Detailed Description

OSC part number 2585 is a replacement radiator for the 2003-2006 Kia Sorento that follows OE-style fit and function. The radiator uses a single-row core, aluminum construction, and plastic tanks, with a concentric transmission oil cooler built into the assembly. Core and header dimensions are engineered for direct replacement, and the unit is produced with factory-style component placement to support proper fit in the Sorento cooling system. This part cross-references Spectra Premium CU2585 for the same application.

What This Radiator Helps Address

• Overheating caused by a restricted or leaking radiator
• Transmission fluid temperature issues related to a failing cooler circuit
• Coolant loss from cracked tanks, worn seals, or damaged headers
• Reduced cooling performance from aged fins or internal tube wear
• Fitment problems after replacing a damaged original radiator

Installation Notes and Tips

Confirm inlet and outlet hose sizes, cooler line routing, and overall core dimensions before installation. Transfer any required vehicle-specific components from the original radiator if needed, and inspect hoses, clamps, and coolant condition at the same time. After installation, refill with the correct coolant, bleed air from the system, and verify there are no leaks at the radiator, hose connections, or transmission cooler fittings.

Quality Assurance

OSC radiators are produced with engineering updates aimed at improving cooling performance and service life, including enhanced fin density and reinforced cooling capacity where needed. Each unit is pressure tested during production, with cooler and core testing performed before and after assembly to verify sealing and function.
