2010 Chevrolet Impala Thermostats

Genuine GM thermostats for the 2010 Chevrolet Impala, at wholesale prices. The opening temperature is matched to the engine calibration, so an off-spec thermostat sets codes without failing outright. W-body through 2013 and the Epsilon II from 2014 to 2020.

What sends people here

Slow warm-up, a low temperature gauge, or poor heater output. On a full-size car, trim and package content split these part numbers in ways a diagram will not show.

Why buy OEM here

• Wholesale pricing. Most thermostats numbers land well below dealer list.
• No aftermarket substitutes. These are GM thermostats, not OE-style equivalents.
• We catch the wrong part before you do. VIN verification is free on every thermostats order.

Before you order

OEM components carry GM warranty coverage, which is usually worth more than the price gap on the invoice. If you are unsure which version you have, give us the VIN and our specialists will confirm fitment. Stock moves out the door the day you order it, assuming you beat the mid-afternoon cutoff.
