WARNING: This page is about a different car, the 2003 Nissan Altima. 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.
- 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 connectors to prevent water from entering.
- Apply water by hose to the back side of the radiator core vertically downward.
- Apply water again to all radiator core surfaces once per minute.
- Stop washing when clear water flows off of the radiator.
- Blow air into the back side of radiator core vertically downward.
- Use compressed air lower than 490 kPa (5 kg/cm2 , 71 psi) and keep distance more than 300 mm (11.8 in).
- Blow air again into all the radiator core surfaces once per minute until no water sprays out.
- Check for leakage.
