Installation Notes

Verify the vehicle’s original alternator uses a 170-amp Nippondenso-style setup, a 6-groove serpentine pulley, clockwise rotation, and the 1 o’clock plug position before ordering. Confirm fitment by year, make, model, and charging-system configuration, especially on optional 170-amp applications such as 2015-2020 Chevrolet Tahoe, 2015-2020 GMC Yukon, and 2019 Cadillac Escalade models. Compare the pulley style and connector orientation to the removed unit before installation.
