Detailed Product Overview

This radiator is built to match original equipment cooling layout and installation requirements for the Toyota Paseo and Toyota Tercel. The core uses premium aluminum components, while the tubes are cadmium plated to help resist premature failure. OSC also uses fitted components torqued to factory specifications and applies engineering updates that address common failure points in higher-mileage vehicles. Part number 1381 is a practical OE-style replacement for drivers needing a radiator that installs cleanly and maintains the factory look and fit.

This part cross-references APDI 8011381 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a worn or damaged radiator
• Overheating caused by reduced heat transfer
• Corrosion-related tube or tank deterioration
• Poor fitment from an aging original radiator
• Cooling system performance loss in higher-mileage Toyota Paseo or Toyota Tercel models

Installation Notes and Tips

Verify the vehicle’s radiator configuration before installation, including the 5/8 in. core specification and the absence of integrated oil coolers. Inspect hoses, clamps, and mounting points during replacement to help ensure a proper seal and stable fit. Because this unit is supplied without a cap, reuse or replace the cap separately as needed based on the vehicle’s cooling system requirements.

Quality Assurance

OSC tests complete radiators up to three times during production: cooler components are checked before tank installation, the core is tested before assembly, and the finished unit is tested again after assembly. This process supports leak resistance and consistent performance for the listed Toyota applications. Part number 1381 is engineered to meet OE-style cooler design requirements where originally equipped.
