CAUTION
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 your 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 dipstick.
  2.  
  3. On models with automatic transmission, remove the torque converter inspection cover.
  4.  
  5. Raise and support the front end on jackstands placed under the frame. This will drop the driving axle far enough to clear the pan.

  12.  
  13. When installing the pan, coat the block and pan mating surfaces with sealer and place a new gasket on the pan. Place new rubber end seals in the pan. Put a 1 / 8 " drop of silicone sealer at the 4 points where the seals and gaskets meet.
  14.  

On models using RTV silicone material instead of a gasket, apply a 1 / 8 " diameter bead of seal on the pan, around the bolt holes.

On models with a gasket, position the pan and install the bolts. Tighten the bolts to 75 in. lbs., then, retighten the bolts to 200 in. lbs.

On models with RTV silicone sealant in place of a gasket, torque the bolts to 200 in. lbs.
