2013 Chevrolet Silverado 1500 Thermostats

Genuine GM thermostats for the 2013 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.

What sends people here

Slow warm-up, a low temperature gauge, or poor heater output. On a light duty pickup, box length and cab style drive more part number splits here than the engine does.

What sets these apart

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

Before you order

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.
