Detailed Description

Denso 221-9472 is a replacement radiator engineered to match OE manufacturer standards for configuration, tank design, fin pitch, core dimensions, and materials. For Hyundai Sonata owners, that means a radiator built around the vehicle’s cooling requirements rather than a generic universal layout. The result is a direct-fit cooling component for 2015, 2016, 2017, 2018, and 2019 Hyundai Sonata models.

Denso supplies radiators to OE car makers worldwide, and that experience is reflected in the fitment and construction of this unit. The radiator is designed to support proper heat transfer and stable engine operation, with inlet and outlet sizing that matches the listed application. If you are replacing a worn or leaking radiator on a Hyundai Sonata, part number 221-9472 provides an OE-focused solution.

This part cross-references Spectra Premium CU13457 and CSF 3755 for the same application.

Installation Notes and Tips
