Mishimoto 55-57 Chevrolet Bel-Air Inline 6 X-Line Aluminum Radiator

If you're looking to upgrade your 1955--1957 parts, look no further! The Mishimoto 1955--1957 Chevrolet Bel Air X-Line Performance Aluminum Radiator provides your car with enhanced reliability, improved cooling efficiency, and is an ideal upgrade for the brittle stock radiator. Whether you use your classic for daily driving or take it to the track, many people overlook the importance of installing an upgraded radiator in their engine. A stock radiator cannot handle the heat that comes along with having a great deal of horsepower. The Mishimoto Chevrolet Bel Air X-Line Aluminum Radiator is manufactured using durable aircraft-quality aluminum end tanks, precision TIG-welded to an efficient brazed aluminum core. The inlet and outlet provide precise leak-free connections. This Chevy Bel Air performance radiator also includes a Magnetic Oil Drain Plug, which effectively removes metal fragments circulating in the cooling system. As with all our aluminum radiators, this Chevy Bel Air radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
