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.
