Oil Pan


Removal & Installation

  1. Before servicing the vehicle, refer to the Precautions Section.
  3. Drain the crankcase.
  5. Remove or disconnect the following:

    Negative battery cable
    Oil level indicator harness connector, if equipped
    Exhaust crossover pipe
    Transaxle assembly from the vehicle, if necessary
    Oil pan bolts and the oil pan


To install:

The oil pan gasket is reusable unless it is damaged. Do not remove the gasket from the oil pan groove unless gasket replacement is required.

  1. Thoroughly clean the inside of the oil pan and the cylinder block contact surface. If the oil pan gasket is being reused, be careful not to damage it. Do not expose the gasket to cleaning solvents.
  3. If a new gasket is being installed, start the gasket into the oil pan groove and work the gasket into the groove in both directions. Once the gasket is exposed to oil, it will expand and no longer stay in the groove without wrinkles. If this condition exists, replace the gasket.
  5. Install or connect the following:

    Oil pan. Torque the bolts in sequence to 89 inch lbs. (10 Nm).
