1995 Chevrolet Corvette Owners Manual

for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or 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 used oil, ask your dealer, a service station or a local recycling center for help.

Air Cleaner

Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Index.

Air Filter Replacement

I 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.

To remove the air filter: 1. Unscrew the three knobs.

6-18

2. Disconnect the clamp from the manifold.

3. Pull the air cleaner straight up. 4. Open the air cleaner and remove the filter.

Automatic Transmission Fluid When to Check and Change A good time to check your automatic transmission fluid level is when the engine oil is changed. Refer to the Maintenance Schedule to determine when to change your fluid. See “Scheduled Maintenance Services” in the Index. How to Check Because this operation can be a little difficult, you may choose to have this done at your Chevrolet dealer 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.

I I 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.

5. Reverse the steps.

0 Align the tabs to the slots in the bottom of the

assembly before you replace it.

0 Install the short knob into the middle hole first.

Then install the longer knobs into the outer holes.

6-20

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). At high speed for quite a while. In heavy traffic -- especially in hot weather.

To get the right reading, the fluid should be at normal operating temperature, which is 1 80°F to 200°F (82 "C to 93 " C). To check transmission fluid hot: Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). You may have to drive longer to bring the fluid to 180°F to 200" F (82°C to 93 "C) in colder outside temperatures. See "Automatic Transmission Fluid Temperature Reading" in the Index. To check 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.

To check 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:

1. Pull out the dipstick and wipe it with a clean rag or

paper towel.

6-21

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. Don ’t ove@ZZ. 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.”

a When the correct fluid level is obtained, push the

dipstick back in all the way.

2. Push it back in all the way, wait three seconds and

then pull it back out again.

3.

4.

Check both sides of the dipstick, and read the lower level. The fluid level should be in the area marked “80°F” for a cold check and will move into the “WARM” area as the temperature increases. When the fluid is at normal operating temperature ( 180 O F to 200”F, 82°C to 93”C), the level must be in the crosshatched area marked “1 90°F.” See “Automatic Transmission Fluid Temperature Reading” in the Index. If the fluid level is in the acceptable range, push the dipstick back in all the way.

6-22

Manual Transmission Fluid How to Check Because this operation can be difficult, you may choose to have this done at your Chevrolet dealer 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 if you check your sure to get an accurate reading 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.

6-23

When to Check and What to Use

Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid. See “Owner Checks and Services” and “Recommended Fluids and Lubricants” in the Index.

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 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.

6-24

How To Check and Add Fluid (LT1 Engine Only) The clutch master cylinder is under the Powertrain Control Module (PCM) in the left rear area of the engine ADD mark on the reservoir. There are additional compartment. To check the fluid, look at the area between the PCM and the battery. To add fluid, remove the PCM unit.

You must loosen and remove the two screws before the PCM unit will lift out. Fluid should be added if the fluid level is at or below the

instructions on the reservoir cap. When returning the PCM to its proper position, make sure the unit is fully rearward in the bracket prior to installing the two screws. How to Check and Add Fluid (LT5 Engine Only) The clutch master cylinder is under the Engine Control Module (ECM) in the left rear area of the engine compartment. To check the fluid, look at the area and the battery. To add fluid, remove the ECM unit

between the ECM

6-25

Rear Axle When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Periodic Maintenance Inspections” in the Index. How to Check Lubricant

Loosen the two inboard nuts on the unit. Move the ECM unit to either side. Fluid should be added if the fluid level is at or below the ADD mark on the reservoir. There are additional instructions on the reservoir cap. When returning the ECM to its proper position, make sure the bolts are aligned with the slots in the bracket. Then gently push down on the unit. When replacing the unit, be careful not to over-tighten the nuts --just tighten them until they are snug.

6-26

If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to

the bottom of the filler plug hole.

What to Use Use a mixture of one-half clean water (preferably distilled) and one-half antifreeze that meets “GM Specification 1825M,” which won’t damage aluminum parts. You can also use a recycled coolant conforming to GM Specification 1825M with a complete coolant flush and refill. Use GM Engine Coolant Supplement (sealer) with any complete coolant flush and refill. If you use this mixture, you don’t need to add anything else.

What to Use To add lubricant when the level is low, use Axle Lubricant (GM Part No. 12345977) or SAE SOW-90 GL-5 gear lubricant. To completely refill after draining, add 4 ounces (1 18 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) or SAE 8OW-90 GL-5 gear lubricant. Engine Coolant 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 high fill reservoir, see “Engine Overheating” in the Index. The proper coolant for your Corvette will:

Give freezing protection down to -34°F (-37°C). Give boiling protection up to 262 “F (128 ” C). Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights work as they should.

6-27

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.

Adding Coolant To Check Coolant 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 the HOT, or a little higher.

6-28

Your Corvette also has a high fill reservoir located at the right rear of the engine compartment. If the recovery tank is very low or empty, also add coolant to the high fill reservoir. To add coolant at the high fill reservoir, see “Engine Overheating” in the Index.

To Add Coolant to the Recovery Tank 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 coolant high fill reservoir, see “Engine Overheating” in the Index for information.

Add coolant mix at the recovery tank, but be careful not to spill it.

6-29

1 Power Steering Fluid

A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

0 When the engine compartment is hot the level should

be at the HOT or H mark.

0 When the engine compartment is cool, the level

should be at the COLD or C mark.

LT5 Engine

LTl Engine 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. The level should be at the FULL COLD mark. Add enough fluid to bring the level up to the mark.

6-30

What to Add Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index.

To Add

NOTICE: When adding power steering fluid or making a complete fluid change, 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.

Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is full.

6-31

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.

0 Fill your washer fluid tank only 3/4 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.

6-32

Brakes Brake Master Cylinder Your brake master cylinder is here. It is filled with DOT-3 brake fluid.

There are only two reasons why the brake fluid level in your master cylinder 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.

On vehicles equipped with the LT5 (Code J) engine, the brake warning light will come on when your brake fluid falls to a low level. See “Brake System Warning Light” in the Index. For vehicles equipped with the LT1 (Code P) engine, refer to the Maintenance Schedule to determine when to check your brake fluid. See “Periodic Maintenance Inspections” in the Index. To Check 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 MIN mark on 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 between the MIN and MAX marks.

6-33

Brake Wear Your Corvette has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make 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 on the brake pedal firmly).

What to Add When you do need brake fluid, use only DOT-3 brake fluid -- such as Delco Supreme ll@ (GM Part No. 1052535). Use new brake fluid from a sealed container only, and always clean the brake fluid reservoir cap before removing it.

NOTICE: 0 Don’t let someone put in the wrong kind of

fluid. 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. Brake fluid can damage paint, so be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

6-34

NOTICE:

I Continuing to drive with worn-out brake pads

could result in costly brake repair.

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. 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 As you make brake stops, your disc brakes automatically adjust for wear.

Replacing Brake System Parts The braking system on a modem 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 Corvette 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 if someone puts in the wrong replacement brake parts. Battery Every new Corvette 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. For battery replacement, see your dealer or the Corvette Service Manual. To purchase a service manual, see “Service Publications” in the Index.

6-35

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.

Tires We don’t make tires. Your new vehicle comes with high-quality tires made by a leading tire manufacturer. These tires are warranted by the tire manufacturers and their warranties are delivered with every new Corvette. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.

6-48

Extended Mobility Tires (Option) If your Corvette has optional Goodyear Extended Mobility Tires (EMT’s), the tires will have “EMT” molded on the sidewalls. Your vehicle may also have a spare tire delete option. With the spare tire delete option, there’s no spare tire, no tire changing equipment and no place to store a tire in the vehicle. Extended Mobility Tires perform so well without any air that a Low Tire Pressure Warning System (LTPWS) is used to alert you if a tire has lost pressure. A LOWELAT TIRE light will appear on your Driver Information Center if a tire’s inflation pressure is less than 25 psi (170 kPa). If the LOW/FLAT TIRE light comes on, check your tire pressures as soon as you can. See “Low Tire Pressure Warning System” in the Index for additional information.

If a tire goes flat, you won’t need to stop on the side of the road to change the tire. You can just keep on driving. The shorter the distance you drive and the slower the speed, the greater the chance that the tire will not have to be replaced. If you drive on a deflated EMT for distances of 50 miles (80 km) or less and at speeds of 55 mph (90 km/h) or less, there is a good chance that the tire can be repaired. The tire can operate effectively with no air pressure for up to 200 miles (320 km) at speeds up to 55 mph (90 kmk), but the tire would then have to be replaced. Also remember: When a tire is filled with air, it provides a cushion between the road and the wheel. Because you do not have this cushion when driving on a deflated tire, try to avoid potholes that could damage your wheel and require replacement of it. Some road hazards can damage a tire beyond repair. This damage could occur before you’ve driven on the tire in a deflated condition. Whenever a tire has been damaged, or if you’ve driven any distance on a deflated EMT, check with a Goodyear EMT Service Center to determine whether the tire can be repaired or should be replaced. To maintain your vehicle’s extended mobility feature, all replacement tires must be Extended Mobility Tires. See the Goodyear Extended Mobility Tire Owner’s Manual and Limited Warranty supplied with your Corvette for additional information.

6-49

I

I NOTICE: (Continued)

If your tires have too much air (overinflation), you can get: 0 Unusual wear 0 Bad handling 0 Rough ride 0 Needless damage from road hazards.

When to Check Check your tires once a month or more. Don’t forget your compact spare tire. It should be at 60 psi (420 Wa). How to Check Use a good quality pocket-type gage to check tire pressure. Simply looking at the tires will not tell you the pressure, especially if you have radial tires -- which may look properly inflated even if they’re underinflated. If your tires have valve caps, be sure to put them back on. They help prevent leaks by keeping out dirt and moisture.

Inflation - Tire Pressure

The Tire-Loading Information label which is 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 a mile. For competitive driving or high-speed driving (over 150 mph or 240 km/h), make sure your tires are inflated to 35 psi (240 Wa). When you end this type of driving, reduce the “cold” inflation pressures (if necessary) to those listed on the Tire-Loading Information label.

I I NOTICE:

Don’t let anyone tell you that underinflation or overidation is all right. It’s not. If your tires don’t have enough air (underinflation) you can get:

Too much flexing

0 Too much heat

Tire overloading Bad wear

0 Bad handling 0 Bad fuel economy.

6-50

(Continued)

Tire Rotation The tires on your Corvette are directional, asymmetrical, and are different sizes front to rear. Due to this, your tires should not be rotated. Each tire and wheel should be used only in the position it is in.

When it’s Time for New Tires

You need a new tire if

You can see the indicators at three or more places around the tire. You can see cord or fabric showing through the tire’s rubber.

0 The tread or sidewall is cracked, cut or snagged deep

enough to show cord or fabric. The tire has a bump, bulge or split.

0 The tire has a puncture, cut, or other damage that

can’t be repaired well because of the size or location of the damage.

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.

6-51

Buying New Tires To find out what kind 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.

6-52

Uniform Tire Quality Grading The following information relates to the system developed by the United States National Highway Traffic Safety Administration which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.)

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.

Traction - A, B, C

The traction grades, from highest to lowest are: A, B, and C. They represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not include cornering (turning) traction. Temperature - A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and

excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Warning: The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. These grades are molded on the sidewalls of passenger car tires. While the tires available as standard or optional equipment on General Motors vehicles may vary with respect to these grades, all such tires meet General Motors performance standards and have been approved for use on General Motors vehicles. All passenger type (P Metric) tires must conform to Federal safety requirements in addition to these grades.

6-53

Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. In most cases, you will not need to have your wheels aligned again. However, if you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced. Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your Chevrolet dealer if any of these conditions exist. Your dealer will know the lund of wheel you need. Each new wheel should have the same load carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them only with new GM original

6-54

equipment parts. This way, you will be sure to have the right wheel, wheel bolts, and wheel nuts for your Corvette model.

I NOTICE:

The wrong wheel can also cause problems with bearing life, brake cooling, speedometer/odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire clearance to the body and chassis.

Used Replacement Wheels

Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your Corvette, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside. Never use these to clean your vehicle:

Tire Chains

NOTICE: Don’t use tire chains; they can damage your vehicle.

Gasoline Benzene Naphtha Carbon Tetrachloride Acetone Paint Thinner Turpentine Lacquer Thinner Nail Polish Remover

They can all be hazardous -- some more than others -- and they can all damage your vehicle, too.

Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: 0 Alcohol 0 Laundry Soap

Bleach Reducing Agents

Cleaning the Inside of Your Corvette Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your Chevrolet dealer has two GM cleaners, a solvent-type spot lifter and a foam-type powdered cleaner. They will clean normal spots and stains very well. Do not use them on vinyl or leather. Here are some cleaning tips: 0 Always read the instructions on the cleaner label.

Clean up stains as soon as you can -- before they set. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. 0 Use solvent-type cleaners in a well-ventilated area

only. If you use them, don’t saturate the stained area. If a ring forms after spot cleaning, clean the entire area immediately or it will set.

6-56

Using Foam-Type Cleaner on Fabric

Vacuum and brush the area to remove any loose dirt. Always clean a whole trim panel or section. Mask surrounding trim along stitch or welt lines. Mix Multi-Purpose Powdered Cleaner following the directions on the container label. Use suds only and apply with a clean sponge. Don’t saturate the material. Don’t rub it roughly. As soon as you’ve cleaned the section, use a sponge to remove the suds. Rinse the section with a clean, wet sponge. Wipe off what’s left with a slightly damp paper towel or cloth. Then dry it immediately with a blow dryer or a heat lamp.

NOTICE: Be careful. A blow dryer or a heat lamp may scorch the fabric.

0 Wipe with a clean cloth.

Using Solvent-Type Cleaner on Fabric First, see if you have to use solvent-type cleaner at all. Some spots and stains will clean off better with just water and mild soap. If you need to use a solvent: 0 Gently scrape excess soil from the trim material with a clean, dull knife or scraper. Use very little cleaner, light pressure and clean cloths (preferably cheesecloth). Cleaning should start at the outside of the stain, “feathering” toward the center. Keep changing to a clean section of the cloth. When you clean a stain from fabric, immediately dry the area with a blow dryer to help prevent a cleaning ring. (See the previous NOTICE.)

Fabric Protection Your Corvette has upholstery and carpet that has been treated with Scotchgard” Fabric Protector, a 3M product. Scotchgard TM protects fabrics by repelling oil and water, which are the carriers of most stains. Even with this protection, you still need to clean your upholstery and carpet often to keep it looking new. Further information on cleaning is available by calling 1-800-433-3296 (in Minnesota, 1-800-642-6167).

Special Cleaning Problems Greasy or Oily Stains Stains caused by grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt can be removed as follows:

Carefully scrape off excess stain. Follow the solvent-type instructions described earlier. Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle seat fabric. They should be removed as soon as possible. Be careful, because the cleaner will dissolve them and may cause them to spread.

Non-Greasy Stains Stains caused by catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine, vomit, urine and blood can be removed as follows:

Carefully scrape off excess stain, then sponge the soiled area with cool water. If a stain remains, follow the foam-type instructions described earlier.

6-57

If an odor lingers after cleaning vomit or urine, treat the area with a waterhaking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. If needed, clean lightly with solvent-type cleaner.

Combination Stains Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown stains can be removed as follows: Carefully scrape off excess stain, then clean with cool water and allow to dry. If a stain remains, clean it with solvent-type cleaner.

Cleaning Vinyl Use warm water and a clean cloth.

Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and a GM VinylLeather Cleaner or equivalent product.

Cleaning Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap. 0 For stubborn stains, use a GM Vinylkeather Cleaner

or equivalent product.

0 Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather. 0 Soiled leather should be cleaned immediately. If dirt

is allowed to work into finish, it can harm the leather.

Cleaning Soft-Touch Surfaces Use only mild soap and water to clean the Soft-Touch paint surfaces in your Corvette. Cleaning Dulso-Coated Moldings These moldings are around the hatch opening in your Corvette’s rear area. 0 When lightly soiled, wipe with a sponge or soft

lint-free cloth dampened with water.

0 When heavily soiled, use warm soapy water.

6-58

You can remove scratches from a Dulso-coated molding by wiping briskly with the solvent-type cleaner described earlier. If a ring forms, repeat the procedure over a larger area, feathering toward the center of the ring. If the ring still remains, wipe the whole molding. Cleaning the Top of the Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions. Cleaning Speaker Covers Vacuum around a speaker cover gently, so that the speaker won’t be damaged. If something gets on one of them, follow the steps earlier under “Using Solvent-Type Cleaner on Fabric.” Use as little solvent as you can.

Care of Safety Belts Keep belts clean and dry.

Glass Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smoke and dust films. Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid.

6-59

Cleaning the Outside of the Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax or other material may be on the blade or windshield. Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami Powder@ (GM Part No. 1050011). The windshield is clean if beads do not form when you rinse it with water. If you use a glass treatment or conditioner containing ethyl alcohol or ethyl sulfate on your glass, be sure to remove the acrylic roof panel, if so equipped. These products may darnage the panel. Clean the blade by wiping vigorously with a cloth soaked in full strength windshield washer solvent. Then rinse the blade with water. Wiper blades should be checked on a regular basis and replaced when worn.

Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. (See “Recommended Fluids and Lubricants” in the Index.) Cleaning a Removable Roof Panel Special care is necessary when cleaning, removing and/or storing the roof panel.

Flush with water to remove dust and dirt, then dry the panel. Clean the panel with GM Glass Cleaner. Leave the cleaner on the panel for one minute, then wipe the panel with a soft, lint-free cloth. Don’t use abrasive cleaning materials.

If water drops are frequently allowed to dry on the roof panel, impurities in the water will adhere to the top. These impurities may destroy the finish. When the panel gets wet, you should dry it o€f.

6-60

NOTICE: Do not use a glass treatment or conditioner containing ethyl alcohol or ethyl sulfate on the roof panel. These products may damage the panel.

Cleaning the Outside of Your Corvette The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Don’t wash your vehicle in the direct rays of the sun. Don’t use strong soaps or chemical detergents. Use liquid hand, dish or car washing (mild detergent) soaps. Don’t use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on

the surface, or they could stain. Dry the finish with a soft, clean chamois or a 100% cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter your vehicle.

I NOTICE:

Conveyor systems on some automatic car washes may damage a Corvette. They may not have enough clearance for the undercarriage or for the extra wide rear tires on ZR-1 models. Check with the manager before using a car wash.

Finish Care Occasional waxing or mild polishing of your Corvette by hand may be necessary to remove residue from the paint finish. You can get GM approved cleaning products from your dealer. (See “Appearance Care and Materials” in the Index.)

6-6 1

Your Corvette has a “basecoatklearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoatklearcoat paint finish.

Machine compounding or aggressive polishing on a basecoatlclearcoat paint finish may dull the finish or leave swirl marks.

Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc. can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint finish looking new by keeping your Corvette garaged or covered whenever possible.

Cleaning Your Convertible Top Your convertible top should be cleaned often. If you use an automatic car wash, use one with water jets and hanging cloths. When you hand wash the top, do it in partial shade. Vacuum away any dust and other material. Use a mild soap, lukewarm water and a soft sponge. A chamois or cloth may leave lint on the top, and a brush can chafe the threads in the top fabric. Don’t use detergents, harsh cleaners, solvents or bleaching agents. When you clean the top, put one hand under it to support it. Wet the entire vehicle and wash the top evenly to avoid spots or rings. Let the soap remain on the fabric for a few minutes. When the top is really dirty, use a mild foam-type cleaner. Thoroughly rinse the entire vehicle, then let the top dry in direct sunlight. To protect the convertible top: 0 After you wash the vehicle, make sure the top is

completely dry before you lower it.

0 Don’t get any cleaner on the vehicle’s painted finish;

it could leave streaks.

0 If you decide to go through an automatic car wash,

ask the manager if the equipment could damage your top.

6-62

Cleaning and Storage of Your Hardtop The optional hardtop has the same durable finish as the painted surfaces of your Corvette. You can wash, polish and wax it. If you store the hardtop for a long time, keep it covered in a dry place. Apply silicone grease to all the weatherstrips. Engine Cleaning Use care when cleaning the LT5 engine. Do not direct water into the “V” area on the engine between the cylinder heads.

NOTICE: Don’t use a cleaner with a strong alkaline base. It will discolor the aluminum.

Aluminum Wheels Your aluminum wheels have a protective coating similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, chrome polish, abrasive cleaners or abrasive cleaning brushes on them because you could damage this coating. After rinsing thoroughly, a wax may be applied.

I NOTICE:

Don’t use an automatic vehicle wash that has hard silicon carbide cleaning brushes. These brushes can take the protective coating off your aluminum wheels.

Tires To clean your tires, use a stiff brush with a tire cleaner. When applying a tire dressing always take care to wipe off any overspray or splash from painted surfaces. Petroleum-based products may damage the paint finish.

6-63

the finish

Finish Damage Any stone chips, fractures or deep scratches in- should be repaired right away. Minor chips and scratches can be repaired with touch-up materials available from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your dealer or an underbody vehicle washing system can do this for you.

Fiberglass Springs

NOTICE: Don’t use corrosive or acidic cleaning agents, engine degreasers, aluminum cleaning agents or other harsh solvents to clean fiberglass springs; they’ll damage the springs.

Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, Chevrolet will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 1 2 months or 12,000 miles (20 000 km) of purchase, whichever comes first.

Vehicle Identification Number (VIN)

1.

Service Parts Identification Label You’ll find this label on the inside of your rear storage compartment. It’s very helpful if you ever need to order parts. On this label is:

ENGINE / li!95\

SAMPLEjUXSM072675

YEAR

PLANT

MODEL

CODE

ASSEMBLY

your VIN, the model designation, 0 paint information, and

a list of all production options and special equipment.

Be sure that this label is not removed from the vehicle.

This is the legal identifier for your Corvette. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certification and Service Parts labels and the certificates of title and registration. Engine Identification The eighth character in your VIN is the engine code. This code will help you identify your engine, specifications, and replacement parts.

6-66

Add-on Electrical Equipment

Fuses & Circuit Breakers

NOTICE: Don’t add anything electrical to your Corvette unless you check with your dealer first. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should.

Your vehicle has an air bag system. Before attempting to add anything electrical to your Corvette, see “Servicing Your Air Bag-Equipped Corvette” in the Index.

The wiring circuits in your vehicle are protected from short circuits by a combination of maxi-fuses, mini-fuses, and circuit breakers. This greatly reduces the chance of fires caused by electrical problems.

6-67

There are three fuse centers on your vehicle. One is in the right side of your instrument panel. Turn the knob and pull the door to access the fuses.

The other two fuse blocks are in the engine compartment. One is part of the Forward Lamp wiring harness (A), and the other is part of the ECM-Engine wiring harness (B). Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the correct size.

6-68

If you ever have a problem on the road and don’t have a spare fuse, you can borrow one of the correct value. Just pick some feature of your vehicle that you can get along without -- like the radio or cigarette lighter -- and use its fuse, if it is the size you need. Replace it as soon as you can. Headlamp Wiring The headlamp wiring is protected by a circuit breaker in the switch. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away. Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem and not snow, etc., be sure to get it fixed. Power Windows and Other Power Options Circuit breakers protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed or goes away.
