Product Details

CSF manufactures radiators to high-performance standards and validates cooling performance through wind tunnel testing. The 3615 follows an OEM-style plastic tank and aluminum core construction, making it a direct-fit replacement for vehicles that require factory-style hose routing and cooling system geometry. This part number 3615 is listed for 2010-2018 Hyundai Santa Fe, 2013-2019 Hyundai Santa Fe XL, 2013-2018 Hyundai Santa Fe Sport, and 2011-2015 Kia Sorento applications, with a separate 2010-2012 Hyundai Santa Fe listing for automatic air conditioning.

CSF’s broad radiator catalog and long production history support consistent fitment coverage across many late-model import vehicles. This radiator cross-references Spectra Premium CU13191 and CU13194 for the same application.

What This Radiator Helps Address

• Engine overheating caused by a leaking or restricted radiator
• Coolant loss from cracked plastic tanks or aged core joints
• Reduced heat transfer from a clogged or corroded cooling core
• Factory-style replacement needs after radiator failure
• Cooling system service on Hyundai Santa Fe and Kia Sorento models

Installation Notes and Tips

• Verify inlet and outlet orientation before installation: right inlet, left outlet.
• Confirm vehicle configuration, especially automatic air conditioning on 2010-2012 Hyundai Santa Fe models.
• Inspect hoses, clamps, and coolant condition before installing the new radiator.
• Use the correct cap specification for this application; cap is not included.
