Checking Radiator
WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
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 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.
- 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 (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 coolant leaks. Repair as necessary.
