INSTALLATION
1. Clean and inspect the mating surface.
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 all traces of old sealant.
NOTE: Clean sealing surfaces with Metal Surface Cleaner F4AZ-19A536-RA or equivalent meeting Ford specification WSE-MSB392-A. Allow
to dry until there is no sign of wetness, or four minutes, whichever is longer, failure to follow this procedure can cause future oil leakage.
