2010 Chevrolet Silverado 2500 HD Thermostats

Genuine GM thermostats for the 2010 Chevrolet Silverado 2500 HD, at wholesale prices. The opening temperature is matched to the engine calibration, so an off-spec thermostat sets codes without failing outright. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

Signs it is time

Slow warm-up, a low temperature gauge, or poor heater output. 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 thermostats number against your vehicle before it ships.
• Same day dispatch. Order thermostats by mid-afternoon and it leaves our warehouse that day.
• Returns without a fight. We would rather fix a thermostats order than argue about it.
• Covered by GM. On thermostats that coverage is worth more than the price gap.
• Real wholesale. The same thermostats your dealer sells, at a fraction over our cost.

Making sure it fits

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 Give us the number stamped on the old part and we will trace what it superseded to.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.
