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.
I
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
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.
Adding Coolant
If you need more coolant, add the proper coolant
mixture at the coolant recovery tank.
