Detailed Product Overview

This radiator uses a 34-inch core height, 17 1/4-inch core width, and 1-inch core thickness, with 1 5/16-inch inlet and 1 9/16-inch outlet diameters. The engine oil cooler is plated, and the cooler fittings are spaced 11 1/2 inches apart. For Chevrolet Silverado 3500 and related Chevrolet and GMC C/K truck applications, Part Number 2315 is built to match the original cooling layout while adding durability-focused enhancements.

This part cross-references Spectra Premium CU2315 and APDI 8011522 for the same application.

Common Problems This Radiator Addresses

  • Overheating caused by a worn or restricted radiator core
  • Coolant leaks from aging tanks, seams, or gasket surfaces
  • Reduced cooling efficiency in high-mileage Chevrolet and GMC trucks
  • Oil temperature management issues where an engine oil cooler is required
  • Fitment problems from damaged or mismatched replacement radiators

Installation Notes and Tips

Verify the vehicle’s original cooling configuration before installation, especially the presence of an engine oil cooler and the 1-1/4-inch core application noted in fitment. This radiator does not include a cap, and it does not include a transmission oil cooler. Confirm inlet and outlet hose sizes, cooler line routing, and mounting points before final assembly.

Part Number 2315 is designed for straightforward replacement in the listed Chevrolet Silverado 3500, Chevrolet C/K, and GMC C/K applications.

Quality Assurance

OSC radiators are produced with OES-style design targets and are individually pressure tested during manufacturing. The radiator core, engine oil cooler, and assembled unit are tested at multiple stages to help verify sealing and performance before shipment.
