If you are searching for a Honda Accord radiator replacement, Denso 221-3247 provides a direct application match for 2008, 2009, 2010, 2011, and 2012 models.

This part cross-references Honda (e.g., 19010-R70-A51, 19010-R72-A01) for the same application.

What It Helps Address

• Coolant leaks from a cracked or corroded radiator
• Overheating caused by reduced heat exchange efficiency
• Transmission fluid temperature control when the cooler circuit is part of the system
• Fitment issues from an incorrect replacement radiator
• Restricted cooling performance from aging core materials

Installation Notes and Tips

Verify the existing radiator dimensions, hose connection sizes, and transmission cooler routing before installation. Flush the cooling system, inspect hoses and clamps, and confirm the radiator mounts and fan shroud alignment on the Honda Accord before final assembly. After installation, refill with the correct coolant mixture and bleed air from the system according to vehicle service procedures.

Quality Assurance
