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

CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges, which make leak paths. Use a plastic scraping tool to remove traces to sealant.

Clean all mating surfaces with metal surface cleaner.

NOTE: If the oil pan is not secured within 10 minutes of sealant application, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or 10 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.

Apply a 2.5 mm (0.09 in) bead of sealant gasket and sealant to the oil pan.
- Position the oil pan onto the engine and install the 2 rear oil pan bolts finger-tight.
