Radiator w/Fans Nova LS 73-74 Auto Trans Raw

The DeWitts Radiator with Fans Nova LS 73-74 Auto Trans Raw is a purpose-built aluminum cooling solution engineered for LSX engine conversions into 1973–1974 Chevrolet X-Body vehicles. This radiator delivers efficient heat rejection for automatic transmission applications, combining modern aluminum construction with a raw finish that integrates seamlessly into classic restoration and performance build scenarios.

Measuring 24 inches wide by 37 inches tall with a 9-inch depth, this radiator is sized to fit original Nova engine bays while accommodating the larger displacement and cooling demands of an LSX conversion. The passenger-side inlet and outlet configuration allows flexible plumbing routing within tight engine compartment layouts. Integrated electric fans provide reliable thermostat-controlled cooling, eliminating the parasitic load of belt-driven mechanical fans and freeing horsepower while improving idle quality and underhood temperatures during traffic or high-load driving.

This kit is purpose-designed for LSX Nova conversions—the popular restomod platform that pairs second-generation Chevy X-Body chassis with modern LS or LSX engines. Builders choosing this radiator solution are typically targeting reliable temperature control without frame-mounted radiators or extensive custom fabrication. The automatic transmission specification ensures the cooler circuit accommodates fluid cooling requirements, preventing thermal degradation under sustained driving or performance use.

DeWitts is established in the performance cooling market for aluminum radiator and fan systems that serve the engine swap and restoration communities. The raw aluminum finish allows finishes to be applied during final assembly, giving builders flexibility in appearance while maintaining the structural and thermal integrity required for modern engine conversions into classic platforms.
