WARNING:

Do not remove the radiator cap when the engine is hot. Serious burns could occur from high pressure

engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter

of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.

fitting at front-bottom surface.

CAUTION:

Lifting A/C condenser should be minimum to prevent a load

to A/C piping.

c. After removing radiator, put A/C condenser on radiator core sup-

port center to prevent a load to A/C piping, and temporarily

secure it with a suitable device.

Installation is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

• Check for engine coolant leaks. Refer to 

CO-10, "System Inspection"
