1996 CHEVROLET CORVETTE engine overheat

Downloaded from www.Manualslib.com manuals search engine 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 SOW-90 GL-5 gear
lubricant.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed
to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
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.
A 50/50 mixture of water and the proper coolant for
your Corvette will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF ( 129 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gauges work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting GM Specification 6277M.
If
silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM
Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain
water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and
you or
others could be burned. Use
a 50/50 mix of clean
water and
DEX-COOL TM (orange-colored.
silicate-free) antifreeze.
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.

LOW
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 HOT,
or a little higher. If this
light comes on, it
means you’re
low on engine
coolant.
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.

Downloaded from www.Manualslib.com manuals search engine Adding 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.
.JTION:
r
Turning the coolant high fill reservoir pressure cap
when the engine and radiator are hot
can allow
steam and scalding liquids to blow out and burn
you badly. Never
turn the pressure cap -- even a
little
-- when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill it.

You can be burned if you spill coolant on hot

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 dealer or the procedure may be
found in a Chevrolet Corvette Service Manual.
To
purchase a service manual, see “Service and Owner
Publications” in the Index.

Downloaded from www.Manualslib.com manuals search engine Coolant High Fill Reservoir Cap
NOTICE:
Your coolant high fill reservoir 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. Be sure the
arrows on the cap line up with the overflow tube.
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.
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.

We don’t make tires. 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.
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.
CAUTION: (Continued) CAUTION: (Co

overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended

when your tires are cold.

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.
Overinflated tires are more likely to be

high-speed driving.

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your Corvette
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Corvette, see “Servicing
Your Air Bag-Equipped Corvette” in the Index.
Headlamps
The headlamp wiring is protected by a circuit breaker.
An electrical overload will cause the lamps
to go on and
off,
or in some cases to remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a fuse and
an internal circuit breaker.
If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
