Cooling System | Chevrolet 2001 guide

Cooling System

When you decide it's safe to lift the hood, here's what you'll see:

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.

When the engine is cold, the coolant level should be at least up to the ADD mark. If it isn't, you may have

a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.
