Installation Procedure




1. Install the oil pan gasket and the oil pump pipe screen assembly.

Notice: Refer to Fastener Notice in Service Precautions.

2. Install the oil pump pipe screen bolts.

Tighten the bolts to 15 N.m (11 lb ft).





Notice: Install the oil level sensor, located in the oil pan, after the oil pan is installed. The sensor may be damaged if the oil level sensor is installed first.

3. Identify the oil pan style.

Important: For steel oil pans, begin on step 4. For aluminum oil pans begin with step 7.




4. For steel oil pans, apply a continuous bead 6.35 mm (0.25 in) thick of RTV sealer to the top-side of the new windage tray gasket. Refer to Sealers, Adhesives, and Lubricants for the correct part number. Apply the RTV sealant directly over the sealing bead.
5. Install the new windage tray gasket onto the engine.




6. Apply a continuous bead 6.35 mm (0.25 in) thick of RTV sealer to the bottom side of the new windage tray gasket. Refer to Sealers, Adhesives, and Lubricants for the correct part number. Apply the RTV sealant directly over the sealing bead.
7. For aluminum oil pans, apply a continuous bead 6.35 mm (0.25 in) thick of RTV sealer ensuring that the sealer also completely fills the groove in the oil pan.
8. To ensure proper sealing, apply additional sealer at the four points called out in the illustration (1).




9. Install the oil pan and oil pan windage tray gasket (if applicable).
10. Clean the oil pan bolts of all debris.
11. Apply one drop of threadlock to each bolt.
12. Install the oil pan bolts.

Tighten the oil pan bolts to 14 N.m (125 lb in).
