Detailed Product Overview

Part Number 2409 is engineered to match original equipment form and function while addressing common cooling-system wear points. OSC uses premium-grade tubes, fins, headers, and tanks, along with factory-spec component fitment and torque control during assembly. The radiator is individually pressure tested and built for multi-fit applications without changing the intended appearance or fit.

For Nissan Frontier and Nissan Xterra owners searching for a direct-fit radiator replacement, this unit supports OE-style cooling performance and includes the transmission cooler configuration originally equipped on the vehicle. The core and tank layout are designed for straightforward replacement in 2001-2004 Frontier and 2002-2004 Xterra models.

This part cross-references Spectra Premium CU2409 and Koyorad A2409 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Reduced cooling performance from a restricted or damaged core
• Transmission fluid temperature concerns related to a failing cooler circuit
• Overheating caused by internal corrosion or tube failure
• Fitment issues after replacing a damaged factory radiator

Installation Notes and Tips

Verify inlet and outlet sizes, core dimensions, and transmission cooler routing before installation. Inspect hoses, clamps, and surrounding cooling components for wear, and flush the system if contamination is present. This radiator is designed for direct replacement service on the listed Nissan Frontier and Xterra applications.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core before assembly, and tests the completed unit again after assembly. The design also incorporates engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
