Engine Mount Inspection
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.
- Raise the vehicle.
- Inspect for loose or missing bolts at the following locations:
- The engine mount bracket to the engine.
- The engine mount to the frame.
- Replace loose or missing bolts. Refer to the following procedures:
- Remove the starter, when checking the right side only. Refer to STARTER MOTOR REPLACEMENT (4.3L)
or STARTER MOTOR REPLACEMENT (4.8L, 5.3L & 6.0L)
.CAUTION: 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. Lifting the engine in an unapproved manner may cause component damage.
- Using a jack on the square tab at the rear of the engine block raise the engine in order to complete the following tasks:
- Remove weight from the engine mount.
- Place a slight tension on the rubber cushion.
- Observe the engine mount while raising the engine.
- Replace the engine mount if the following conditions exist:
- Heat check cracks cover the hard rubber surface.
- The rubber cushion is separated from the metal plate of the engine mount.
- There is a split through the rubber cushion.
- Lower the vehicle.
