Detailed Product Overview

This radiator is engineered for cooling-system replacement on the 2002-2004 Pontiac Grand Am, 2002-2004 Oldsmobile Alero, and 2002-2003 Chevrolet Malibu.

Installation Notes and Tips

Verify heater hose routing, cooler line connections, and mounting points before installation. Flush the cooling system, inspect hoses and clamps, and transfer any reusable components as needed.
