When should Acura timing belt be replaced?
If your Acura uses a timing belt, you should plan its replacement by mileage or age, typically by 60,000 to 105,000 miles or roughly every 5 to 7 years, whichever comes first. If your engine uses a timing chain, there isn’t a scheduled belt replacement interval.
Understanding the timing belt schedule depends on the engine family and model year. Acura has shifted many newer engines to timing chains, which do not require a routine belt replacement, but some older or specific engines still rely on belts. This article explains the current guidance and how to determine the exact interval for your vehicle.
What determines the replacement schedule
Replacement timing is driven by whether your engine uses a belt or a chain, plus miles driven and the vehicle’s age. Belts age and dry out over time, even if mileage is low, so age can trigger replacement earlier than the mileage limit. Chains, by contrast, usually last longer and have different service considerations.
Belts versus chains explained
A timing belt is a rubbery belt with teeth that synchronizes the camshaft and crankshaft. A timing chain is a metal chain that serves the same purpose but generally lasts longer and may not have a fixed mileage interval. If you’re unsure which your Acura uses, check the owner’s manual or confirm with a dealer or qualified mechanic.
Typical replacement intervals
The following ranges are common guidance for belt-driven Acura engines. Always verify the exact interval for your specific model and engine family with the manual or a dealer.
- 60,000 miles (96,500 km): A common lower bound for many older belt-driven engines.
- 90,000 miles (145,000 km): A frequently cited target interval for many belt-driven Honda/Acura engines.
- 105,000 miles (169,000 km): Some engines specify replacement near this mileage.
Because belts can deteriorate with age, many schedules also call for replacement every 5–7 years regardless of mileage, particularly in regions with extreme temperatures or humidity.
What to do if you’re unsure
If you aren’t sure whether your Acura uses a belt or a chain, or you can’t locate the interval in the manual, follow these steps:
- Check the owner’s manual maintenance schedule for “timing belt” or “timing chain” and the replacement interval.
- Identify your engine type by code (often stamped on the engine) and confirm belt vs. chain with a dealer or mechanic.
- Inspect the belt for visible wear if accessible (cracks, fraying, missing teeth, or oil contamination indicate replacement is overdue).
- Obtain a professional inspection and quote from a dealer or shop, including related components commonly replaced with the belt (water pump, tensioner, idlers).
Taking proactive steps can prevent costly engine damage caused by timing belt failure, which is more severe in interference engines.
Summary
In short, belt-driven Acura engines typically require replacement between 60,000 and 105,000 miles or about every 5–7 years, whichever comes first. Many newer Acura models use timing chains, which do not have a scheduled belt replacement. Always verify the exact interval for your vehicle in the owner's manual or with a dealer, and plan to replace the belt along with associated components when due.
