Detailed Description

Denso 221-9575 is a radiator assembly developed to meet OE-level expectations for fitment and cooling performance. Denso uses factory-based radiator configurations, tank design, fin pitch, core sizing, and material selection to align with manufacturer standards, then subjects each radiator to durability and function testing before release. That approach supports stable cooling performance in demanding driving conditions.

This radiator fits 2016-2018 Toyota RAV4, inverter cooling, and 2015-2017 Lexus NX300h, inverter cooling. It is a strong match when replacing a worn or leaking radiator on these hybrid applications, and the part number 221-9575 is the reference to verify before ordering. This part cross-references Spectra Premium CU13614 and Toyota G9010-42020 for the same application.

What This Radiator Helps Address

• Coolant leaks from a damaged or corroded radiator core
• Overheating caused by restricted heat transfer
• Inverter cooling performance loss on hybrid applications
• Fitment issues from an incorrect replacement radiator
• Cooling system service needs on Toyota RAV4 and Lexus NX300h models

Installation Notes and Tips

Confirm the vehicle’s year, make, model, and inverter cooling configuration before installation. Compare the inlet and outlet diameters, core dimensions, and mounting layout against the original radiator to ensure proper fit. Inspect hoses, clamps, and coolant condition during replacement, and verify the cooling system is filled and bled according to factory service procedures after installation.

Quality Assurance

Denso radiators are built from OE experience and validated through strict durability and function testing. The 221-9575 follows Denso’s OE-oriented standards for performance, reliability, and fitment on the listed Toyota and Lexus applications.
