Summary

BMW: ALTERNATOR DRIVE BELT BROKEN. THE MODELS UTILIZE A SINGLE SERPENTINE DRIVE BELT FOR THE POWER STEERING PUMP, ALTERNATOR, AND AIR CONDITIONER COMPRESSOR. DURING NORMAL DRIVING, THE FRONT ENGINE MOUNTS ALLOW THE ENGINE TO MOVE SLIGHTLY ON THE FRONT AXLE CARRIER. HOWEVER, UNDER EXTREME CONDITIONS, SUCH AS DRIVING AT HIGH RATES OF SPEED OVER CURBS OR SPEED BUMPS, THE ENGINE MOVEMENT CAN RESULT IN THE SERPENTINE BELT OR POWER STEERING PUMP PULLEY CONTACTING THE FRONT ENGINE CARRIER. IF THIS OCCURS, THE BELT AND/OR PUMP PULLEY COULD BE DAMAGED. NO MODEL YEARS LISTED. *PE
