How much to replace an Acura MDX timing belt?
Typically, a timing belt replacement for an Acura MDX costs about $800–$1,200 at an independent shop, or $1,200–$1,800 at a dealership. Real price depends on year, location, and whether the water pump is included in the kit.
For most MDX models with the 3.5-liter V6 that use a timing belt, the service involves replacing the belt along with related components and fluids. The common replacement interval is around 105,000 miles or roughly seven years, though you should verify the exact interval in your owner's manual for your model year. The work is typically performed as a packaged service that may include the water pump, tensioners, idlers, seals, and coolant, all of which affect the final price.
What affects the price
Prices are influenced by several factors, including parts selection, labor rates, and whether the service is performed at a dealer or an independent shop. The main cost drivers are listed below.
- Parts included in the kit (belt, water pump, tensioners, idlers, seals, coolant) and whether OEM or aftermarket components are used
- Labor rate and shop type (dealer vs. independent shop)
- Model year and engine variant (some MDX years use slightly different belt kits)
- Geographic region and any applicable taxes or shop fees
- Whether additional items are bundled into the service (e.g., coolant flush, cam/crank seals)
In practice, most quotes reflect a bundled package that includes the belt kit and labor. If the water pump or seals aren’t included, the price will be lower upfront but may cost more later if a failure occurs.
What to expect when you shop for quotes
To minimize surprises, ask for a written estimate that itemizes parts and labor, and watch for the following details in the quote.
- Whether the water pump is included in the kit and its cost
- Estimated labor hours and the shop’s hourly rate
- Warranty terms on parts and labor
- Any extra items that might be needed (cam seals, crank seals, additional coolant)
Request quotes from multiple shops (at least two or three) and review their customer feedback. Schedule the service for a time that works with your calendar, as the job typically takes a few hours at a general repair shop.
Important considerations for MDX timing belt service
Because the MDX’s 3.5L V6 is an interference engine, a broken belt can cause serious valve damage. If your vehicle is approaching the recommended interval or you notice signs of wear—such as squealing from the belt area, coolant leaks near the belt, or poor engine performance—arrange service promptly to prevent costly repairs.
Overall, timing belt replacement is a routine maintenance item that helps protect the engine. Using quality parts, ensuring proper torque and alignment, and confirming a clear, written quote will help you get the best value for your MDX.
Summary
For most Acura MDX models with a belt-driven 3.5L V6, expect about $800–$1,200 at an independent shop and $1,200–$1,800 at a dealership, with the water pump often included in the kit. Labor typically spans 3–6 hours, depending on the shop and year. Always confirm whether the pump, seals, and coolant are included in the quoted price, and verify the recommended interval in your owner's manual. Because the engine is interference-rated, timely replacement is a prudent safeguard against expensive valve damage.
