Detailed Description

Denso part number 221-9222 is a direct-fit radiator for the 2006-2009 Honda S2000. Denso supplies radiators to original equipment vehicle manufacturers worldwide, and this radiator follows OE-level standards for core dimensions, tank design, fin pitch, and material selection.

For shoppers searching for a Honda S2000 radiator, 221-9222, or a Denso radiator for 2006-2009 Honda S2000 models, this unit provides the specified inlet and outlet sizing and does not include a transmission oil cooler.

What It Helps Address

• Overheating caused by reduced radiator efficiency
• Coolant temperature instability during stop-and-go driving
• Leaks or corrosion in an aging radiator core or tank assembly
• Poor fitment from non-OE-style replacement radiators
• Cooling system service needs on a 2006-2009 Honda S2000

Installation Notes and Tips

Verify core dimensions, inlet and outlet diameters, and mounting layout against the original radiator before installation. Inspect hoses, clamps, and coolant condition during replacement, and flush the cooling system if contamination or debris is present. Confirm that the vehicle does not require a transmission oil cooler connection, since this radiator is supplied without one.

Quality Assurance

Denso states that its radiators are built to OE standards and undergo durability and function testing before release. That manufacturing approach supports reliable cooling performance and consistent fitment for Honda S2000 owners replacing the factory radiator.
