RADIATOR CAP
RADIATOR CAP : InspectionINFOID:0000000003793170
Check valve seat (A) of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
plunger (B) cannot be seen when watching it vertically from the
top.
- Check if valve seat has no soil and damage.
- Check that there is no dirt or damage on the valve seat of radiator
cap negative-pressure valve.
- Check that there are no unusualness in the opening and closing
conditions of negative-pressure valve.
Check radiator cap relief pressure.
- When connecting radiator cap to the radiator cap tester (commer-
cial service tool) and the radiator cap tester adapter (commercial
service tool) (A), apply engine coolant to the cap seal surface.
Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator pipe (upper) filler neck to remove any
waxy residue or foreign material.
RADIATOR
RADIATOR : InspectionINFOID:0000000003793171
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 such as radiator cooling fan
assembly and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.
Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm
2, 71 psi) and keep distance more than 30 cm
(11.81 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
