Oil pan — removal and installation

Note: The manufacturer recommends removing the engine and transaxle assembly to perform this procedure.

Removal

1. Drain the engine oil (see Tune-up and routine maintenance).

2. Remove the bolts and nuts that secure oil pan No. 2 (the smaller stamped steel pan) to the larger cast aluminum oil pan.

3. Oil pan No. 2 will probably be stuck to the oil pan with RTV sealant. Try tapping it loose with a rubber-tipped mallet. If you’re unable to knock it loose, carefully cut the sealant with a putty knife and a hammer. Make sure that you don’t damage the mating surfaces of the two pans.

4. Remove the two oil pump pickup tube/ strainer mounting nuts and the brace bolt. Remove the pickup/strainer assembly.

5. Remove the 16 bolts and two nuts that secure oil pan No. 1 to the engine block.

6. Carefully pry the oil pan loose from the engine block.

Caution: Only pty in the small cutout areas along the side of the pan.

7. Remove the two 0-rings from the bot- tom of the engine block. The sheet metal baffle plate can be removed at this time if necessary.

Installation

8. Install the baffle plate if you removed it. Tighten the fasteners to the torque listed in this Chapter’s Specifications.

9. Use a scraper to remove all traces of old sealant from the block and oil pan. Clean the mating surfaces with brake system cleaner.

10. Make sure the threaded holes in the block are clean. Install new 0-rings to the block, holding them in place with clean grease if required.

11. Check the flange of the steel oil pan for distortion around the bolt holes. If necessary, place it on a wood block and use a hammer to flatten and restore the gasket surface.

12. Inspect the strainer for cracks or blockage. Clean it with solvent and install it using a new gasket. Tighten the fasteners to the torque listed in this Chapter’s Specifications.

13. Apply a 1/8-inch bead of RTV sealant to the upper oil pan flange.

14. Position the pan onto the block and install the fasteners. Working from the center out, tighten the fasteners to the torque listed in this Chapter’s Specifications in several steps.

15. After you have installed the aluminum portion of the oil pan, apply a bead of RTV sealant to the flange of the No. 2 oil pan, carefully position it on the upper oil pan and install the bolts. Working from the center out, tighten them to the torque listed in this Chapter’s Specifications in several steps.

16. The remainder of installation is the reverse of removal. Add oil and install a new filter (see Tune-up and routine maintenance). Run the engine and check for leaks.
