Engine all (4xWD, CAR, Heavy transporter, Light transporter, smart) 

1. Remove operating fluids and other soiling from the sealing surface with a lint-free dry cloth.
2. Adhesive and sealant remover Spray Loctite 7200 onto the sealing surfaces and leave for approx. 10 to 20 minutes.

   Only cleaning with the approved adhesive and sealant remover is permitted.

   Observe processing information from manufacturer.

3. Remove dissolved silicone sealant from the sealing surfaces and wipe with a lint-free dry cloth.

   Do not use sharp-edged tools or abrasive paper.

   Otherwise, damage to the sealing surfaces and then engine and environmental damage may result.

   Mechanically processing or cleaning the sealing surfaces, spot grinding with abrasive paper or other abrasive materials to remove seal residue is not permitted.

   Even small amounts of aluminum oxide particles, particles produced during grinding or wear debris entering the engine oil compartment, the bearing points or the combustion chambers will cause damage thus engine damage.

   The sealing surfaces must feel even after treatment. The sealing surfaces do not have to be metallically bright; thin layers of firmly adhering silicone sealant may remain (see picture).

4. Thoroughly clean the sealing surfaces with Loctite 7063 cleaning spray and blow them off with compressed air.

   Allow Loctite 7063 cleaning spray to flash off completely before applying new silicone sealant.

   Leaks can occur otherwise.
