The thermostat part for a Honda Odyssey typically costs between about $10 and $70, depending on whether you choose an aftermarket or OEM part and whether you buy a standalone thermostat or a kit with gasket or housing. Labor, if you have it installed by a shop, is extra.
Understanding the price means recognizing that the thermostat regulates engine temperature by controlling coolant flow. Replacing it is a common maintenance task to prevent overheating. Prices vary by generation, retailer, and whether you’re buying just the valve or a full housing kit. This article provides current price ranges and buying tips for Odyssey owners.
Price ranges for Honda Odyssey thermostats
Prices vary by part type and retailer. The ranges below reflect typical market pricing as of 2024-2026 and may differ by region.
- Aftermarket thermostat (standalone, non-OEM): typically $8-$25
- OEM thermostat (Honda-branded, standalone): typically $20-$60
- Thermostat kit (thermostat with gasket and seals): typically $30-$100
- Thermostat assembly with housing (less common): typically $40-$120
For most repairs, an aftermarket thermostat suffices; OEM parts ensure exact fit and original specifications but cost more. Always check the correct part number for your Odyssey's year and engine variant.
Where to buy and how to save
Buying channels and tips to save on a Honda Odyssey thermostat:
- Online retailers (Amazon, AutoZone online, Advance Auto Parts, RockAuto) often have the widest selection and competitive prices
- Local auto parts chains (AutoZone, O'Reilly, NAPA) with in-store pickup and warranties
- Honda dealership parts counters offer OEM parts; prices are higher but warranties and easy returns
- Avoid using used or remanufactured thermostats unless the seller provides a clear warranty
Compare total costs, including shipping and any core exchanges. If you’re unsure about compatibility, have your vehicle's VIN handy when shopping.
Model-year considerations and installation tips
Thermostat design and housing compatibility can vary by Odyssey generation. Always verify compatibility with the exact year and engine type (most Odysseys use a 3.5L V6). If you’re replacing it yourself, keep these in mind:
- 2005-2010 (second generation): thermostat location and gasket style may differ from later generations; coolant may need to be drained
- 2011-2017 (third generation): generally similar replacement steps; check torque specs and hose clamps in the service manual
- 2018-present (fourth generation): newer part numbers and sometimes different housings; ensure you get the correct kit if replacing with housing
Labor costs vary by shop and region, typically ranging from $100 to $300 depending on labor rates and whether coolant replacement is included.
Summary
In short, you’ll typically spend about $10-$60 for a Honda Odyssey thermostat part, with OEM parts tending to be more expensive than aftermarket equivalents. For DIY repairs, an aftermarket thermostat is usually sufficient; for guaranteed fit and warranty, choose OEM. If you’re hiring a mechanic, budget additional labor costs, which vary by location and service shop.
