Product Details

CSF designs and manufactures radiators to high-performance standards using ISO/TSO-certified factory processes and lab validation methods, including wind tunnel testing for cooling performance. The CSF 3477 follows an OEM-style layout for the Acura RDX and uses plastic end tanks with an aluminum core to match the original cooling system architecture. This radiator is a direct-fit replacement for 2007, 2008, 2009, 2010, 2011, and 2012 Acura RDX models, and the CSF 3477 is built for vehicles that require the OE-style plastic tank aluminum core configuration.

This part cross-references APDI 8012916 and Spectra Premium CU2916 for the same application.

Common Cooling Issues Addressed

  • Cracked or leaking radiator tanks
  • Restricted coolant flow from an aging core
  • Overheating caused by reduced heat transfer
  • Oil cooler wear in integrated cooling systems
  • Fitment problems from damaged OE-style radiator assemblies

Installation Notes and Tips

Verify the vehicle uses the OE-style plastic tank and aluminum core layout before installation. Confirm inlet and outlet orientation, left-side connection points, and cap requirements; this radiator does not include a cap. Inspect hoses, clamps, and the cooling system for wear before installing the CSF 3477 to help ensure proper sealing and coolant circulation on Acura RDX models.

Quality Assurance

CSF manufactures radiators in ISO/TSO-certified facilities and validates cooling performance through engineering and testing processes. The brand has supplied radiators worldwide for decades and offers a broad catalog of radiator applications across many vehicle platforms.
