In most Honda Odysseys, the timing belt tensioner part typically costs about $40 to $180, depending on whether you choose aftermarket or OEM, plus installation and related components. Labor and other parts can significantly affect the total bill.
What the price covers and how it varies
The following ranges reflect the price of the tensioner unit itself (parts only) and account for different brands and generations of the Odyssey. They do not include labor, belt, water pump, or other components that might be recommended during a timing belt service.
- OEM timing belt tensioner assembly: roughly $70–$150
- Aftermarket timing belt tensioner (brands like Gates, Dayco, Conti, ACDelco, etc.): roughly $40–$100
- Timing belt tensioner kit (tensioner, sometimes bundled with a belt or other small items): roughly $120–$230
Prices can vary by Odyssey model year, engine variant, and regional market. Always verify fitment for your specific vehicle before purchasing.
Where to buy a timing belt tensioner
Choosing where to buy can affect price, availability, and warranties. The following options are common sources for this part.
- Honda dealership parts department (OEM): typically the safest fit and warranty, often at the higher end of the price range
- Auto parts stores (AutoZone, Advance Auto Parts, O'Reilly, NAPA): convenient and reliable for aftermarket options
- Online retailers and marketplaces (RockAuto, PartsGeek, Amazon): often the best prices and wide selection; check shipping and return policies
- Used or salvage yards (for shop or budget-minded buyers): lowest price but with variability in condition and limited guarantees
When buying online or used, confirm the exact part number and compatibility with your Odyssey’s year and engine to avoid fitment issues.
What to expect for installation and total cost
Installing a timing belt tensioner is a job typically done by a professional shop. The following gives a rough idea of labor costs and how they add to the part price.
- Typical labor time to replace the timing belt tensioner on a Honda Odyssey: about 2.5–4 hours, depending on engine and access
- Labor rate (varies by region and shop): roughly $75–$150 per hour
- Estimated total installation cost (labor only, parts not included): around $200–$500
If the service is done as part of a broader timing belt job (including belt replacement, water pump, and seals), total costs can rise to roughly $600–$1,000 or more, depending on parts and labor rates.
Summary
The cost to replace a timing belt tensioner on a Honda Odyssey varies widely with generation, brand choice, and where you buy. Plan for roughly $40–$180 for the tensioner part itself, plus $200–$500 in labor if done separately. If you opt for a full timing belt kit or add related components like a water pump, belt, or seals, total job costs will be higher. Always confirm compatibility with your specific Odyssey model year and engine before purchasing or scheduling service.
