2012 Chevrolet Silverado 2500 HD Radiators

Genuine GM radiators for the 2012 Chevrolet Silverado 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.

How you know

Overheating in traffic, or coolant pooling at the front of the vehicle. On a heavy 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 sets these apart

• No hassle returns. If the radiators is not right, send it back.
• Warranty intact. OEM radiators keep coverage that an aftermarket part can void.
• Wholesale pricing. Most radiators numbers land well below dealer list.
• No aftermarket substitutes. These are GM radiators, not OE-style equivalents.

Confirming fitment

A part validated on this vehicle behaves differently from one validated across a range of vehicles. Fitment questions are the one thing worth a phone call before checkout rather than after delivery. We ship from Dallas, which keeps transit times short across most of the country.
