Preparation

  1. Park vehicle on level surface and engage parking brake
  2. Disconnect negative battery cable
  3. Raise front of vehicle and support on jack stands at frame rails
  4. Remove engine skid plate or belly pan if equipped
  5. Spray all mount bolts with penetrating oil and allow to soak
  6. Install engine support bar across inner fenders or position overhead hoist with load leveler
  7. Take weight off engine mounts by slightly lifting engine with support equipment

Procedure

  1. 1
    Support engine weight
    Using engine support bar or overhead hoist, lift engine approximately 1/4 inch to unload all mounts. Engine should be stable and level. Verify engine does not contact firewall or radiator support. Adjust as needed to maintain clearance.
    ⚠️Ensure support equipment is properly positioned and locked before proceeding. Engine must not shift during mount replacement.
