Detailed Description

OSC part number 2723 is a direct-fit radiator engineered for OE-style fit, form, and function in the Mitsubishi Galant. The radiator uses premium-grade aluminum construction with plastic tanks, cadmium-plated tubes, and a die-cut gasket to help reduce leak risk. It also includes a concentric transmission oil cooler and is built with factory-style component placement for a clean installation and proper cooling system alignment. This radiator cross-references Spectra Premium CU2723 for the same application.

Common Cooling Issues It Can Address

• Overheating caused by a restricted or aging radiator core
• Transmission fluid temperature concerns related to a worn cooler circuit
• Coolant leaks from deteriorated tanks, gaskets, or tube assemblies
• Reduced heat transfer from clogged or damaged internal passages
• Fitment problems from a radiator that no longer matches factory dimensions

Installation Notes and Tips

Verify vehicle configuration before ordering, since this radiator is listed for 2004-2012 Mitsubishi Galant models with a 2004-2009 overlap and a separate note for wo/CALIF EMISSIONS on the broader application. Confirm inlet and outlet sizes, cooler line routing, and mounting points against the original unit before installation. Flush the cooling system, inspect hoses and clamps, and check for proper fan operation after replacement.

Quality Assurance

OSC tests the radiator core before assembly, then tests the transmission and engine oil cooler circuits prior to installation into the tank, and tests the completed unit again after assembly. The design also incorporates engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
