The air cleaner not only cleans
the air; it helps to stop flames if
the engine backfires. Use caution
when working on the engine and
do not drive with the air cleaner/
filter off.
If the vehicle has a diesel engine,
see Van Models under Cooling
System in the Duramax diesel
supplement.
The cooling system allows the
engine to maintain the correct
working temperature.
A. Radiator Pressure Cap
B. Coolant Recovery Tank
C. Engine Cooling Fan
(Out of View)
An electric engine cooling fan can
start even when the engine is not
running. To avoid injury, always
keep hands, clothing, and tools
away from any engine
cooling fan.
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is
a leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
