When you decide it's safe to lift the hood, here's what
you'll see:
The coolant level should be at least up to the
ADD mark.
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.
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.
