How to Add Coolant to the Radiator

Notice: Your engine has a specific radiator fill
procedure. Failure to follow this procedure could cause
your engine to overheat and be severely damaged.
The radiator pressure cap is located in the front of the
engine compartment near the diagonal cross brace
on the passenger's side of the vehicle. See Engine
Compartment Overview on page 5-12
1. Turn the pressure cap slowly counterclockwise until
it first stops. (Don't press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
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.
