Inspect
NOTE
Although the following procedure provides
information regarding on-vehicle engine mount
inspections, it is preferable to inspect the engine
mounts once removed from the vehicle.
1 Fit the engine lift brackets, Tool No. EN-4611 to the cylinder heads.

Only lift the engine enough to take the weight
off the engine mounts, or damage to the
mounts and lifting equipment failure may
occur.
2 Using a commercially available engine lifting crane, have an assistant raise the engine far enough to remove the weight on the engine mounts and create a slight tension in the rubber.
3 Observe the engine mount while raising the engine.

4 Replace the engine mount if any of the following conditions are found:
