Known Problems

The idler arm, pitman arm, or center steering link may wear and cause excess play in the steering. If any of these components are replaced, the front end alignment should be checked.

The spark plug wire rubber boots may get soaked with oil, causing a misfire or rough idle.

On vans with rear AC, the AC may stop blowing cold air due to a damaged AC line near the back of the engine. It is common for these lines to rub on the engine block, causing a hole in the line and a refrigerant leak.

The alternator may fail, causing a "no charge" condition. An internal bearing may also fail and cause an abnormal noise. If the vehicle is driven too long with a failed bearing, the alternator may stop turning, which can cause the serpentine belt to break or the engine to stall and not turn over.

Timing gears may wear causing a mild to severe knocking noise from the front of the engine. Replacement of the timing gears is necessary.
