Oil Pan: Installation

All vehicles 

NOTE: 303-01A-2 Engine - 2.5L 303-01A-2
NOTE: 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 of sealant.
1. Clean and inspect all mating surfaces.
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 prep. Allow to dry until there is no sign of wetness, or 10 minutes, whichever is longer. Failure to follow these instructions can cause future oil leakage.
