2013 GMC Sierra 2500 HD Radiators

Genuine GM radiators for the 2013 GMC Sierra 2500 HD, at wholesale prices. Radiator part numbers split on engine, transmission cooler and tow package, and the fittings differ between them. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

Symptoms to look for

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.

The case for genuine GM

• 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.
• GM stands behind it. The radiators warranty comes from the manufacturer, not from us.

Ordering correctly

When a component is superseded, GM documents why. That history is worth having when something failed early. Two vehicles off the same line in the same week can take different parts. The VIN is how we tell. Most orders leave the same day. Oversized and freight items take an extra day to crate.
