Removal Procedure

WARNING: This page is about a different car, the 2003 GMC Savana and 2003 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
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. Raise and support the vehicle.
  2. Remove the engine mount to frame mounting bolts.

    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.

    Important:  Raise the engine only enough to permit removal of the engine mount.

  3. Use a jack on the square tab at the rear of the engine block, and raise the engine, left side shown.
