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

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.
