2012 Chevrolet Silverado 1500 Thermostats

Genuine GM thermostats for the 2012 Chevrolet Silverado 1500, at wholesale prices. The opening temperature is matched to the engine calibration, so an off-spec thermostat sets codes without failing outright. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019.

Symptoms to look for

Slow warm-up, a low temperature gauge, or poor heater output. On a light duty pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.

Why buy OEM here

• Real wholesale. The same thermostats your dealer sells, at a fraction over our cost.
• OEM, not lookalike. With thermostats the difference shows up on installation day, not in the photo.
• VIN verified fitment. We confirm the thermostats number against your vehicle before it ships.

Ordering correctly

Buying factory removes the variable. You are installing what the plant installed. We would rather spend two minutes verifying than process a return next week. Orders confirmed before mid-afternoon Central are on a truck that evening.
