Detailed Description

Denso Part Number 221-9104 is a radiator assembly developed with OE supplier experience and factory-level fitment in mind. Denso designs radiator tanks, fin pitch, core dimensions, and materials to meet original manufacturer standards, helping maintain proper engine cooling and consistent thermal performance. This makes the 221-9104 a practical replacement for drivers servicing a Ford Fusion radiator, Mercury Milan radiator, or Lincoln Zephyr radiator application.

What It Helps Address

• Engine overheating caused by a worn or restricted radiator
• Coolant leaks from aging radiator tanks or core damage
• Reduced cooling efficiency from clogged or corroded internal passages
• Transmission heat management concerns when the cooler circuit is part of the system
• Fitment issues from non-OE replacement dimensions

Installation Notes and Tips

Verify inlet and outlet sizing, core dimensions, and transmission cooler connections before installation. Flush the cooling system, inspect hoses and clamps, and replace degraded coolant components as needed. After installation, bleed air from the system and confirm there are no leaks or temperature irregularities during warm-up.
