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-COOL’ extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see “Engine Overheating” in
the Index.
A
50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
8
0 Give boiling protection up to 265 “F (129” C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gauges work as
they should.

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.

hook. Pull up until the pivot locking tab locks
in the hook slot.
4. Carefully lower the wiper arm and blade assembly
into the windshield.
Tires
Your new vehicle 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.
A CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause overheating
as a result of too much friction. You could
have an airout and a serious accident.
See
‘Zoading Your Vehicle” in the Index.
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.
