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 Fan
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.
The coolant level should be at 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.
