Refer to the Maintenance Schedule to determine when to
replace the air filter.
See "Scheduled Maintenance Services" in the Index.
A CAUTION:
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.

When to Check and Change
A good time to check your automatic transmission fluid
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:
In heavy city traffic where the outside temperature
In hilly or mountainous terrain.
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.
How to Check
Because this operation can be a little difficult, you
may choose to have this done at your Corvette
dealership Service Department.
regularly
reaches 90
OF (32 O C) or higher.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
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.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 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
180°F to 200°F
(82°C to 93°C).

Downloaded from www.Manualslib.com manuals search engine 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.
0 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.
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 Corvette 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.

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 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.

Downloaded from www.Manualslib.com manuals search engine When to Check and What to Use How To Check and Add Fluid
The clutch master cylinder is under the Powertrain
Control Module (PCM) in the left rear area of the engine
compartment.
To check the fluid, look at the area between the PCM
and the battery.
To add fluid, remove the PCM unit.

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.
You must loosen and remove the two screws before the
PCM unit will lift out.

ADD mark on the reservoir. There are additional
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.

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
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.

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. If necessary,
add
only enough fluid to bring the level up to the mark.
When the engine
compartment is hot
the kvel should be
at the

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.

Downloaded from www.Manualslib.com manuals search engine 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.
--
A CAUTION: 3
-
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.
