2010 GMC Sierra 2500 Radiators

Genuine GM radiators for the 2010 GMC Sierra 2500, at wholesale prices. Radiator part numbers split on engine, transmission cooler and tow package, and the fittings differ between them. Catalog listing covering the light duty 2500 through 2004 and continuing as an alias for the 2500 HD.

When to replace

Overheating in traffic, or coolant pooling at the front of the vehicle. On a heavy duty pickup, box length and cab style drive more part number splits here than the engine does.

Buying OEM, briefly

• GM stands behind it. The radiators warranty comes from the manufacturer, not from us.
• Priced below the dealer. Radiators at up to 40 percent off list, with no membership.
• 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.

Avoiding the wrong part

Original tooling means original fit, which matters most on anything that has to align with a neighboring part. Our VIN lookup is more accurate than any public catalog. Use it before you check out. In stock orders placed by 3pm Central ship the same business day from our Dallas warehouse.
