Automatic Transmission Fluid
How to Check
Because this operation is difficult, you may choose to
have this done at your Chevrolet dealer service
department. It is not necessary to check the transmission
fluid level.
A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to your
Chevrolet dealer service department and have it repaired
as soon
as possible.
There is
a special procedure for checking and changing the
transmission fluid, Contact your Chevrolet dealer for
Corvette Service Manual.
To purchase a service manual,
see “Service and Owner Publications” in the Index.
- additional information or the procedure can be found in a
NOTICE:
We recommend that only fluid labeled
DEXR0N’-I11 be used, because fluid with that
label
is made specially for your automatic
transmission. Damage caused by fluid other than DEXRON@-I11 is not covered by your new
vehicle warranty.

Downloaded from www.Manualslib.com manuals search engine Change both the fluid and filter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90” F (32” C) or higher.
In hilly or mountainous terrain.
0 High performance operation.
If you do not use your vehicle under one of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services” in the Index for
the proper service intervals for the transmission fluid
and filter.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual
transmission doesn’t require changing.
How to Check
Because this operation can be difficult, you may
choose to have this done at your Chevrolet dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading.
I NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some
of the fluid could come out and fall on hot
exhaust system parts, starting a fire. Be sure to
1 get an accurate reading if you check your
transmission fluid.
Check the fluid level only when your engine is off, the
vehicle is parked on a level place and the transmission is
cool enough for you to rest your fingers
on the
transmission case.

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.

add coolant when it is low.
If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.

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.

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
