• Crossflow radiator design with 2-row core
• Transmission oil cooler included; engine oil cooler not included
• Cadmium-plated tubes inside and out to resist premature failure
• Die-cut gasket design for leak resistance
• Individually pressure tested during production
• Factory-style fit, form, and function for direct replacement use
• Part number 2510 is engineered for multi-fit applications without changing the OE appearance

Detailed Description

This radiator is built around the original equipment layout for heavy-duty Chevrolet and GMC trucks, including Silverado 2500 HD, Silverado 3500, Sierra 2500 HD, and Sierra 3500 models from 2001 through 2005. The core measures 34 1/8 inches high by 19 7/16 inches wide, with a 2-3/16 inch thickness, and uses a crossflow configuration with 1 13/16 inch inlet and outlet diameters. OSC uses premium-grade tubes, fins, headers, tanks, and related components to improve durability and cooling performance while maintaining OE-style fitment. Part number 2510 also includes a plated transmission cooler and is assembled to factory specifications for a clean installation and consistent sealing.

This part cross-references Anchor 2919 and Spectra Premium CU2510 for the same application.

What It Helps Solve

• Overheating caused by a worn or restricted radiator core
• Transmission fluid temperature issues related to a failing cooler circuit
• Coolant leaks from aged tanks, seams, or gasket surfaces
• Reduced cooling efficiency in high-mileage Silverado and Sierra HD trucks
• Fitment problems from non-OE-style replacement radiators

Installation Notes and Tips

Compatible With 2001-2005 Chevrolet Silverado 2500 HD, 2001-2005 Chevrolet Silverado 3500, 2001-2005 GMC Sierra 2500 HD, and 2001-2005 GMC Sierra 3500. Verify core dimensions, inlet and outlet size, and transmission cooler connection spacing before installation. This radiator does not include a cap, and it does not include an engine oil cooler. Use the factory mounting points and confirm all hose and cooler line connections are clean before final assembly.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core prior to assembly, and tests the completed unit again after assembly. The design also incorporates engineering updates aimed at addressing common original design failure points in higher-mileage vehicles.
