Detailed Description

This radiator is engineered for OE replacement service on the Toyota Celica and follows original cooler design requirements where equipped. OSC uses premium tubes, fins, headers, and tanks, with cadmium-plated tubes inside and out to help reduce premature failure. The radiator is built with a 28 3/16 in. inlet and outlet header length, 1 15/16 in. header width, a 1 3/16 in. inlet diameter, and a 1 7/16 in. outlet diameter for a direct-fit installation profile. Part Number 1174 is also cross-referenced to Spectra Premium CU1174 for the same application.

Common Issues This Radiator Can Address

• Coolant leaks from an aging or damaged radiator core or tank
• Overheating caused by restricted cooling capacity
• Transmission fluid temperature concerns tied to a failing integrated cooler
• Corrosion-related radiator deterioration in higher-mileage vehicles
• Poor fitment from non-OE-style replacement radiators

Installation Notes and Tips

Verify the radiator dimensions, inlet and outlet sizes, and cooler layout against the original unit before installation. Transfer any required mounting components from the original assembly if applicable, and inspect hoses, clamps, and related cooling-system parts for wear before reassembly. This radiator is a direct replacement for 1990-1993 Toyota Celica applications with the listed configuration.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the core before assembly, and tests the completed radiator again after assembly. The design also incorporates engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles.
