Cooling System - GMC 2003 Safari Owner's Manual

Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
The coolant level should
be at the ADD mark.
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Cooling Fan
If the coolant inside the coolant recovery tank is boiling,
don't do anything else until it cools down. The vehicle
should be parked on a level surface.
If it isn't, you may have a leak at the pressure cap or
in the radiator hoses, heater hoses, radiator, water pump
or somewhere else in the cooling system.
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them.
If you do, you can be burned.
Don't 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.
