Installation Procedure






Important: The oil pan must be installed within 10 minutes from when sealer was applied.

1. Apply a 3 mm (0.12 in) bead of sealer to the block, rather than the oil pan.

Important: When you install the oil pan, it could be shifted front or back a little which could cause a transmission alignment problem. The back of the oil pan needs to be flush with the block.

2. Install the oil pan, maneuvering the oil pan to clear the oil pump and screen assembly.

3. Install the oil pan bolts.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.






4. Inspect the oil pan alignment. Use a straight edge on the back of the block and the oil pan transmission mounting surface.
