Genuine GM radiators for the 2014 GMC Sierra 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.

Symptoms to look for

Overheating in traffic, or coolant pooling at the front of the vehicle. On a heavy duty pickup, trim, tow package and drivetrain each move part numbers within one model year.

Why order factory

• VIN verified fitment. We confirm the radiators number against your vehicle before it ships.
• Same day dispatch. Order radiators by mid-afternoon and it leaves our warehouse that day.
• Returns without a fight. We would rather fix a radiators order than argue about it.
• Covered by GM. On radiators that coverage is worth more than the price gap.
• Real wholesale. The same radiators your dealer sells, at a fraction over our cost.

Ordering correctly

The factory number ties back to GM engineering records, which is something no aftermarket catalog can offer. Give us the number stamped on the old part and we will trace what it superseded to. Same day shipping on in stock items, direct from one of the largest GM parts warehouses in the country.
