Radiator, HE Core, 1973-77 GM Truck/SUB/Blazer/Jimmy, 6Cyl, w/Factory 2" Core

1973–77 Chevrolet & GMC Truck High-Efficiency Radiator by US Radiator®

Closely spaced cooling tubes with a factory-style black finish.

Replace the radiator in your 1973–77 Chevrolet & GMC Truck with a US Radiator® copper-and-brass assembly. The application-specific core distinguishes this configuration from similar-looking radiators. Its configuration includes 26-1/4-inch-wide core; 2-3/4-inch mounts. Its high-efficiency core places the tubes closer together than a standard core for additional heat-transfer surface. Match the core size, mounting arrangement and engine application to your original unit. Manual- and automatic-transmission versions are offered; select the automatic version when a built-in transmission cooler is needed.
