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.
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.
6-26

Downloaded from www.Manualslib.com manuals search engine What to Use 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. 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.

Downloaded from www.Manualslib.com manuals search engine 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. 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.
6-28

Downloaded from www.Manualslib.com manuals search engine 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.

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.

Downloaded from www.Manualslib.com manuals search engine What to Add
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids
and
Lubricants” in 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.
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.
To Add
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is full.

Downloaded from www.Manualslib.com manuals search engine 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.

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’
6-32

Downloaded from www.Manualslib.com manuals search engine 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

Downloaded from www.Manualslib.com manuals search engine 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.
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).

Replacing Brake System Parts
The braking system on a modem vehicle is complex. Its
I
Continuing to drive with worn-out brake pads
could result in costly brake repair.
I
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. 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.
