Caution: 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.
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. 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.
Visual/Physical Inspection
- Support the powertrain using the appropriate support method; refer to the powertrain mount replacement procedure. Raising the powertrain removes the weight from the engine mount and creates slight tension in the rubber.
- Clean the mount and surrounding area to ensure good visibility of the mount condition.
- Verify all attaching fasteners are present and at the correct torque. Refer to
Engine Mount Replacement - Left Side and/or
Engine Mount Replacement - Right Side for any torque sequencing and/or torque specifications.
Note: Observe the engine mount while raising the engine. If the engine mount exhibits any of the following conditions the mount may require replacement. Refer to
Engine Mount Replacement - Left Side and/or
Engine Mount Replacement - Right Side.
- Slightly raise the engine approximately 5-7 mm.
- Inspect the mount for any of the following conditions:
• | Hard rubber surfaces - covered with extreme heat check cracks. |
• | Rubber separation from the metal plate of the engine mount. |
• | Rubber is split through the center of the engine mount. |
| Note: Before replacing any engine mount due to suspected fluid loss, verify that the source of the fluid is from the engine mount , and not the engine or an external source.
|
• | If equipped with a hydraulic mount, inspect for GLYCOL™ fluid leaking from the engine mount. |
