Detailed Description

OSC designs this radiator to match original equipment form and function for Dodge Ram cooling system replacement. The unit uses premium-grade aluminum tubes and cadmium-plated tubes inside and out to help resist premature failure, while the die-cut gasket supports a leak-resistant seal. Each radiator is pressure tested during production, and the assembly is engineered for multi-fit without changing the look or fit of the original application. The radiator measures 24 1/8 inches in core height, 29 inches in core width, and 1-1/4 inches in core thickness, with 2-inch inlet and outlet connections.

What This Radiator Helps Address

• Overheating caused by a worn or restricted radiator core
• Coolant leaks from aging tanks, seals, or core joints
• Reduced cooling efficiency in high-mileage Dodge Ram trucks
• Heat buildup from a radiator that no longer maintains proper flow
• Fitment issues when replacing a damaged OE-style crossflow radiator

Installation Notes and Tips

Verify core dimensions, inlet and outlet size, and cooler configuration before installation. This radiator is a direct-fit replacement for select 2004-2006 Dodge Ram 1500 and 2003 Dodge Ram 2500 and 3500 applications. Confirm that your vehicle does not require an engine oil cooler or transmission oil cooler in the radiator assembly, since this unit is supplied without either cooler.

Quality Assurance

OSC tests the radiator core before assembly and tests the completed unit again after assembly. The manufacturer also pressure tests the transmission and engine oil cooler circuits before installation into the tank when those circuits are present on the design. This part is built to OES-style specifications for consistent fit, function, and cooling performance.
