Engine Mount Inspection

IMPORTANTBefore replacing any engine mount due to suspected fluid loss, verify that the source of the fluid is the engine mount, not the engine or accessories.
  1. Install a engine hoist to the lift brackets and raise the engine slightly putting pressure on the engine mounts.
  2. Observe the engine mount while slightly lifting the engine. Lifting the engine removes the weight from the engine mount and creates slight tension on the rubber.
  3. Replace the engine mount if the engine mount exhibits any of the following conditions: The hard rubber is covered with heat check cracks. The rubber is separated from the metal plate of the engine mount. The rubber is split through the center of the engine mount. The engine mount is leaking fluid, if applicable.
  4. For engine mount replacement, refer to «Engine Mount Replacement»(/buick/regal/v-2009-2013/remont/mechanical/#engine-mechanical-20l-repair-instructions-on-vehicle) .
