Checking Coolant - Chevrolet 2001 Prizm Owner's Manual

NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn't be covered by your
warranty. Too much water in the mixture 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

Adding Coolant
If you need more coolant, add the proper coolant
mixture at the coolant recovery tank, but be careful
not to spill it.
The vehicle must be on a
level surface. When your
engine is cold, the coolant
level should be at LOW, or
a little higher. When your
engine is warm, the level
should be up to FULL, or
a little higher.
