id0111q2800800

Warning

•  Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the engine oil have cooled.

•  A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall, causing death or serious injury. Never work around or under a lifted vehicle if it is not securely supported on safety stands.

•  Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your skin by washing with soap and water immediately after working with engine oil.

2.  Cover the area around the oil cooler with a rag because engine oil and engine coolant leak from the oil cooler installation area.

3.  Remove the oil cooler.

O-ring Installation Note

Caution

•  Do not apply engine oil, ATF, or engine coolant to the O-ring installation groove and installation surface on the oil cooler before installing the O-rings to the oil cooler.Otherwise the O-rings could swell and cause a seal malfunction. In addition, do not apply engine coolant to the O-rings for the oil passages, and do not apply engine oil to the O-ring for the coolant passage.

1.  Install new O-rings to the oil cooler.
