The thermostat part for a 2010 Honda Civic typically costs about $15 to $120, depending on whether you choose an aftermarket or OEM unit and whether you buy just the valve or a housing-inclusive assembly; labor, if you have a shop install it, is extra.
Prices vary by engine variant (most Civics use a 1.8-liter engine, while some trims or markets may differ) and by retailer. This guide breaks down typical price ranges, where to buy, and what to expect for installation and compatibility.
Prices by type and source
Prices for the thermostat can differ depending on whether you opt for an original-equipment part, an aftermarket alternative, and whether the part is sold as a standalone valve or as part of the housing. Here are representative ranges commonly seen in North American markets.
- Aftermarket thermostat (valve only): typically $10–$30.
- OEM thermostat (valve only, Honda-branded): commonly $30–70.
- OEM thermostat with housing: usually $60–120.
- Aftermarket thermostat with housing or complete thermostat assembly: typically $40–80.
- Used or salvage-yard thermostat (parts-only): often $5–25.
Prices can vary by retailer, region, and whether you purchase online or in a store, and some retailers may charge shipping or handling that affects the total.
Where to buy and what to look for
To ensure compatibility with a 2010 Civic, confirm the engine type (the 1.8L is standard for most Civics of that year, with variations in certain trims) and verify the part number with the retailer. You can buy from a Honda dealership, auto parts stores, or online marketplaces. Here is a snapshot of common buying options and what to expect.
- Honda dealership: typically higher-end OEM pricing (often $60–120 for the housing-inclusive unit) but guaranteed fit and original specs.
- Major auto parts chains (AutoZone, O'Reilly, Advance): a wide range of aftermarket options, around $10–80 depending on brand and housing included.
- Online retailers and marketplaces: broad price range, often $10–60 for aftermarket parts, sometimes lower for generic brands; check seller ratings and return policy.
- Salvage yards / used parts: the lowest cost, usually $5–25; verify functionality and inspect for corrosion.
Always verify compatibility by cross-referencing the part number with your vehicle’s VIN or engine code, and confirm whether the price includes the gasket or requires a purchase separately.
Labor and installation considerations
Replacing a thermostat is a straightforward job for a trained technician, typically taking about 1 to 2 hours depending on access and whether the thermostat housing must be removed. Labor rates vary by region and shop, with typical ranges.
- Labor time: about 1–2 hours in most Civics.
- Shop labor rate: roughly $80–150 per hour in many regions; urban areas can be higher.
- Potential extra costs: replacement coolant, gasket/seal, or other cooling-system components discovered during replacement.
Budget for additional coolant and any required hose or gasket replacements when planning the service.
How to ensure you’re buying the right part
Because there are multiple engine variants for the Civic and different thermostat assemblies, double-check compatibility before purchasing. The best practice is to:
Engine variants and part numbers
- Know your engine code (for most 2010 Civics this is 1.8L, but check your VIN).
- Compare part numbers between your old part and the new one; if you can, bring the old thermostat to the store for matching.
- Ask about included gaskets; if not included, plan to buy a gasket kit.
Gaskets and seals
- Confirm whether the gasket is included with the new thermostat or if it must be purchased separately.
- Inspect the cooling-system hoses and seals for wear during replacement and replace as needed to prevent leaks.
Running through these checks helps avoid ordering the wrong part and saves time if an exchange is needed.
Summary
The price of a thermostat for a 2010 Honda Civic varies broadly depending on whether you choose an OEM or aftermarket part and whether you buy the thermostat alone or with the housing. Expect roughly $10–30 for aftermarket valve-only units, $30–70 for OEM valve-only units, and $60–120 for OEM housing-inclusive units, with labor typically adding about $100–$200 at a shop. Always verify compatibility with your engine code or VIN and consider your option between new, aftermarket, or used parts. If you’re not comfortable with DIY replacement, a professional installation ensures the cooling system remains leak-free and properly calibrated.
Summary of key takeaways: price ranges vary by part type and source; verify compatibility before purchase; factor in labor if you’re not doing it yourself; and consider whether you want OEM reliability or a more economical aftermarket option.
