Installation Notes and Tips

Verify the vehicle’s original alternator matches the listed 70 amp Bosch-style configuration before installation. Confirm pulley transfer requirements, belt alignment, connector style, and mounting points against the removed unit. Because this alternator is supplied without a pulley, reuse or source the correct pulley for the application as needed. Check charging voltage after installation to confirm proper system operation.
