    Scrape any debris or gasket remnants from the mounting surfaces with a putty knife or similar tool. Wipe the surfaces with brake cleaner applied to a clean, dry cloth.

  2. 2

    Apply a thin, continuous bead of RTV sealant to one mounting surface. Push the two mounting surfaces together before the sealant has a chance to set.

  3. 3

    Let the sealant sit for 24 hours to cure. Keep even pressure on the mounting surfaces during this time to ensure an even seal.
