4. Disconnect the oxygen sensor connector. Remove and discard the exhaust pipe-to-manifold nuts. Move the exhaust pipe aside and support it with a jack.
5. Remove the oil pan bolts and the oil pan.

   To install:

6. Clean the oil pan. Clean all dirt, oil, gasket and old sealant from the oil pan and cylinder block contact surfaces.
7. Apply a continuous bead of silicone sealant on the gaskets and around the oil pan, going on the inside of the bolt holes.
8. Position the gaskets on the oil pan. Install the oil pan, and tighten the vertical bolts to 70–95 inch lbs. (8–11 Nm), and the horizontal bolts to 28–38 ft. lbs. (38–51 Nm).
9. Connect the exhaust pipe to the manifold with new nuts. Tighten the nuts to 28–38 ft. lbs. (38–51 Nm). Connect the oxygen sensor connector.
10. Install the transverse member, and tighten the mounting bolts to 69–97 ft. lbs. (94–131 Nm).
11. Install the right-hand splash shield and tighten the mounting bolts to 70–95 inch lbs. (8–11 Nm). Lower the vehicle.
12. Fill the engine with the proper type and quantity of engine oil. Connect the negative battery, run the engine and check for leaks.
