Removal Procedure

Notice: When raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal, or the crankshaft pulley. Due to the small clearance between the oil pan and the oil pump screen, jacking against the oil pan may cause the pan to be bent against the pump screen. This will result in a damaged oil pickup unit.

  2. Remove the tire and wheel. Refer to Tire and Wheel Removal and Installation .
  3. Remove the wheelhouse panel from the vehicle. Refer to Wheelhouse Panel Replacement .
