Radiator, HE Core, 1978-80 GM Truck/SUB/Blazer/Jimmy, 6Cyl, 17" x 26-1/4" Core

1978–80 Chevrolet & GMC Truck High-Efficiency Radiator by US Radiator®

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

Replace the radiator in your 1978–80 Chevrolet & GMC Truck with a US Radiator® copper-and-brass assembly. The 17 × 26-1/4-inch core distinguishes this configuration from similar-looking radiators. Its configuration includes six-cylinder; narrow-core configuration. 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.
