Keep Your 68-72 GM A-Body Cool Using Our WindChill® Crossflow Aluminum Radiator Kit

The stock GM A-body radiators found in GM’s midsize car line (Chevelle, GTO, Skylark, Cutlass, etc.) were your typical copper/brass construction with two rows of cooling within the core. These Chevy muscle car radiators handled standard production engine cooling with ease, but once owners started turning up the performance dial cooling issues often reared their ugly head, causing overheating or other cooling system issues. Like any performance V8, the small block Chevy engine requires a properly sized radiator for 350 Chevy engines to adequately control the engine’s thermal needs.

Once you begin upping compression, adding timing, and bolting on performance parts, the stock cooling system cannot keep up with the engine’s thermal demands. Adding a larger aftermarket aluminum radiator isn’t always physically possible, so going with additional cores is your best option to rein in those engine temps. Our WindChill® 3-core direct fit aluminum performance radiator for small block Chevy powered 68-72 GM A-Body cars (and big-blocks too!) takes the guesswork out of building the proper cooling system for your C10 build. It is designed to work and fit perfectly with the OEM saddle mounting system and OEM-spec upper and lower cooling system hoses and includes a built-in automatic transmission cooler, just like the original.

Three Row Core for Increased Thermal Transfer and Greater Coolant Capacity

If the stock two rows of 1-inch cooling tubes are good, three rows of cooling tubes are better, right? Not always, but it can be. Just adding a third row or “core” to a two core radiator can often increase the thickness of the Chevelle radiator core to the point there are fitment issues in the vehicle, or the core thickness becomes too much for the typical electric or engine driven fan to pull air through, negating the benefit of the additional core tube. Our WindChill® three core GM A-Body radiators use .790-inch core tubes, so our three row Chevelle aluminum radiator is only 7/16-inch thicker yet has a 17 percent increase in coolant capacity. The additional coolant tube in our three row radiators also provides more thermal transfer to the cooling fins that surround the core tubes, providing better cooling with minimal additional core thickness. It is the best solution for increased coolant capacity and thermal transfer efficiency without causing fitment issues in most installations.

Crafted from aluminum with stamped and dimple reinforced end tanks for the best heat transfer and the lightest weight, our 3-core aluminum performance radiator for small block Chevy powered 68-72 GM A-Body vehicles are completely furnace brazed for a long life in your GM muscle car. No epoxy to crack and fail, no O-ring gasketed end tanks to leak. Just quality build construction that will last. Utilizing a single pass 3-row radiator crossflow design, each SBC 68-72 A-Body Chevelle aluminum radiator is ready for your GM V8-powered A-Body cooling system needs (including big blocks!) with correct 68-72 GM V8 specific inlet and outlet radiator hose fittings, sized at 1.50-inch at the upper left and 1.75-inch at the lower right respectively, along with a 3/8-inch NPT temperature sensor/switch port. Top and bottom hat channel rails allow installation of most electric fan/shroud packages. Additionally, a standard internal stacked plate style transmission cooler is included and connects to your transmission cooler lines via 1/2-20 inverted flare fittings or can be converted to AN -6 fittings for use with aftermarket AN transmission cooler line kits.

Our WindChill® 68-72 Chevelle radiator kit features a precision fit aluminum fan shroud that covers the entire core for maximum airflow through the radiator. The shroud mounts a pair of 12-inch 1,000 cfm fans (fan and shroud mounting hardware included) to ensure your GM A-Body stays cool during extended idling/low speed cruising. The GM A-Body aluminum radiator with fans can be controlled via your aftermarket EFI, a manual switch, or one of our cooling fan controller options. Lastly, our WindChill® 68-72 Chevelle radiator features a strong billet aluminum radiator neck that utilizes industry standard 1-5/8-inch radiator caps and includes a pre-installed 5/16-inch hose barb fitting for use with an overflow tank of your choice to help you create the right small block Chevy cooling system for your 68-72 GM A-Body muscle car project.
