Owner's Manual

What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
1825-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant
conforming to GM Specification 1825-M
with a complete coolant flush and refill.
If you use this mixture, you don’t need to
add anything else.
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
I’o Check Coolant When your engine is
;old, check the dipstick on the cap of the
;oolant 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.
Your Corvette also has a coolant high fill
reservoir located at the right rear of the
engine compartment.
