2012 GMC Sierra 1500 Radiators

Genuine GM radiators for the 2012 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.

Signs it is time

Overheating in traffic, or coolant pooling at the front of the vehicle. On a light duty pickup, two trucks with the same badge can take different parts once cab style and drivetrain are accounted for.

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.

Making sure it fits

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.
