AMERICA'S SPORTS CAR DESERVES THE BEST ALUMINUM RADIATOR UPGRADE

Corvettes do many things quite well. From hot lapping the drag strip to stretching its legs on the road course, or even taking in a cross-country road trip, the Corvette has the power, handling, braking, and comfort to handle anything you can throw at it. That is until you notice the temp gauge climbing, that sweet tattle tale whiff of coolant, and steam exiting your hood gaps when the stock cooling system is overwhelmed by aftermarket high performance upgrades.

With the radiator design GM used on the C7 Corvette, like many designs on the road today, product costs and installation methods on the assembly line dictate the product and its compromises. An aluminum radiator core with injection molded plastic end tanks that are crimped to the core, sealed with a giant O-ring, means Chevrolet's Corvette befalls the same issues as most vehicles using a similar radiator design when asked to do more that it was designed for.

While this design saves weight and allows mounts to be molded into the tank, saving the cost of additional bracketry to secure the radiator, the vibration felt throughout the chassis from powerful engine upgrades and extended hard driving puts a lot of strain on these mounting points, creating cracks, and the harmonics/twisting motion creates leaks at the crimping point of the plastic end tanks. A lack of cooling system service creates failure points too. Solve these issues with a DeWitts Direct Fit® performance aluminum C7 Corvette radiator upgrade.

BUILT TO FIT YOUR C7 CORVETTE WITH ZERO MODIFICATIONS TO INSTALL

We get it, the injection molded end tanks save money and are easy to manufacture while handling the Corvette's stock cooling needs, but that's not how we do things with DeWitts radiators. Our Pro Series Direct Fit® C7 Corvette radiator upgrade 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 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 end tanks mean you won't have any fitment issues and your factory cooling hoses, oil cooler lines, fan shroud, and more will all connect right up without modification. Flat plate welded end tanks that our competitors use rarely have this luxury, requiring modifications to your car to fit the larger tanks and/or additional bracketry or adapters to refit your stock components. Using a two-row core built with 1-inch-wide dimpled core tubes, which create turbulence versus a smooth tube, increases heat transfer to the serpentine cooling fins. These cooling fins maximize air flow contact through the core to pull away the most heat, no matter the demand on the system, while the dual 1-inch tubes increase coolant capacity by one gallon over the stock single row core. Our Black Ice two-part epoxy coating is a semi-gloss black finish that provides an OE-like look for those that want to keep things low key under the hood.
