Mishimoto’s X-Line radiator for 1967–1972 GM C/K trucks replaces the original with an all-aluminum unit to improve cooling and reliability. The design uses aircraft-quality aluminum end tanks TIG-welded to a brazed 3-row core, increasing coolant capacity and heat dissipation. Inlet and outlet fittings provide precise, leak-free connections for classic truck cooling systems.
