Generally, you’ll pay about $10 to $60 for the thermostat part itself, with total installed costs typically in the $100 to $200 range depending on labor rates and whether a gasket is included. Expect aftermarket parts to be cheaper than OEM/GM options.
The thermostat is a small valve in the engine’s cooling system that controls when coolant flows to the radiator. Replacing it can require draining a portion of the coolant and removing part of the thermostat housing. For a 2006 Equinox, prices vary by engine variant (the vehicle offered both a 3.4L V6 and later a 3.6L V6) and by whether you choose aftermarket or OEM parts. Shopping around can yield meaningful savings, especially if you can bundle the gasket or housing with the thermostat.
Part price ranges for the thermostat
Below are typical price ranges you’ll encounter when shopping for the thermostat itself and related options for the 2006 Equinox.
- Aftermarket non-OEM thermostat (basic unit): $8–$25
- OEM GM thermostat (genuine GM/Delphi equivalent): $25–$60
- Thermostat housing assembly including thermostat and gasket: $60–$120
Prices vary by retailer, region, and whether you buy the part standalone or as part of a kit. Some listings also include additional components like a coolant hose or sensor, which can affect the total.
Understanding what you’re buying helps: a standalone thermostat is usually the cheapest option, while a housing assembly or kit can simplify installation and reduce the chance of missing a gasket or related part.
Where to buy
Common retailers and online sources where you can find a thermostat for a 2006 Equinox include:

Shopping around across brick-and-mortar stores and online retailers can yield noticeable savings, especially if you catch sales or use coupons. Verify compatibility with your engine variant (3.4L versus 3.6L, if applicable) and check whether the gasket or housing is included in the price.
Labor and total project cost
Labor costs and time can vary by shop and location. Replacing the thermostat on a 2006 Equinox is typically a relatively quick job, often around 0.5 to 1 hour for a competent mechanic, depending on accessibility and whether the housing needs to be replaced. Including labor, you can expect a ballpark total of about $100 to $200, with higher-end shops or additional work (like coolant replacement) pushing the total higher.
Engine options and compatibility
The 2006 Chevy Equinox offered a 3.4-liter V6 and, in some configurations, a 3.6-liter V6 over its model years. While the thermostat itself is a standard cooling component, some engine variants require a specific design or housing. Always confirm part compatibility with your exact engine code and VIN before ordering.
Summary
For a 2006 Chevy Equinox, plan for about $10–$60 for the thermostat part, and roughly $100–$200 total installed, depending on labor rates, whether you need a gasket or housing, and the exact engine variant. Shop around at auto parts stores and online retailers, compare OEM versus aftermarket options, and verify compatibility to ensure a smooth replacement.
