find that the headlamp aiming needs adjustment, follow these steps: To adjust the aim of your headlamps: 1. Move your vehicle to a level surface. Use a spirit level
to be sure. Be sure to remove any items that are not part of your original equipment from the trunk and passenger areas. No one should be seated in the vehicle and your fuel tank should be about half full. Check to be sure your tires are at the correct pressure.

have an air-out and a serious accident. See “Loading Your Vehicle” in the Index. Underinflated tires pose the same danger as overloaded tires. The resulting accide& could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. Overinflated tires are more likely to be cut, punctured or broken by a sudden impact -- such as when you hit a pothole. Keep tires at the recommended pressure. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them. See “Inflation -- Tire Pressure” in this section for inflation pressure adjustment for higher speed driving.

Inflation -- Tire Pressure The Tire-Loading Information label, located on the driver’s door, ,shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). If you’ll be driving at speeds higher than 100 mph (160 km/h) where it is legal, raise the cold inflation pressure of each tire to 35 psi (240 Ea).

How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. Tire Inspection and Rotation Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km) for any signs of unusual wear. If unusual wear is present, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s Time for New Tires” and “Wheel Replacement” later in this section for more information.
The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See “Scheduled Maintenance Services” in the Index for scheduled rotation intervals. If you don’t have P245/5OZR16 Goodyear Eagle GS-C tires, use the rotation pattern shown above for your tires.

If you have P24515OZR16 Goodyear Eagle GS-C tires, they must roll in a certain direction for the best overall performance. The direction is shown by an arrow on the sidewall. Because these tires are directional, they should be rotated as shown here. These tires should only be moved from front to rear and rear to front side of the vehicle.

Don’t include the compact spare tire in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire-Loading Information label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.
I Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper’or wire brush later, if you need to, to get all the rust or dirt off. (See “Changing a Flat Tire” in the Index.)
When It’s Time for New Tires
One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining.
YOU need a new tire if any of the following statements are true:
You can see the indicators at three or more places around the tire.
0 You can see cord or fabric showing through the
tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric.
The tire has a bump, bulge or split. The tire has a puncture, cut or other damage that can’t be repaired well because of the size or location of the damage.
Buying New Tires To find out what land and size of tires you need, look at the Tire-Loading Information label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread design, the TPC number will be followed by an “MS” (for mud and snow). If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted ,or radial) as your original tires.

not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to Federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards.
Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. It's all right to drive with your compact spare, though. It was developed for use on your vehicle.
