Built to OE Dimensions

OSC part number 2851 is engineered around factory-style fitment for the Pontiac G6 radiator application. Core dimensions measure 26 3/4 inches high by 14 1/2 inches wide by 7/8 inch thick, with 1 5/16 inch inlet and outlet diameters. The unit uses premium tubes, fins, headers, and tanks, and the transmission cooler is integrated into the radiator assembly for vehicles originally equipped with that design. This radiator is a practical choice for a Pontiac G6 radiator replacement when the original unit is leaking, restricted, or no longer cooling efficiently.

This part cross-references APDI 8012727 and Spectra Premium CU2727 for the same application.

Common Reasons for Replacement

  • Coolant leaks from the radiator tank, core, or seams
  • Overheating during idle, stop-and-go traffic, or highway driving
  • Transmission fluid temperature concerns tied to the built-in cooler
  • Restricted coolant flow from age, corrosion, or internal wear
  • Cooling system service on a high-mileage Pontiac G6

Installation Notes

Verify the radiator dimensions, inlet and outlet sizes, and transmission cooler layout before installation. Transfer any required fittings or hardware from the original setup only if needed for your vehicle configuration. Flush the cooling system, inspect hoses and clamps, and confirm proper coolant fill and bleed procedure after installation. This radiator is a direct-fit replacement for 2006-2009 Pontiac G6 applications listed above.

Quality Assurance

OSC tests the transmission and engine oil coolers before assembly, checks the radiator core prior to assembly, and tests the completed unit again after assembly. The design uses cadmium-plated tubes and factory-style gasket sealing to help reduce premature failure and leakage. Part number 2851 is built to meet original-equipment-style cooling requirements for the Pontiac G6.
