• 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.
NOTE:
Thoroughly wipe out the radiator filler neck to remove any waxy
residue or foreign material.
• 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.
- Check that there are no abnormalities in the opening and closing
conditions of negative-pressure valve.
• Check radiator cap relief pressure using suitable tool (A) and Tool
(B).
- When connecting the radiator cap to Tool (B), apply water or
engine coolant to the cap seal surface.
- Replace the radiator cap if there is an abnormality in the negative-
pressure valve, or if the open-valve pressure is outside of the stan-
dard values.

Check radiator for mud or clogging. If necessary, clean radiator as follows.
CAUTION:
• Be careful not to bend or damage radiator fins.
• When radiator is cleaned without removal, remove all surrounding parts in order to access the radia-
tor core. Then tape 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.
3. Blow air into the back side of radiator core using side to side motion from the top down.
• Use compressed air lower than 490 kPa (5 kg/cm
2
, 71 psi) and keep distance more than 30 cm (11.81
in).
4. Continue to blow air until no water sprays out.

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-
