Detailed Product Overview

Denso supplies radiators to original equipment vehicle manufacturers worldwide, and this radiator reflects that OE engineering approach. The core size, tank layout, fin pitch, and materials are built to meet strict manufacturer standards, helping maintain proper engine temperature control in Mitsubishi Eclipse models from 2006 through 2011. If you are replacing a worn or leaking radiator on a Mitsubishi Eclipse, the Denso 221-9174 offers the correct fitment profile for cooling system service.

This part cross-references Mitsubishi (e.g., MN180281) for the same application.

What This Radiator Helps Address

• Coolant leaks from a damaged or corroded radiator
• Overheating caused by restricted heat transfer
• Transmission cooling concerns when the radiator cooler circuit is compromised
• Fitment issues from using the wrong core size or hose connection diameter
• Cooling system service on a 2006-2011 Mitsubishi Eclipse

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and transmission cooler routing before installation. Flush the cooling system, inspect hoses and clamps, and confirm all connections are clean before fitting the new radiator. After installation, refill with the correct coolant mixture and bleed air from the system according to the vehicle service procedure.

Quality Assurance

Denso radiators are manufactured to OE-level specifications and undergo durability and function testing before release. That testing process supports consistent cooling performance and fitment for Mitsubishi Eclipse radiator replacement service.
