WARNING
Operating the engine with the air
cleaner/filter off can cause you
or others to be burned. 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.
Cooling System
If the vehicle has the Duramax
®
Diesel engine, see the Duramax
®

The cooling system allows the
engine to maintain the correct
working temperature.
