How long do timing belts last on an Acura TL?

Typically about 105,000 miles or seven years for belt-driven Acura TL engines; always check your specific model year in the owner’s manual or with a dealer. If your TL uses a timing chain instead of a belt, there is no regular belt replacement interval to follow.

What determines the timing belt replacement interval

Engine design, operating conditions, and maintenance practices all influence how long a timing belt lasts. For most Acura TL models that rely on a conventional timing belt, manufacturers commonly set a replacement window around the 105,000-mile mark or seven years, whichever comes first. Extreme heat, high mileage in short trips, or oil leaks can shorten belt life, so owners may opt for earlier service in demanding conditions.

Below is a general guideline for belt-driven TL engines. Always confirm with your vehicle’s documentation or a certified technician, as intervals can vary by year and market.

Typical replacement interval for belt-driven Acura TL engines:



• About 105,000 miles or seven years, whichever comes first, under normal driving conditions.

After reviewing the belt’s replacement schedule, plan for proactive maintenance to avoid a roadside risk. If you’re unsure about your specific TL model, consult the owner’s manual or a dealer for the exact interval.

Signs your timing belt may be nearing end of life

In addition to mileage and age, certain warning signs can indicate a belt is deteriorating and may need replacement sooner than the standard interval.

• Visible cracking, fraying, or missing teeth on the belt;


• Glossy or glazed belt surface indicating glazing from slipping;


• Oil leakage that contaminates the belt;


• Squealing, chirping, or unusual belt noises from the engine bay;


• Engine misfires, trouble starting, or rough running that coincides with belt wear;


• Loss of engine timing leading to reduced performance or stalling (in severe cases if the belt fails).

If you notice any of these signs or if your vehicle is approaching the typical 105,000-mile window, schedule a professional inspection promptly. A failed timing belt can cause severe engine damage, especially in interference engines like many Acura V6 setups, making preventative replacement a prudent choice.

What to do now

To minimize risk and avoid costly repairs, plan ahead for timing belt service as your Acura TL approaches the recommended interval. Consider the following steps when you reach the planned mileage window or notice wear signs.

• Schedule a timing belt replacement with a qualified technician; many shops will also replace the water pump and idler/tensioner pulleys at the same time since they’re accessed during the belt service.


• Prepare for the cost range, which varies by location and whether other parts (water pump, seals) are replaced concurrently.


• Keep records of belt service to track future maintenance and ensure you stay on schedule.

In short, staying ahead of the timing belt schedule for your Acura TL is critical to engine reliability. If in doubt, a dealer or trusted independent shop can verify whether your model uses a belt and what the exact interval should be.

Summary

For most belt-driven Acura TL engines, a timing belt replacement around 105,000 miles or seven years is the standard guideline, though exact intervals depend on the model year and driving conditions. Regular inspection and prompt service if wear signs appear are essential to prevent catastrophic engine damage. Always consult the owner’s manual or a certified technician to confirm the correct interval for your specific TL.

Are there warning signs of timing belt failure?

Symptoms of a bad timing belt include unusual engine noises like ticking or squealing, engine misfires, poor performance such as rough idling and hesitation, and the check engine light coming on. Other signs can be difficulty starting the engine or oil leaks from the front of the engine. If the belt fails completely, the engine will stop running.
 
Noises

• Ticking or clanking: A ticking or clanking sound coming from the front of the engine can indicate a worn-out belt. 
• Squealing or whirring: A high-pitched squeal, especially when starting the engine or accelerating, can be a sign of a loose or degraded timing belt. 

Engine performance issues

• Misfires: The engine may misfire due to the belt's timing being off. 
• Rough idling: The engine may feel like it's struggling to find a consistent rhythm when idling. 
• Hesitation or jerking: You may feel hesitation or jerking when you accelerate. 
• Loss of power: The vehicle may feel sluggish, and you might experience a noticeable drop in power. 
• Stalling: The engine may stall out, either while driving or while idling. 
• Difficulty starting: The engine may crank but fail to start, or it may not turn over at all. 

Other symptoms

• Check engine light: The check engine light on your dashboard can illuminate to signal various engine timing issues. 
• Oil leaks: Leaks of oil from the front-side of the engine where the belt is located can indicate a problem. 
• Excessive engine vibrations: You might notice more vibration than usual coming from the engine. 

What to do
If you experience any of these symptoms, it is best to have a mechanic inspect your timing belt. Ignoring a failing timing belt can lead to catastrophic engine damage, especially on "interference engines" where the valves and pistons can collide if the belt breaks.

How often should I replace the timing belt on my Acura TL?

So, when do you need to get a new timing belt? While there's no telling exactly how long a timing belt should last, many automotive experts suggest getting a new timing belt installed after around every 60,000 to 100,000 miles.

How much does it cost to replace a timing belt on a Acura TL?

The cost to replace an Acura TL timing belt typically ranges from $409 to over $2,250, with the final price depending heavily on the shop and what parts are replaced. Independent mechanics may charge around $850 to $1,300, while Acura dealerships are often more expensive, sometimes reaching $1,500 to over $2,250 for parts and labor. The price includes the belt, labor, and often other components like the water pump, tensioner, and pulleys, which are frequently replaced at the same time. 
Cost breakdown

• Labor is the main cost: Replacing the timing belt is labor-intensive, as many parts must be disassembled to access it. 
• Parts matter: The cost of the replacement kit, which may include the water pump, tensioner, and pulleys, can add to the total. 
• Shop type affects price:
  • Independent repair shops: Generally offer lower prices, with estimates in the $850 to $1,300 range. 
  • Acura dealerships: Typically have higher prices, but may use manufacturer-approved parts and offer additional services like loaner cars and full vehicle inspections. 

What to consider when getting a quote

• Get multiple quotes: It's best to get quotes from several independent shops and one dealership to compare costs. 
• Clarify what's included: Make sure the quote includes the timing belt, water pump, tensioner, and all related seals and pulleys. 
• Ask about parts quality: Inquire about the brands of parts being used and ask about the warranty on parts and labor. 

Can a Honda timing belt last 150,000 miles?

Replace it on time to avoid engine damage. Rubber ages even if you don't drive much. For many Honda models with timing belts, a practical rule is about 105,000 miles or 7 years, whichever comes first. Some severe-use or hot/cold climates call for shorter intervals; older Honda manuals list time-based limits as well.
