2011 GMC Sierra 2500 HD Radiator and Coolant Hoses

Genuine GM radiator and coolant hoses for the 2011 GMC Sierra 2500 HD, at wholesale prices. Molded hoses are shaped to clear the accessory drive and exhaust, which generic hose cannot do. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

When you need them

Swelling, soft spots, or seepage at the clamp. On a heavy duty pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.

What sets these apart

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

Getting the right part

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.
