Mishimoto Performance Aluminum Radiator - Chevrolet Corvette (C5) 1997-2004

The Mishimoto performance radiator for the LS1 and LS6 C5 Corvette uses a 2.2 in thick brazed aluminum core, more than double the factory thickness, for 134% more cooling capacity than stock. TIG-welded aluminum end tanks replace the crack-prone factory tanks, and an enlarged in-tank transmission cooler lowers fluid temperatures under hard use. Transmission line adapters for every C5 model year, mounting grommets, and seals are included.
