Built for OE-Style Cooling Performance

This radiator is designed around original-equipment dimensions and cooling layout for the Mazda Miata radiator application. OSC uses premium-grade tubes, fins, headers, tanks, and related components, along with a die-cut gasket to help maintain a secure seal. The radiator includes a concentric transmission oil cooler and follows the OE cooler design where originally equipped. Part number 2268 is also cross-referenced to Spectra Premium CU2268 for the same application.

Common Cooling Issues It Can Address

• Leaking radiator tanks or seals
• Restricted coolant flow from an aging core
• Transmission heat buildup in vehicles with an integrated cooler
• Cooling performance loss from worn fins or internal deterioration
• Fitment problems caused by non-OE-style replacement parts

Installation Notes and Fitment Tips

Fits 1999-2005 Mazda Miata, N/A. Verify inlet and outlet hose sizing, cooler line routing, and mounting points before installation. This radiator is engineered as a drop-in replacement with the necessary fittings or hardware included in each unit. Part Number 2268 should be matched to the vehicle’s original radiator configuration, especially when replacing a unit with an integrated transmission oil cooler.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core before assembly, and tests the completed unit again after assembly. The design also incorporates enhancements aimed at addressing original failure points and improving durability in higher-mileage vehicles.
