Installation Notes and Tips

Verify the plug type, pulley groove count, rotation direction, and mounting-ear orientation against the original alternator before installation. Confirm that the vehicle is a 2002-2006 Mazda MPV and compare the existing unit to Bosch AL4236X, especially if the charging system has been previously serviced or modified.

Because this alternator uses an internal regulator and a specific 341 plug configuration, matching the original electrical connection is important for proper operation. Inspect the belt condition and charging-system wiring during replacement to help avoid repeat failures.
