The engine must be raised off its mounts to provide for the pan to clear the suspension crossmember. However, most of the front wheel drive models have enough clearance to provide for pan removal without raising the engine.

  1. Jack up the front of the car and support it on stands.
  3. Drain the oil.

The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize you exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

  1. Remove the underbody splash shield.
  3. On rear wheel drive cars, remove the retaining nuts from the left and right engine mounts.
  5. On rear wheel drive cars, place a jack under the bell housing. Use a board to evenly distribute the pressure and then raise the engine. Place blocks of wood between the mount and the frame to safely support the raised engine.
  7. Remove the oil pan bolts, drop the pan, and slide it out from under the car.

To install:

  1. Clean the mating surfaces of the oil pan and the engine block.
  3. Apply sealer to the engine block at the block-to-chain case and block-to-rear oil seal case joint faces, on all but the 1410 & 1468cc. On the 1410 & 1468cc engines, apply a 4mm bead of RTV sealer along the groove in the oil pan.
  5. Use a non-hardening sealer and secure a new gasket to the oil pan, on models that use a gasket.
  7. Install the oil pan. Hand-tighten the retaining bolts.
  9. Starting at one end of the pan, tighten the pan bolts to 48-72 in. lbs. in a criss-cross pattern.
  11. Lower the engine and tighten the mount retaining nuts.
  13. Install the oil pan drain plug.
  15. Install the splash shield and lower the car.
  17. Fill the crankcase with oil. Start the engine and check for leaks.
