Installation Notes and Tips

Verify the connector clocking, mounting ear position, pulley style, and rotation direction before installation. This unit uses a rear-view plug clock of 9 o’clock with the main mounting ear at 6 o’clock, so matching the original alternator configuration is important for proper fitment. Confirm serpentine belt alignment and inspect the belt and tensioner during replacement on BMW 740i and BMW 740Li models.
