Installation Notes and Tips
Verify pulley groove count, rotation direction, plug clock position, and mounting-ear orientation before installation. This AL4322X uses a rear-view main mounting ear position at 6 o’clock and a 5 o’clock plug clock reference, so matching the original unit is important for proper fitment. Confirm belt alignment and charging-system connections during replacement.
