2012 GMC Sierra 2500 HD Radiator and Coolant Hoses

Genuine GM radiator and coolant hoses for the 2012 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 to replace

Swelling, soft spots, or seepage at the clamp. 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.

Buying OEM, briefly

• GM stands behind it. The radiator and coolant hoses warranty comes from the manufacturer, not from us.
• Priced below the dealer. Radiator and Coolant Hoses at up to 40 percent off list, with no membership.
• Factory sourced. These radiator and coolant hoses are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical radiator and coolant hoses numbers for you.
• Ships from Dallas. Radiator and Coolant Hoses ordered by 3pm Central go out the same business day.

Avoiding the wrong part

Original tooling means original fit, which matters most on anything that has to align with a neighboring part. Our VIN lookup is more accurate than any public catalog. Use it before you check out. In stock orders placed by 3pm Central ship the same business day from our Dallas warehouse.
