Installation Procedure

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean all sealing surfaces.
  2. Spray Low LOC brake cleaner on the LCE sealing surface and wipe off with a clean shop towel. Avoided touching the surface after cleaning and air dry with shop air.
  3. Wipe the positive crankcase oil separator cover sealing surface with the Adhesion Plastic Pan Primer Promoter with a clean shop towel. Allow the cleaner to flash / evaporate. Wipe off the sealing surfaces with a lint free cloth. Do not touch the sealing surface after cleaning to avoid inducing containment debris to the bonding surface area. Adhesives, Fluids, Lubricants, and Sealers
  4. GM5020635
    NOTE:
    • The positive crankcase oil separator cover sealing surface must be free of contamination prior to applying the sealer.
    • Install and align the positive crankcase oil separator cover to engine block within 10 minutes of applying the sealer.
    • The positive crankcase oil separator cover must be fastened to final torque specification within 15 minutes of applying the sealer.
    • Ensure proper use of room temperature vulcanizing (RTV) sealant. Use of Room Temperature Vulcanizing (RTV) and Anaerobic Sealant

    Apply approximately a 4 mm (0.16 in) thick bead of sealant (1) to the positive crankcase oil separator cover. Adhesives, Fluids, Lubricants, and Sealers
