Adding Coolant; Checking Coolant - GMC 2005 Safari 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

5-28
The engine coolant
recovery tank is located in
the engine compartment
on the passenger's 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.

Adding Coolant

If you need more coolant, add the proper DEX-COOL
coolant mixture at the coolant recovery tank, but be
careful not to spill it.
CAUTION:
{
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the
radiator. Never turn the radiator pressure
cap — even a little — when the engine and
radiator are hot.
