Product Details

CSF’s 1 Row Plastic Tank Aluminum Core line focuses on OE-style replacement radiators built to match factory-style packaging and cooling layout. The CSF 3401 follows that approach with a 28 11/16 in. core width, 15 13/16 in. core length, and a 5/8 in. core thickness for the Honda Element platform. CSF states that its radiators are manufactured to performance standards, validated through wind tunnel testing, and produced in ISO/TSO-certified facilities. This radiator is a direct-fit solution for Honda Element cooling system service and is listed with the same application across 2007, 2008, 2009, 2010, and 2011 models.

This part cross-references Spectra Premium CU13015 for the same application.

Common Cooling System Issues It Can Address

  • Coolant leaks from a cracked or aging radiator tank
  • Restricted coolant flow from internal corrosion or sediment buildup
  • Overheating caused by reduced heat transfer efficiency
  • Transmission or engine oil cooling concerns on equipped vehicles
  • Replacement needs after impact damage or seam failure

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this unit uses a 1 1/4 in. left inlet and 1 1/4 in. right outlet. The application note specifies use with a Micro, 16 psi cap, and the radiator does not include a cap. Confirm hose condition, inspect mounting points, and flush the cooling system before installing a new radiator to help protect the replacement unit and maintain proper flow.

Quality Assurance

CSF manufactures radiators for a wide range of vehicle applications and reports more than 30 million units sold worldwide. The brand also notes ISO/TSO-certified production and laboratory testing for cooling performance validation.
