DeWitts Radiator now offers Direct Fit® aluminum radiators for your classic Chevelle. DeWitts Radiator established its reputation by providing Corvette owners high performance aluminum radiators that fit the factory mounting. We named our line of radiators “Direct Fit®” because that’s exactly what they are. We control 100% of the manufacturing process in house, including our own aluminum brazing furnace. The quality of the radiator is only as good as the core and this is the key to why DeWitts radiators are superior in performance. Our confidence in our brazing process and quality is expressed by our LIFETIME WARRANTY.
