Detailed Description

This One Stop Solutions radiator is built to replace the original cooling unit in select Toyota 4Runner models while maintaining factory-style fit and function. The radiator uses premium materials, cadmium-plated tubes, and a die-cut gasket to help reduce leak risk and support long-term durability. The integrated concentric transmission cooler is designed for the original cooling layout where equipped, and the assembly is tested before and after core installation to verify performance.

Part number 1430 is a practical choice for a Toyota 4Runner radiator replacement when the original unit is leaking, restricted, or no longer cooling efficiently. This part cross-references CSF 2055 and Spectra Premium CU1430 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by reduced core efficiency
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Cooling performance loss in higher-mileage Toyota 4Runner vehicles
• Fitment issues from a damaged or previously repaired radiator assembly

Installation Notes and Tips

Verify core dimensions, inlet and outlet size, and transmission cooler layout before installation. This radiator is a downflow design, so confirm the vehicle’s original configuration matches the listed fitment. Inspect hoses, clamps, and mounting points during replacement to help prevent repeat leaks and ensure proper system sealing.

Quality Assurance

OSC-style engineering focuses on OE performance, factory-spec component placement, and multi-stage testing. Each radiator is pressure tested during production, and the transmission and engine oil cooler circuits are checked before final assembly and again after assembly to confirm integrity.
