Radiator Pressure Cap; If Steam Is Coming From Your Engine; Engine Overheating - GMC 2004 Canyon Owner's Manual

Add coolant mixture at the recovery tank, but be careful
not to spill it.
CAUTION:
{
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
see Cooling System on page 5-30.

Your air conditioning may stop working if your engine is
too hot. This is normal and helps cool the engine.
