Front Engine Mount

WARNING: This page is about a different car, the 2003 GMC Envoy XL and 2003 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.

Install a pole jack underneath the oil pan.
Insert a block of wood between the engine oil pan and the pole jack.
Raise the jack until the wooden block contacts the engine oil pan.
Raise the engine in order to place a slight tension on the rubber cushion. Observe both mounts while raising the engine.
Replace the mounts 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
- The mount is leaking

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.
