2000 Jeep Grand cherokee limited: 4.7 v8. The oil pan..rusted

Resolved Question:

2000 Jeep Grand cherokee limited 4.7 v8.
The oil pan is blistered and rusted and I want to replace it. Is this a fairly easy task, i.e. do any of the mounts/exhaust system have to be unfastened and the engine jacked up to do this or is it easy off easy on ?

On a scale of 1 to 10 this is a 3. Without a lift, it is a 6.

The exhaust y pipe has to be removed as well as the starter.

None of the engine mounts have to be messed with and you do not have to raise the engine.


  1. Disconnect negative cable from battery.
  2. Raise vehicle on hoist.
  3. Remove structural cover.
  4. Remove exhaust system Y-pipe.
  5. Remove starter.
  6. Drain engine oil.
  7. Un-clip transmission lines from support on oil pan stud. Move lines for oil pan clearance. CAUTION: DO NOT pry on the oil pan gasket when removing the oil pan, The oil pan gasket is mounted to the cylinder block in three locations and will remain attached to block when lowering oil pan. Gasket can not be removed with oil pan.
  8. Remove oil pan bolts and oil pan.
  9. Remove oil pump pickup tube.
  10. Remove oil pan gasket.


  1. Clean oil pan and all sealing surfaces. Inspect oil pan gasket and replace as necessary.
  2. Install oil pan gasket. NOTE: When installing oil pan gasket/windage tray, start four pan bolts at each corner before tightening oil pickup tube. This will keep pan gasket in alignment.
  3. Install oil pump pick-up tube using a new O-ring. First tighten bolt at O-ring end of tube to 28 Nm (20 ft. lbs.). Tighten remain tube support fasteners to 28 Nm (20 ft. lbs.) .
