2010 GMC Sierra 1500 Radiators

Genuine GM radiators for the 2010 GMC Sierra 1500, at wholesale prices. Radiator part numbers split on engine, transmission cooler and tow package, and the fittings differ between them. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019 with the CarbonPro bed option.

When to replace

Overheating in traffic, or coolant pooling at the front of the vehicle. On a light duty pickup, cab configuration, drivetrain and box length all split this group, so the badge on the tailgate is not enough to order from.

What you get ordering from us

• Factory sourced. These radiators are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical radiators numbers for you.
• Ships from Dallas. Radiators ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on radiators that did not fit.

Avoiding the wrong part

Aftermarket versions are often close enough to install and far enough off to cause a repeat repair. Option packages divide this catalog more than model years do. Send the VIN and skip the problem. Our Dallas location means most of the country is inside a two or three day ground window.
