RADIATOR CAP : Inspection
CHECKING RADIATOR CAP
- Inspect the 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
material 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 the 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 the
radiator cap negative-pressure valve.
- Check that there are no abnormalities in the opening and closing
conditions of the negative-pressure valve.

- Check radiator cap relief pressure using suitable tool (A/B).

Standard : Refer to CO-25, "Radiator"
- Apply water or engine coolant to the cap seal surface before
connecting the radiator cap to the tester.
- Replace the radiator cap if there is an abnormality in the
negative-

- When radiator is cleaned without removal, remove all
surrounding parts such as radiator cooling fan
assembly and horns. Then tape harness and harness connectors to prevent
water from entering.
- Spray water to the back side of the radiator core using a side to
side motion from the top down.
- Stop spraying when debris no longer flows from radiator core.
- Blow air into the back side of radiator core using a side to side
motion from the top down.
- Use compressed air lower than 490 kPa (5 kg/cm2, 71 psi) and keep
distance more than 30 cm (11.8 in).
- Continue to blow air until no water sprays out.
- Check for engine coolant leaks. Repair as necessary.
