INSPECTION AFTER REMOVAL
Checking Reservoir Tank Cap
lInspect valve seat of reservoir tank cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.
lPull negative-pressure valve to open it, and make sure that it is
completely closed when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.
lCheck reservoir tank cap relief pressure.
–When connecting reservoir tank cap to the radiator cap tester
adapter [SST] and the radiator cap tester (Commercial service
tool), apply engine coolant to the cap seal surface.
lReplace reservoir tank cap if there is an unusualness in negative pressure valve, or if the relief pressure
falls below the limit.
CAUTION:
When installing a radiator cap and reservoir tank cap, thoroughly wipe out the radiator and reservoir
tank filler neck to remove any waxy residue or foreign material.
Checking Radiator
Check radiator for mud or clogging. If necessary, clean radiator as follows.
lBe careful not to bend or damage the radiator fins.
lWhen radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downwards.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from the radiator.
4. Blow air into the back side of radiator core vertically downwards.
lUse compressed air lower than 490 kPa (4.9 bar, 5 kg/cm2, 71 psi) and keep distance more than 30 cm
(11.8 in).
5. Blow air again into all the radiator core surface once per minute until no water sprays out.
