A full-aluminum, TIG-welded performance radiator for the 2017-2019 Chevrolet/GMC 6.6L L5P Duramax, replacing the failure-prone plastic-tank factory unit. The redesigned core delivers a 25-percent increase in coolant capacity and a 14-percent increase in total core volume for greater heat dissipation. A Mishimoto magnetic drain plug is included to capture metallic debris from the coolant. Fits L5P-equipped trucks with minor trimming of the factory fan shroud to clear the thicker core.
