Owners typically pay between about $15 and $120 for the thermostat part itself, with total installed costs commonly in the $120 to $260 range depending on model year, OEM versus aftermarket parts, and local labor rates. This article breaks down the price ranges, what influences the cost, and where to buy.
What affects the price
Parts options and price ranges
Below is a quick breakdown of typical price ranges you’ll encounter when shopping for a Civic thermostat, from basic aftermarket parts to OEM kits.
- OEM Honda thermostat kit (gasket included): commonly $35–$80, depending on model year and whether the kit includes a housing.
- Aftermarket/non-OEM thermostat: typically $10–$40.
- Thermostat with housing included (case/cover and seals): usually $60–$120.
- Used or remanufactured thermostat: roughly $0–$40, which carries higher uncertainty and risk.
Prices vary by Civic generation and seller. Dealer parts tend to be higher, while aftermarket options can be significantly cheaper but may come with shorter warranties.
Labor and total installed cost
Before estimating the final bill, consider labor and any related services that impact total cost.
- Labor: typically 1–2 hours at regional shop rates of about $70–$120 per hour, depending on local labor costs and the shop’s policies.
- Coolant and incidental supplies: about $5–$30 for coolant plus any hoses or clamps that need replacement.
- Estimated total installed price: generally around $150–$260 for most Civics, with higher totals if you’re at a dealership or in a high-cost area.
Some shops may include a coolant flush or other minor services in the price, while others itemize these separately. Always ask for a written estimate before work begins.
Where to buy and how to choose
Shopping guidance helps you balance price, warranty, and fit for your specific Civic.
- OEM parts from Honda dealerships or certified parts distributors: higher price but strong fit and reliability, with robust warranty.
- Aftermarket parts from auto parts stores or reputable online retailers: lower price and good coverage, but check compatibility and warranties for your model year.
- Used or remanufactured units: lowest upfront cost but higher risk of intermittent reliability or shorter remaining life.
When choosing, verify compatibility with your Civic’s exact model year and engine code (some Civics use different thermostats across generations). Read warranty terms and consider whether you prefer dealership peace of mind or a cost-saving independent shop.
Summary
The thermostat alone is a relatively affordable part, but total cost hinges on labor and parts selection. Expect roughly $15–$120 for the part, with installed prices commonly $120–$260 depending on your Civic model, where you shop, and how much work your mechanic includes (coolant, hoses, or extra services). Compare OEM versus aftermarket options, and obtain a written estimate to avoid surprises. Regular maintenance and proper coolant handling during replacement help prevent future cooling-system issues.
