Make Sure Your C10 Keeps Its Cool No Matter What You’re Hauling
The General Motors C10 line of full size pickup trucks have a strong and loyal following. As GM’s direct competitor to Ford’s F-series pickups and Dodge’s D-series pickups, they were used for many things throughout lengthy ownerships. From hauling materials, pulling trailers, and handling duties on the farm or out in the field, to being a rugged and ready second vehicle for the family, these C-series trucks have certainly left their mark. Today they are popular foundations for everything from award winning show vehicles to auto crossers, to drag racers. No matter what your first generation C-10 does today for you, keeping its engine running at the proper temperature is critical.
Designed to Fit Your 1963-1966 C10 Truck with Zero Modifications to Install
Our Pro Series Direct Fit® C10 aluminum radiator is built using the highest quality aluminum materials, assembled, furnace brazed, and TIG welded all in our Wixom, Michigan facility (just 30 mins up I-96 from GM’s corporate headquarters at the Renaissance Center). Each custom aluminum radiator carries a limited lifetime warranty, is pressure tested, and carefully double wall boxed with insulation to ensure it makes the trip to you and keeps your project moving forward.
Our press formed top and bottom tanks provide an OE appearance and mean you won’t have any fitment issues. Flat plate welded tanks that our competitors use rarely have this luxury, requiring modifications to your truck’s core support or replacing the C10 radiator brackets to fit the larger tanks. Using a two-row core built with 1-inch-wide core tubes and serpentine cooling fins (which is equivalent to a four-core copper/brass radiator) maximizes air flow contact through the core to pull away the most heat, no matter the demand on the system.
Our Direct Fit® C10 radiator allows you to easily bolt in the best aluminum radiator for your 1963-1966 C10 project. Not only is our downflow radiator design a hassle-free install but we have properly fitted our high performance radiator with the correctly located inlet and outlet radiator hose fittings at a total weight of just 16 pounds. A pair of SPAL 11-inch cooling fans with pre-installed coolant temperature sensor and complete wiring harness is available as an option. Automatic transmission-equipped models feature an internal cooler in the bottom tank that accepts stock transmission cooler line fittings. Our Black Ice two-part epoxy coating option is a semi-gloss black finish that provides an OE-like look for those that want to keep things low key under the hood.
C10 Pickup Pro Series Direct Fit® Radiator Options
We offer Direct Fit® C10 truck radiators for the first three generations of C10 trucks, as well as LS swap radiators for 1963-1987 C10 pickups for those that have dropped in GM’s latest small block. The optional SPAL dual 11-inch cooling fan solution, rated at 2,720 cfm, comes preinstalled to the radiator core when ordered, as does the fan’s temperature sensor. A complete fan wiring harness is included with a relay for each fan. We recommend one of our DeWitts logo billet 15 psi radiator caps to finish off your new high performance radiator installation. Finally, be sure to add some DeWitts High Performance coolant to your order to protect your cooling system and help it achieve maximum thermal capabilities.
