Detailed Description

Koyorad A2409 is a radiator replacement for 2001-2004 Nissan Frontier and 2002-2004 Nissan Xterra models. It is built with an aluminum core and plastic end tanks, matching the OE-style construction commonly used in factory cooling systems. The 2-row core layout and integrated transmission oil cooler make this radiator a practical choice for vehicles that route automatic transmission fluid through the radiator assembly. Koyorad A2409 is a direct-fit cooling component for Nissan Frontier and Nissan Xterra owners looking for a replacement radiator with the correct core size and hose connections.

Koyorad uses technical manufacturing experience to produce OE-equivalent radiators that align with factory replacement needs. This part cross-references Denso (e.g., 221-0508) for the same application.

What It Helps Address

• Leaking radiator tanks or seams
• Restricted coolant flow from an aging core
• Overheating caused by reduced heat dissipation
• Transmission fluid cooling concerns in automatic-equipped vehicles
• Cracked or deteriorated factory radiator components

Installation Notes and Tips

Verify hose diameter, core dimensions, and transmission cooler connections before installation. Flush the cooling system and inspect hoses, clamps, and the radiator cap during replacement. Confirm fitment for your specific 2001-2004 Nissan Frontier or 2002-2004 Nissan Xterra configuration before removing the original radiator. Part number A2409 should be matched to the vehicle’s cooling system layout and transmission setup.
