Detailed Description

CSF 3880 is a replacement radiator engineered for OE-style fitment in select Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. The aluminum core and plastic tank construction follows the factory-style layout, while the cross-flow, single-row design supports efficient coolant transfer through the radiator assembly. CSF states its radiators are engineered and wind-tunnel tested for cooling performance validation, and the brand has manufactured radiators for decades across a wide range of vehicle applications.

This radiator cross-references CSF 3880 for the same application and is listed with interchange references 23388802, 84301712, and GM3010612. It is a direct-fit style replacement for trucks that require the specified inlet, outlet, and oil cooler configuration.

Installation Notes and Tips

Verify the vehicle’s cooling package before ordering, since fitment differs between 2019-2020 models with Max Trailering Package and 2021-2024 models without Max Trailering Package. Confirm inlet and outlet orientation, core dimensions, and oil cooler configuration against the original radiator before installation. Transfer any required vehicle-specific components from the original assembly as needed.

CSF manufactures radiators to high-performance standards in ISO/TSO-certified facilities and validates designs through laboratory testing for cooling performance. Part number 3880 is built as an OE-style replacement for consistent fitment on the listed Chevrolet Silverado 1500 and GMC Sierra 1500 applications.
