    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.

    NOTE:

    Work through the front wheelhouse opening to access the 3 engine mount frame side bolts (1).

    If NEW threaded components are being installed, loosen the adhesive using a metal pick or similar tool before proceeding. If threaded components are reused, prepare the threaded components using the following steps:

    1. Remove any loose cured adhesive from the external threads of the components using a lint free cloth.
    2. Thread the cleaned components into the internal mating threads and remove to loosen trapped cured adhesive.
    3. Apply thread locking adhesive to the external threads of the components. Adhesives, Fluids, Lubricants, and Sealers
    4. Ensure there are no gaps in the thread locking adhesive once applied to the component.
  8. Engine Mount Frame Side Bolt- Right Side (1) - Install and hand tighten [ 3x ]
  9. Engine Mount Frame Side Bolt- Right Side (1) - Tighten in sequence [ 3x ] - Fastener Specifications
