Cool Your C7 Corvette in the Harshest of Track Environments

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.

Adding a DeWitt’s Direct-Fit® radiator is certainly a step in the right direction for your 2014-2019 C7 Corvette. However, if you really like to push your C7’s engine hard you may have encountered the dreaded coolant fault triggering in the ECM, which engages “limp mode,” causing reduced engine performance until the car has cooled to a sufficient temperature. Adding our C7 Corvette Auxiliary Radiator to your Corvette’s cooling system you provide extra capacity and extra cooling that will keep overheating during extended rpm use at bay and keep you on track.

Built Just Like Our C7 Corvette Radiators for Optimum Efficiency

We use a single row 1.5-inch core material similar in design to our C7 DeWitts radiator that helps them to work so well. The 1.5-inch wide core tubes are sandwiched between our serpentine cooling fins for maximum heat transfer to the air flowing through the auxiliary radiator’s core. Our C7 Corvette Auxiliary Radiator is sized to provide maximum surface area while fitting within the confines of the factory duct assembly. The additional core area not only offers more surface area for cooling but provides an increase in coolant capacity as well.

Bolt In Installation You Can Handle Before Your Next Track Day

We make installation easy with full color instructions along with a true to scale template for the plastic material that must be trimmed to mount the auxiliary radiator in place. This template provides proper location of all mounting holes as well, which take a basic 1/4-inch drill bit to create. Our C7 Corvette’s auxiliary radiator kit is complete down to the hose clamps and mounting hardware. Even the heater hose provided to connect our auxiliary radiator between the engine’s oil cooler outlet and main radiator inlet is already pre-cut to length, making this install frustration free!
