Product Details

TYC Radiator 2303 is engineered around the listed Mazda Protege fitment and uses an aluminum core with a downflow flow configuration. The radiator includes a concentric transmission oil cooler, which supports vehicles equipped with automatic transmission cooling through the radiator assembly. Connection points use hose clamp inlet and outlet fittings with 1.10 in. inlet and outlet diameters. This part also cross-references Spectra Premium CU2303 for the same application.

TYC Radiator is the brand line for TYC cooling components, and this radiator follows that product family’s OE-style replacement approach for radiator service on the Mazda Protege. The part number 2303 is also noted to fit 2302 applications, and the same radiator is listed for 1999-2000 Mazda Protege coverage.

Common Problems This Radiator Addresses

  • Coolant leaks from a damaged or corroded radiator core
  • Overheating caused by restricted coolant flow
  • Transmission fluid temperature control issues when the cooler circuit is compromised
  • Cracked or weakened plastic-and-metal radiator assemblies
  • Reduced cooling performance from age-related wear

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and transmission cooler line connection style before installation. Flush the cooling system, inspect hoses and clamps, and confirm the fan, thermostat, and coolant condition are in good working order before placing the vehicle back in service. This radiator uses hose clamp connections and tube-fitting transmission cooler ports, so line routing should match the original setup on the Mazda Protege.

Quality Assurance

TYC cooling components are built as replacement parts for vehicle-specific applications, and this radiator is listed with detailed dimensional and connection specifications to support proper fitment on the Mazda Protege. Confirm the vehicle year and transmission configuration against the fitment data before ordering.
