INSTALLATION
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: If the valve cover is not secured within four minutes, the sealant must be removed and the sealing area cleaned 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.
