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 (5 kg/cm
