Known Issues
|
Head Gaskets:
|
While less prevalent in the EJ22 than later EJ25s, head gasket leaks can occur. The manual will guide diagnosis and replacement.
|
Automatic Transmission:
|
Some automatic transmissions may exhibit wear over time, leading to shifting issues. The manual is critical for diagnosis.
|
Suspension Components:
|
Bushings and ball joints can wear due to age and mileage, affecting ride and handling. The manual details replacement procedures.
|
Timing Belt Tensioner:
|
The tensioner and idler pulleys should be replaced with the timing belt to prevent premature failure. The manual covers tensioner release/reset.
