Check radiator for mud or clogging. If necessary, clean radiator as follows.
CAUTION:
- Be careful not to bend or damage the radiator fins.
- When radiator is cleaned on-vehicle, remove surrounding parts in order to access the radiator core. Tape the harness and electrical 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 (4.9 bar, 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.
