The typical total is about $200 to $350 at a shop, including parts and labor. In high-cost areas or at a GM dealership, prices can be higher, while DIY parts costs will be lower if you have the tools and skills.
Replacing the thermostat on a 2015 Chevy Equinox involves draining and refilling coolant, removing the thermostat and any surrounding housing, installing the new unit, and testing the cooling system. The job can vary based on engine type (2.4L inline-4 or 3.6L V6), whether the thermostat comes as a separate part or with the housing, and whether coolant replacement or additional cooling-system work is needed.
What affects the cost
Several factors can influence the final bill beyond the basic parts and labor:
- Engine variant (2.4L I4 vs 3.6L V6) and whether the thermostat is a standalone unit or part of a housing.
- Whether coolant replacement or a coolant flush is performed, which adds material and labor time.
- Regional labor rates and shop diagnostic fees.
- Whether additional cooling-system components (such as the water pump, radiator hoses, or radiator) are found to need replacement.
In practice, most customers see costs in the mid-range unless additional repairs are required or you’re in a high-cost market.
Typical price range
Prices can vary by region and by whether you go through a dealership or an independent shop. The following ranges reflect common costs for a thermostat replacement on a 2015 Equinox.
- Parts: $20–$80 for the thermostat kit; $60–$150 if the housing is included or if OEM parts are specified.
- Labor: $100–$230, typically 1–2.5 hours at common shop rates, depending on engine layout and accessibility.
- Coolant: $5–$15 for an extra quart or two if a drain/refill is performed.
- Other fees (diagnostic, shop supplies, disposal): $0–$60 depending on the shop.
Overall, independent shops commonly charge roughly $180 to $320 for a standard thermostat replacement. In higher-cost areas or at a dealership, total costs can run upward toward $350–$500.
DIY considerations
If you’re considering a do-it-yourself replacement, you’ll primarily save on labor costs, though you’ll still pay for parts and coolant. Bearings in mind the car’s coolant system is pressurized and improper reassembly can cause leaks or overheating.
- Pros: Potentially lower total cost, hands-on control, no dealer diagnostic fees.
- Cons: Requires mechanical skill, proper tools, and knowledge of coolant reuse/replacement; risk of leaks or air pockets if not done correctly.
For DIY projects, plan for parts in the $20–$80 range and be prepared to buy or borrow tools, plus a small amount of coolant. Expect significant time if you’re not experienced, and consult a repair manual for your engine variant.
Where to get an estimate
Getting multiple quotes helps ensure you’re paying a fair price for a thermostat replacement. Consider the following sources:
- GM dealership service department
- Independent auto repair shops
- National chains and fast-lix shops (if available in your area)
- Online price quotes or parts-and-l Labor estimators
- Mobile mechanics who can perform the service on-site
Always request a written estimate that breaks down parts, labor, coolant, and any shop fees before authorizing work. This helps prevent surprises and clarifies what you’re paying for.
Summary
Replacing a thermostat on a 2015 Chevy Equinox typically costs around $180 to $320 at an independent shop, with higher figures possible at dealerships or in high-cost regions. The price hinges on engine type, whether the thermostat is sold separately or with the housing, coolant needs, and local labor rates. Getting multiple quotes and asking for itemized breakdowns will help you secure a fair deal. If you’re comfortable with car maintenance, a DIY replacement can reduce costs further, but weigh the risks and required tools carefully.
