Heat from exhaust pipe may cause right side hydraulic engine mount to become ineffective. This results in excessive engine vibration.
Factory has introduced two production modifications as of May 13,1983, VIN 94 DN 462115
Right front louver of lower engine cover has been reversed for better air intake.
Engine mount heatshield is now louvered for additional cooling.
If engine mount failure occurs on vehicle produced after VIN 94 DN 462115, make following modification when replacing mount:
- insert washer (N015 401 3) between support bracket and engine mount:
- do this at both mounting bolts
- torque bolts to 23 N-m (17 lb ft)
Inserting washer creates air gap between engine mount and support bracket. This improves cooling at mount.
If engine mount failure occurs on vehicle produced prior to VIN 94 DN 462115, Make following modifications:

- raise vehicle
- remove lower engine cover
- place cover on suitable support (wooden blocks)
