Chevrolet Silverado 1500 Radiator - Mishimoto - Alum - `03-`05 is a direct-fit aluminum replacement for 2003–2005 Silverado 1500 trucks. Designed to replace worn or leaking stock units, it restores dependable cooling performance for daily driving and light towing.

This unit is a good choice when a radiator shows leaks, reduced flow, or cracked components; consult the application guide for exact fitment details.
