How much does it cost to replace a timing belt on a Acura RDX?
There is no timing belt to replace on modern Acura RDX models; they use a timing chain. This means you won’t see a standard timing-belt replacement price in routine maintenance. If you’re thinking about belts more generally, the drive belt (serpentine belt) is a separate component that can wear, and timing-chain issues, while rare, can require expensive service.
What kind of timing system does the RDX use?
In recent generations, the Acura RDX uses a timing chain rather than a belt. Timing chains are designed to last longer and typically don’t have a fixed replacement interval. However, wear can occur on the chain’s tensioners or guides, which may require service in high-mileage or harsh-driving conditions. Because of this, the routine maintenance schedule does not include a timing-belt replacement for these models.
Note on older or unusual configurations
Very early or non-standard engine variants could differ, but for the current-generation RDX, a timing-belt replacement is not part of the normal maintenance plan. If you own a much older RDX or a different engine setup, check the owner’s manual or consult a dealer for the exact component layout.
Cost considerations you’re likely to encounter
Prices below reflect typical U.S. market ranges as of 2024-2025 and can vary by model year, region, and shop.
- Serpentine (drive) belt replacement: typically around 150 to 350 USD total, depending on labor rates, parts, and whether other components like the tensioner are replaced at the same time.
- Water pump replacement when done with the belt: an additional 200 to 600 USD, depending on whether it’s replaced concurrently and on labor rates.
- Timing chain tensioner/guide service (rare): for labor-intensive repairs, expect roughly 800 to 2,500 USD or more, depending on engine access and parts required.
Bottom line: for a modern Acura RDX, you won’t pay a traditional timing-belt replacement price. If a shop mentions a timing belt for a current RDX, they’re likely referring to the serpentine drive belt or may be mislabeling a chain-related service. Always request a written estimate that itemizes parts and labor before authorizing any work.
What to expect when shopping for service
When planning maintenance or unexpected repairs, here’s what to keep in mind. The belt-related costs you see are usually for the serpentine belt, while true timing-chain work is much less frequent and more expensive when it occurs. Always compare multiple quotes and ask for the exact component being replaced to avoid confusion.
Summary
Modern Acura RDX models rely on a timing chain rather than a timing belt, so there is no standard timing-belt replacement cost to budget for. If you’re maintaining your vehicle, plan for serpentine-belt wear and note that timing-chain-related repairs are uncommon but can be expensive if needed. For the most accurate estimate, consult your dealer or a trusted independent shop and verify the exact engine configuration for your vehicle year.
