For a 1999 Honda Accord, the thermostat part typically costs about $6 to $60, depending on aftermarket vs OEM and whether it includes a gasket or a housing. Installed by a shop, total costs commonly range from roughly $100 to $250.
What you’re buying when you shop for a thermostat
Prices vary by part type and brand. Here are typical ranges:
- Aftermarket thermostat only (non-OEM): typically $6–$20
- OEM/manufacturer-brand thermostat: usually $25–$60
- Thermostat with gasket or seal kit: around $5–$15 extra
- Thermostat with housing included: roughly $30–$90
Note: Some kits include sensors or extra seals; check product descriptions before purchase.
What affects the price
Several factors influence exact price:
- Brand and whether it is a genuine Honda part or aftermarket
- Engine variant (2.2/2.3L four-cylinder or other configurations) may affect compatibility
- Where you buy (local auto parts store vs online retailer vs dealership)
- Whether the thermostat is sold alone or as part of a housing or kit
Shop around and verify compatibility with your exact VIN and engine code.
Labor and installation costs
Installing a thermostat is a moderate job. Labor prices vary by region and shop, but typical ranges are:
- Labor: about $75–$150 per hour, with 1–2 hours common
- Total labor cost: roughly $75–$300 depending on location and complexity
- DIY savings: you can save on labor by replacing the part yourself, but ensure you have the right tools and cooling system precautions
Remember that some vehicles may require coolant flush or air bleeding, which can add to time and cost.
DIY considerations
If you choose to DIY, follow safe procedures: allow cooling system to drain, replace with new gasket, refill with correct coolant type, and purge air from the system. YouTube tutorials for the 1999 Accord can help, but a shop visit might be safer if you’re unsure.
Where to buy and tips for choosing
Where you buy can affect price and guarantees. Consider:
- Auto parts chains (AutoZone, Advance Auto Parts, O'Reilly) offer affordable aftermarket thermostats and weekend pickup
- Dealerships stock OEM parts with a higher price but guaranteed fit
- Online marketplaces (Amazon, RockAuto) often have wide selection and competitive pricing
- Look for warranty (usually 1–2 years) and return policy
Compare part numbers to ensure compatibility with your 1999 Honda Accord’s engine code and VIN.
Summary
For a 1999 Honda Accord, expect the thermostat part itself to cost roughly 6 to 60 dollars, with broader options including housing and gasket kits. Labor adds roughly 75 to 300 dollars at a shop. Shopping around for OEM vs aftermarket, and whether you handle the job yourself, can significantly affect total cost. Always ensure compatibility and proper coolant handling to avoid overheating and engine damage.
