Detailed Description

OSC designs this radiator to match original equipment form, fit, and cooling function for the Infiniti Q50. The core measures 14 15/16 inches high by 28 3/16 inches wide, with a 1-inch core thickness, 1 3/8-inch inlet and outlet diameters, and a concentric transmission oil cooler integrated into the assembly. Premium tubes, fins, headers, and tanks are used to improve durability, while cadmium-plated tubes help resist premature failure. Part number 13403 is engineered for multi-fit applications without changing the appearance or mounting profile of the original radiator.

This part cross-references 214604GB5A for the same application.

Common Cooling System Issues Addressed

• Overheating caused by a leaking or restricted radiator
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Coolant loss from cracked tanks or weakened seals
• Reduced heat transfer from aged core fins and tubes
• Fitment problems after replacing a damaged factory radiator

Installation Notes and Tips

Verify inlet and outlet sizing, header dimensions, and cooler connection layout before installation. This radiator is a direct-fit replacement for the 2014-2017 Infiniti Q50, and all necessary fittings or hardware are included in each unit. Transfer any reusable components from the original system as required by the vehicle configuration, and confirm proper hose routing and cooler line alignment during installation.

Quality Assurance

Each OSC radiator is pressure tested during production, including testing of the transmission and engine oil cooler circuits before tank installation, followed by core testing and a final assembled-unit test. The design incorporates factory-style components and engineering updates aimed at improving cooling performance and service life in higher-mileage vehicles. Part number 13403 is built to meet original equipment cooler design requirements where originally equipped.
