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.
4. Tighten the plug to 20 Ib-ft. (27 N-m).
Hydraulic Clutch
The clutch linkage in your vehicle is self-adjusting. The
clutch master cylinder reservoir is filled with hydraulic
clutch fluid.
It is not necessary to regularly check clutch fluid unless
you suspect there is a leak in the system. Adding fluid
won’t correct a leak.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.

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.
What to Use
To add lubricant when the level is low, use Axle
Lubricant (GM
Part No. 12345977) or SAE 8OW-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 cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL6 extended life coolant.

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.
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.
Checking Coolant
The coolant surge tank is in the engine compartment
behind the headlamp on the passenger’s side.

Downloaded from www.Manualslib.com manuals search engine Surge Tank Pressure Cap
NOTICE:
The surge tank pressure cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage
from overheating.
When you replace the surge tank pressure cap, a GM cap
is recommended.
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 pre-set temperature.
When you replace the thermostat, a
GM 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.

Downloaded from www.Manualslib.com manuals search engine How To Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then 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 level
should be at the
HOT mark.
When the engine compartment is cool, the level
should be at the
FULL COLD mark.
What to Use
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.

Brake Fluid
6
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:
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.

Downloaded from www.Manualslib.com manuals search engine Checking Brake Fluid
You can check the brake fluid without taking off the cap. NOTICE:
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.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme ll@ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
With the wrong kind of fluid in your b,,ke
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.
0 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.
0 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.

Your new Corvette comes with high-quality tires made
by a leading tire manufacturer. If you ever have
questions about your tire warranty and where to obtain
service, see your Corvette Warranty booklet for details.
Poorly maintained and improperly used tires are
dangerous.
0 Overloading your tires can cause
overheating as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle”
in the Index.

See “Inflation
Underinflated tires
pose the same danger as
overloaded tires. The resulting accident 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.

high-speed driving.

Downloaded from www.Manualslib.com manuals search engine Extended Mobility Tires
Your Corvette, when new, had Goodyear Extended
Mobility Tires (EMT). 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 Tire Pressure Monitor (TPM) is
used to alert you if a tire has lost pressure.
The Tire Pressure Monitor (TPM) has a sensor on
each road wheel that transmits to a receiver on the
instrument panel.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and with Industry and Science Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1)
this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation.
This device complies with RSS-210 of Industry and
Science Canada. Operation is subject to the following
two conditions:
(1) this device may not cause
interference, and (2) this device must accept any
interference received, including interference that may
cause undesired operation of the device. Changes
or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
If a tire’s inflation pressure is between
5 psi (35 kPa)
and 25 psi
(170 kPa), you will see a message on the
Driver Information Center. This message will show
which tire is underinflated and two chimes will sound.
An example would be LOW TIRE PRESSURE-LR.
This would mean that the inflation pressure in your left
rear tire is between
5 psi (35 Pa) and 25 psi (170 Wa).
If the inflation pressure in the tire drops below
5 psi
(35 kPa), the message would read FLAT TIRE-LR and
four chimes will sound. See “Driver Information
Center” in the Index.
The TPM will also alert you if a tire’s pressure is higher
than 42 psi (290 kPa). The message will show which tire
is overinflated and two chimes will sound. An example
would be
HIGH PRESSURE-LR. This would mean that
the inflation pressure in your left rear tire is higher than
42 psi
(290 Wa). See “Driver Information Center” in
the Index.
If a tire pressure message appears
on the Driver
Information Center, stop as soon as you can. Have the
tire pressures checked and set to those shown on your
Tire Loading Information label.
