20. NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These may cause scratches and gouges resulting in leak paths. Use a plastic scraper to clean the sealing surfaces.

Clean the sealing surfaces with silicone gasket remover and metal surface prep. Follow the directions on the packaging. Inspect the mating surfaces.


Installation

1. NOTE: The oil pump screen and pickup tube must be in the oil pan when the oil pan is positioned in the vehicle.

Position the new oil pan gasket and the oil pan in the vehicle from the rear of the engine.


2. Position the oil pump screen and pickup tube and the 3 bolts into the oil pan and position the oil pan and new oil pan gasket onto the crossmember.

3. NOTICE: Make sure the O-ring is in place and not damaged. A missing or damaged O-ring can cause foam in the lubrication system, low oil pressure and severe engine damage.

NOTE: Clean and inspect the mating surfaces and install a new O-ring. Lubricate the O-ring with clean engine oil.

Position the oil pump screen and pickup tube and install the 3 bolts.
- Tighten the 2 oil pump screen and pickup tube-to-oil pump bolts to 10 Nm (89 lb-in).

- Tighten the oil pump screen and pickup tube-to-spacer bolt to 25 Nm (18 lb-ft).


4. NOTE: If the oil pan is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Follow the directions on the packaging. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.

Apply the silicone gasket and sealant at the engine front cover-to-cylinder block mating surface.






5. NOTE: If the oil pan is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep.
