Built for OE-Style Cooling Performance

Part number 1721 is engineered to match original equipment form and function while adding durability-focused improvements. OSC uses cadmium-plated tubes inside and out to help resist premature failure, along with a die-cut gasket for leak resistance. The radiator is designed with fitted and torqued components to factory specifications and includes the necessary fittings or hardware for installation. This part cross-references APDI 8011721 for the same application.

Common Cooling Issues This Radiator Addresses

• Leaking radiator tanks or seams
• Reduced cooling efficiency from an aging core
• Transmission fluid temperature concerns tied to a worn cooler circuit
• Corrosion-related radiator failure in high-mileage vehicles
• Fitment problems caused by non-OE-style replacement parts

Installation Notes and Tips

Verify inlet and outlet sizing, header dimensions, and cooler line spacing before installation. Part number 1721 is a direct replacement radiator for 1995-1997 Ford Ranger and 1995-1997 Mazda B4000 applications, so it should be matched to the vehicle’s original cooling configuration before removal of the old unit. Flush the cooling system, inspect hoses and clamps, and confirm proper transmission cooler line routing during installation.

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 such as increased fin density and a thicker core to address heat load in higher-mileage vehicles. Part number 1721 is built to OE cooler design standards where originally equipped.
