Detailed Description

One Stop Solutions part number 13007 is a premium replacement radiator engineered to match OE cooling system layout and fit. It uses premium-grade aluminum construction details in the cooling assembly, with cadmium-plated tubes inside and out to help resist premature failure, plus fitted components torqued to factory specifications. The radiator is built with a plated transmission oil cooler and no engine oil cooler, making it a direct solution for vehicles originally equipped with heavy duty cooling. This part cross-references Spectra Premium CU13007 and Four Seasons 56505 for the same application.

Fits 2008-2017 Buick Enclave, N/A, w/HEAVY DUTY COOLING. Fits 2009-2017 Chevrolet Traverse, N/A, w/HEAVY DUTY COOLING. Fits 2017 GMC Acadia Limited, N/A, w/HEAVY DUTY COOLING. Fits 2007-2016 GMC Acadia, N/A, w/HEAVY DUTY COOLING. Fits 2007-2010 Saturn Outlook, N/A, w/HEAVY DUTY COOLING.

Common Cooling System Issues It Can Address

• Overheating caused by a failing or restricted radiator
• Transmission fluid temperature concerns tied to a worn cooler circuit
• Coolant leaks from aging tanks, seams, or gasket surfaces
• Reduced cooling efficiency in high-mileage heavy duty cooling vehicles
• Temperature instability during stop-and-go or towing use

Installation Notes and Tips

Verify the vehicle is equipped with heavy duty cooling before ordering. Confirm inlet and outlet sizes, core dimensions, and cooler line routing against the original radiator. The 13007 is built for drop-in style replacement on the listed applications, and all necessary fittings or hardware are included with the unit. After installation, refill with the correct coolant, bleed the system, and inspect for leaks at the cooler connections and tank seams.

Quality Assurance

OSC radiators are produced with multiple inspection steps during manufacturing, including testing of the transmission and engine oil coolers before tank installation, core testing before assembly, and a final test after assembly. The design also incorporates enhancements aimed at addressing common OE failure points and improving service life in higher-mileage vehicles.
