Detailed Description

Part number 13029E is an OSC Premium new automotive radiator engineered for multi-fit coverage without changing the look or fit of the original cooling system. It includes plated cooler sections, a die-cut gasket for leak resistance, and factory-spec fitted components. The radiator is built to meet OES cooler design requirements where the original application used copper concentric or plate coolers, making it a strong match for GM truck and SUV cooling system service.

Installation Notes and Tips

Verify the radiator dimensions, inlet and outlet sizes, and cooler configuration before installation. This unit is built for economy-version applications, so matching the original cooling package is important for proper fit and function. Part number 13029E includes the necessary fittings or hardware referenced by the manufacturer.

Quality Assurance

OSC states that each radiator is individually pressure tested during production and built to OES form and function standards. The design uses cadmium-plated tubes and factory-spec component placement to support consistent sealing and cooling performance.
