Detailed Description

OSC part number 2596 is a replacement radiator for Ford F-150 and Ford F-150 Heritage trucks that require the listed 1" core configuration and quickconnect fittings. The radiator measures 31 7/8 in. tall by 16 13/16 in. wide, with a 1 in. core thickness and a crossflow layout. It uses plastic tanks, a PA core material, and a plated transmission oil cooler to match the original cooling package where equipped. The design follows OE-style form and function, with fitted components torqued to factory specifications and premium-grade materials selected for durability.

This part cross-references APDI 8012596 and Spectra Premium CU2596 for the same application. If you are replacing a radiator on a 2003-2004 Ford F-150 or 2004 Ford F-150 Heritage, 2596 provides a direct-fit cooling solution for the specified truck configurations.

Common Problems This Radiator Addresses

• Coolant leaks from a cracked or aging radiator tank
• Reduced cooling performance from a restricted or damaged core
• Transmission heat buildup when the cooler circuit is worn or failing
• Fitment issues caused by an incorrect core size or connector style
• Overheating concerns on higher-mileage Ford F-150 trucks

Installation Notes and Tips

Verify the vehicle’s core size and quickconnect style before installation. This radiator is specified for 1" core applications, and the fitment notes should be matched to the truck’s body style and model year. Inspect hoses, clamps, and related cooling-system components before assembly so the replacement radiator can be installed cleanly and sealed correctly.

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 radiator is also individually pressure tested during production to help confirm leak resistance and consistent build quality.
