Detailed Description

This OSC radiator is built to match original equipment form and function for Ford E-Series vans and wagons that use 1/2" TOC fittings. The radiator measures 23 5/8 inches in core height, 29 5/16 inches in core width, and 1-7/16 inches in core thickness, with a 2-row crossflow configuration for efficient heat transfer. The unit uses premium-grade aluminum construction with plastic tanks and includes a plated transmission oil cooler, while the engine oil cooler is not included.

Part Number 2977 is engineered for a direct drop-in style installation and is assembled with fitted components torqued to factory specifications. OSC also uses enhanced core and fin design details to address common cooling-system wear in higher-mileage vehicles. This makes Part Number 2977 a practical replacement radiator for Ford E-150, Ford E-250, and Ford E-350 Super Duty cooling system service.

This part cross-references Spectra Premium CU2977 and Koyorad A2977 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a worn or damaged radiator tank or core
• Reduced cooling performance from age-related internal restriction
• Transmission heat management concerns in equipped applications
• Cracked or weakened plastic tank assemblies
• Cooling-system service needs on high-mileage Ford E-Series vehicles

Installation Notes and Tips

Verify the vehicle uses 1/2" transmission oil cooler fittings before installation. Confirm radiator dimensions, hose connections, and cooler line routing against the original unit to ensure proper fit. Because the cap is not included, reuse or replace the radiator cap as needed based on the vehicle’s cooling-system specification.

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. Each radiator is individually pressure tested to verify sealing and cooling-system integrity.
