2010 Buick LaCrosse Thermostats

Genuine GM thermostats for the 2010 Buick LaCrosse, at wholesale prices. The opening temperature is matched to the engine calibration, so an off-spec thermostat sets codes without failing outright. Epsilon II from 2010 to 2016 and a lighter redesign from 2017 to 2019.

What sends people here

Slow warm-up, a low temperature gauge, or poor heater output. On a full-size car, turbocharged and naturally aspirated cars share a badge and little else in this group.

What sets these apart

• 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.
• OEM, not lookalike. With thermostats the difference shows up on installation day, not in the photo.

Before you order

Genuine GM parts carry the factory part number, so supersessions are documented rather than guessed at. Run your VIN first. One vehicle can list several nearly identical parts and only one is correct. Because we ship centrally, a heavy part costs less delivered here than from a coastal seller.
