Detailed Description

CSF Part Number 3727 is a radiator assembly designed around OE-style fitment and cooling layout. The aluminum core and plastic tank construction follows the factory-style design used on 2013-2021 Buick Encore and 2015-2020 Chevrolet Trax applications, with a 2021 Chevrolet Trax listing also confirmed. CSF manufactures radiators to controlled performance standards and validates cooling performance through laboratory wind tunnel testing. This radiator includes an integrated high-efficiency plate-type oil cooler and uses quick-connect fittings for the outlet pipe and oil cooler connections.

This part cross-references Monroe Shocks & Struts (e.g., 95298552, GM3010562) for the same application.
