Product Details

CSF 3605 is part of the brand’s 1 Row Plastic Tank Aluminum Core line, a product line focused on OE-style radiator construction for everyday replacement needs. The aluminum core helps transfer heat efficiently, while the plastic tanks match the factory-style layout used on the listed vehicles. CSF manufactures a wide range of radiator applications and validates cooling performance through lab testing, with production backed by ISO/TSO-certified factories.

Compatible With 2013-2017 Honda Accord and 2015-2020 Acura TLX, this radiator is a direct replacement for vehicles that require the specified down-flow configuration and left-side inlet/outlet layout. Part number 3605 also cross-references APDI 8013363 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 dissipation
  • Corrosion or wear in the original radiator assembly
  • Factory radiator replacement after collision or service damage

Installation Notes

Verify radiator dimensions, inlet and outlet orientation, and down-flow configuration before installation. This unit uses a micro, 16 psi cap specification for the listed applications, and the cap is not included. Confirm hose routing and mounting points against the original radiator to ensure proper fitment on your Honda Accord or Acura TLX.

Quality Assurance

CSF radiators are manufactured in ISO/TSO-certified facilities and built to high-performance standards. The brand has supplied radiators worldwide for more than 50 years and uses engineering and wind-tunnel testing to validate cooling performance across its radiator catalog.
