Engine Mount Inspection

WARNING: This page is about a different variant/trim than selected.
    NOTE:

    Before 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 the engine support fixture. Refer to Engine Support Fixture . Raising the engine removes the weight from the engine mount and creates slight tension in the rubber.
  2. Observe the engine mount while raising the engine. Replace the engine mount if the engine mount exhibits any of the following conditions:
    • The hard rubber surface is covered with heat check cracks.
    • The rubber is split through the center of the engine mount.
    • The GLYCOL™ fluid is leaking from the engine mount.
  3. Inspect the system for loose vacuum hose connections or vacuum leaks. Refer to Vacuum Operated Engine Mounts Description and Operation.
  4. Inspect the engine mount valve assemblies for loose electrical connections. Inspect the electrical system connected to the engine mount valve assemblies. Refer to Diagnostic System Check - Vehicle .
  5. Inspect for the presence of glycol fluid in the vacuum system. Remove the hose assembly connections at the engine mounts. If fluid is present in the engine mount vacuum system, the entire vacuum system should be replaced.
