2010 Chevrolet Avalanche Thermostats

Genuine GM thermostats for the 2010 Chevrolet Avalanche, at wholesale prices. The opening temperature is matched to the engine calibration, so an off-spec thermostat sets codes without failing outright. GMT800 for 2002-2006 and GMT900 for 2007-2013, with the midgate that folds the bulkhead into the bed.

Symptoms to look for

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.

Why order factory

• We catch the wrong part before you do. VIN verification is free on every thermostats order.
• Fast out the door. In stock thermostats ship within hours, not days, from Dallas.
• 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.

Ordering correctly

Materials and coatings are specified, not approximated, which is why factory parts last through more heat cycles. Check the VIN before ordering anything that has to bolt to something else. Shipping is calculated on real weight and distance, which usually beats a padded flat rate.
