• Check valve seat (A) of radiator cap. 

- Replace the cap if the metal plunger cannot be seen around the

edge of the black rubber gasket.

- Replace the cap if deposits of waxy residue or other foreign mate-

rial are on the black rubber gasket or the metal retainer.

• Pull negative-pressure valve to open it, and check that it closes

completely when released.

- Check that there is no dirt or damage on the valve seat of radiator

cap negative-pressure valve. 

- Make sure that the valve operates properly while opening and

closing.

• Check radiator cap relief pressure using a suitable tool (A) and

Tool (B).

- When connecting the radiator cap to the Tool (B), apply water or

coolant to the cap seal surface.

- Replace radiator cap if there is an abnormality in the negative-

pressure valve, or if the radiator cap does not perform within spec-

ifications. 

CAUTION:

When installing radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue

Check radiator for mud or clogging. If necessary, clean radiator as follows.

CAUTION:

• Be careful not to bend or damage radiator fins.

• When the radiator is cleaned on-vehicle, remove the surrounding parts in order to access the radia-

tor core.

• Then tape the harness and harness connectors to prevent water from entering.
1. Spray water to the back side of the radiator core using a side-to-side motion from the top down.
2. Stop spraying when debris no longer flows from radiator core.
3. Blow air into the back side of radiator core using a side-to-side motion from the top down.

REMOVAL

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 radiator 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.
