NUMBER: 24-02-99

GROUP: Heating & A/C

DATE: Jan. 29, 1999

SUBJECT:
A/C Compressor Service

MODELS:
1999 (WJ) Grand Cherokee





DISCUSSION:
When service requiring the removal of the A/C compressor is performed, care must be used when installing the lower compressor mounting bolt (See Figure 1). The torque specification on this bolt is 54 Nm (40 ft. Lbs.). Excessive tightening of the bolt can damage the engine block. Do not use impact tools in this area.

A new bolt has been released which has a break away feature incorporated to protect the engine block. This bolt, p/n 53013390AA, should be installed any time the A/C compressor is serviced.
