If you need to add 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.
. . .190
Add coolant mix at the recovery tank, but
be careful not to spill it.
NOTICE:
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.
For complete drain, flush and refill
of
the engine, contact your Chevrolet
jealer or the procedure may be found in
3 Chevrolet Corvette Service Manual. To
purchase a service manual, see “Service
Publications” in the Index.
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
How to Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and
completely tighten it.
5.7L LT5 (Code J)
Then remove the cap again and look at
the fluid level on the dipstick.
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.
What to Add:
Refer to the Maintenance Schedule to
determine what kind
of fluid to use. See
“Recommended Fluids and Lubricants” il
the Index.

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.
L
Windshield Washer Fluid
To Add:
Open the cap labeled “WASHER FLUID
ONLY.” Add washer fluid until the bottle
is full.
NOTICE:
0 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.
0 Don’t use radiator antifreeze in
your windshield washer. It can
damage your washer system and
paint.

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. When your brake fluid falls to a
low level, your brake warning light,
“SERVICE ABS” light and “SERVICE
ASR” light will come on. Also, the
anti-lock brake and Acceleration Slip
Regulation systems are disabled. See
“Brake System Warning Light” in the
Index.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid
- such as Delco-
Supreme
1 l@ (GM Part No. 1052535).
Use new brake fluid from a sealed
container only, and always clean the brak
fluid reservoir cap before removing it.

NOTICE:
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.
Brake Wear
Your Corvette has four-wheel disc 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
on the brake pedal
firmly).
I 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 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 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.

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 catalog 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.
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. Contact your
dealer to learn how to
prepare your vehicle for longer storage
periods.
