Detailed Description

OSC part number 2759 is a replacement radiator for the 2003, 2004, 2005, and 2006 Hyundai Santa Fe. It uses a 15 3/4-inch core height, 28 1/4-inch core width, and 1-inch core thickness, with 1 3/8-inch inlet and outlet diameters. The radiator includes a concentric transmission oil cooler and is built with premium aluminum core materials and plastic tanks for OE-style packaging and fit.

The design focuses on direct replacement service for the Hyundai Santa Fe cooling system, with engineering updates aimed at improving durability and heat management. OSC also tests the radiator core and cooler circuits during production to verify sealing and performance before the unit leaves the factory.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted coolant flow or reduced heat transfer
• Transmission fluid temperature concerns related to a failing cooler circuit
• Corrosion or internal wear in the original radiator assembly
• Fitment issues after replacing a damaged OE radiator

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and cooler line routing before installation. Transfer any required vehicle-specific connections from the original unit as needed, and inspect hoses, clamps, and coolant condition while the system is open. After installation, refill with the correct coolant mixture, bleed air from the system, and check for leaks at the radiator, cooler fittings, and hose connections.

Quality Assurance

OSC builds this radiator to OE-style specifications and pressure tests each unit during production. The radiator core is tested before assembly, the cooler circuits are tested prior to installation into the tank, and the completed assembly is tested again to confirm sealing and function.
