Removal and Installation: Inspection

Radiator

1. Check radiator for mud or clogging. If necessary, clean radiator as follows:
   • Be careful not to bend or damage the radiator fins.
   • When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator shroud and horns. Then tape the harness and electrical connectors to prevent water from entering.
   1. Apply water by hose to the back side of the radiator core, point the hose vertically downward.
   2. Apply water again to all radiator core surfaces once per minute.
   3. Stop washing when no more dirt flows off the radiator.
   4. Blow air into the back side of radiator core, point the air hose vertically downward.
      • Use compressed air lower than 490 kPa (5 kg/cm² , 71 psi) and keep distance more than 30 cm (11.8 in).
   5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
