Front Engine Mount

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Broken or deteriorated mounts can cause misalignment and destruction of certain drive train components. When a single mount breaks, the remaining mounts are subjected to abnormally high stresses.

NOTE: When raising or supporting the engine for any reason, do not use a jack under the oil pan, any sheet metal, or the crankshaft pulley. Due to the small clearance between the oil pan and the oil pump screen, jacking against the oil pan may cause the pan to be bent against the pump screen. This will result in a damaged oil pickup unit.

Raise the engine in order to remove the weight from the mount and to place a slight tension on the rubber cushion.
Use a jack on the square tab at the rear of the engine block. Observe both mounts while raising the engine.

Replace the mount if any of the following conditions exist:
- Hard rubber surface covered with heat check cracks
- The rubber cushion separated from the metal plate of the mount
- The rubber cushion is split through the center
If there is movement between a metal plate of the mount and its attaching points, lower the engine and tighten the bolts or nuts attaching the mount to the engine, the frame or the bracket.
