Tech Install Tip: Replacing a water-cooled alternator is a labor-intensive process that involves the vehicle’s cooling system. We strongly recommend performing a full coolant flush and replacing the Alternator Drive Belt (07C903137A) during installation. Ensure the round plug connector (L-DFM) is securely seated to prevent dashboard warning lights.
