ACTIVE
When your ASR system is
limiting wheel spin, the
ASR ACTIVE light will
come on. Slippery road
conditions may exist
if this
light comes on,
so adjust
your driving accordingly.
The light will stay on for a few seconds after the ASR
system stops limiting wheel spin.
The ASR ACTIVE light also comes on briefly, as a bulb
check, when the engine is started. If the light doesn’t
come on then, have it fixed
so it will be there to tell you
when the system is active.

This gauge shows the engine coolant temperature. If the
gauge pointer moves into the shaded area, your engine is
too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull
off the road, stop your
vehicle and turn
off the engine as soon as possible.
Hot Coolant Can Bum You Badly!
In “Problems on the Road,” this manual shows what to

isn’t, you may have a leak in the radiator hoses, heater
hoses, radiator, water pump or somewhere else in the
cooling system.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on check to
see if the electric engine fan(s) are running.
If the engine
is overheating, both fan(s) should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the ,coo,lant level
isn’t at or above the COLD mark, add
a 50MI mixture
of clean water (preferably distilled) and a proper
antifreeze at the coolant recovery tank. (%e “Engine
Coolant” in the Index for more information about the
proper coolant mix.)

Downloaded from www.Manualslib.com manuals search engine What to Use 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 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.
