Removal Procedure


    Object Number: 1202885  Size: SH

    Caution: Broken engine mountings can cause misalignment of certain drive-train components. Misalignment of drive-train components causes eventual destruction of the drive-train components.

    If one engine mount breaks, the rest of the engine mounts will have increased stress put on them. This could cause the rest of the engine mounts to break.

  1. Install the EN46567  (1).
  2. Remove the air inlet grill panel weatherstrip.
  3. Remove the exhaust manifold heat shield.
  4. Caution: When raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal, or crankshaft balancer. Jacking against the oil pan may cause it to crack or break.

  5. Position the EN46567  (1) on the air inlet grill panel and the front upper panel on the center.
