Detailed Description

This OSC radiator is designed for Mazda 3 cooling system service where OE-style fitment and factory-style routing matter. The radiator uses premium-grade aluminum components, cadmium-plated tubes, and a die-cut gasket to help maintain a secure seal. It is built as a crossflow unit with matching inlet and outlet header dimensions, and it is engineered for multi-fit applications without changing the look or fit of the original layout. Part number 2696 also cross-references Spectra Premium CU2696 for the same application.

For Mazda 3 owners searching for a radiator replacement by year and model, this unit supports 2004, 2005, 2006, 2007, 2008, and 2009 Mazda 3 applications. The design includes factory-spec component fitment and is assembled with enhancements aimed at improving cooling performance and service life in higher-mileage vehicles.

Common Problems This Part Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or inefficient heat exchange
• Corrosion-related radiator failure in the cooling core or tubes
• Fitment issues from a damaged or previously repaired radiator
• Reduced cooling performance in a high-mileage Mazda 3

Installation Notes and Tips

Verify inlet and outlet hose sizes, mounting points, and overall dimensions before installation. This radiator is a direct replacement for the listed Mazda 3 applications, but the cooling system should be inspected for worn hoses, clamps, and contaminated coolant before the new unit is installed. Flush the system if debris, rust, or old coolant is present, and confirm proper bleed procedure after installation to help prevent air pockets.

Quality Assurance

OSC tests the radiator core before assembly and tests the completed unit again after assembly. The transmission and engine oil cooler circuits are also tested before installation into the tank when equipped. This part is built to OE-style performance standards with premium materials and factory-spec component placement for consistent service on the Mazda 3 platform.
