To prevent the alternator bolt from becoming loose and breaking, the
torque specification has been increased.

The increased torque specification requires use of a new bolt on 1.9L
water cooled engines.

To repair a loose/broken bolt:
1.9L Gas Engine
* Install new bolt, Part Number  N 014 400 4.
  Torque to 25Nm (18 ft. lb.).

Diesel Engine
* Replace bolt only if damaged, Part Number is unchanged.
  Torque to 28-33Nm (21-24 ft. lb.).
