Checking Coolant - GMC Jimmy 2004 Owner's Manual

Notice: If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost would not 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 do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.

Checking Coolant

The coolant recovery tank is located in the engine
compartment near the passenger side of the vehicle.
See Engine Compartment Overview on page 5-12
for more information on location.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at ADD,
or a little higher. When your engine is warm, the level
should be up to FULL HOT, or a little higher.
