Installation

1. NOTICE: 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.
Clean the sealing surfaces with metal surface prep. Follow the directions on the packaging. Inspect the mating surfaces.
