2011 GMC Sierra 1500 Water Pumps

Genuine GM water pumps for the 2011 GMC Sierra 1500, at wholesale prices. Factory pumps hold the original impeller design and flow rate the cooling system was calibrated around. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019 with the CarbonPro bed option.

Signs it is time

Coolant seepage at the weep hole or a whine that tracks engine speed. On a light duty pickup, box length and cab style drive more part number splits here than the engine does.

What sets these apart

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