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

In brief, the Acura TSX does not use a timing belt; it uses a timing chain. You won't replace a belt on this engine.

That means the question becomes about timing-chain service rather than a belt replacement. Costs vary by model year and engine variant, the shop you choose, and whether you replace the water pump or other related parts. The following guide explains what to expect and how to plan for a potential timing-chain repair.

Understanding the TSX’s timing system

Across model years, the TSX uses a timing chain instead of a timing belt. Because chains aren’t replaced on a fixed interval like belts, you typically don’t budget for a routine “belt change.” When a chain-related issue arises, repairs commonly involve the timing chain itself, tensioners, guides, and often the water pump, plus seals and gaskets as needed.

What’s involved when a chain service is performed? If a technician diagnoses worn tensioners or guides or a noisy chain, the repair kit or package usually includes the timing chain, guides, tensioner(s), water pump, and related seals. The exact components depend on the engine variant and year (for example, different K-series variants may have slightly different timing components).

• Timing chain, guides, and tensioner(s) as core replacement items or as part of a kit


• Water pump (often replaced at the same time, since it’s driven by the chain)


• Seals and gaskets around the timing cover and cam/crank seals


• Specialty tools and proper alignment procedures to verify valve timing

Conclusion: A timing-chain service is a major repair that focuses on chain components rather than a belt, and it’s not a routine maintenance item unless a failure occurs or it’s part of a larger overhaul.

Cost ranges for timing-chain service on the TSX

Prices vary by region, shop type, and whether the water pump and kit are included. The figures below reflect common ranges seen in the United States in 2024–2025.

• Independent auto shop or chain shop: roughly $800 to $1,500 for parts and labor, depending on whether the water pump is included and the local labor rate.


• Dealership or specialized Acura shop: typically $1,200 to $2,000 or more, particularly if labor time is high or diagnostic work is required.


• Additional costs: if seals, the water pump, or other related components need replacement beyond the chain kit, expect an extra $150 to $500 or more.

Note: These are ballpark estimates and can vary by year/engine variant, location, and shop. Always obtain a written estimate before any work begins.

What affects price

Key factors include the exact engine variant, whether the water pump is included, whether a timing kit includes updated guides, local labor rates, and the shop’s overhead. Because timing-chain work is typically more labor-intensive than a belt replacement, prices reflect the complexity of the job.

Signs you may need timing-chain service

Not every TSX will ever require a timing-chain replacement, but certain symptoms warrant a professional diagnosis. A mechanic can confirm whether a chain issue is present and outline a repair plan.

• Loud, metallic rattling or tapping from the front of the engine, especially on startup or at cold temperatures


• Check engine light or codes related to timing, misfire, or sensor readings


• Rough running, loss of power, or engine misfires without a clear external cause


• Oil leaks around the timing cover or signs of oil leaks near the front of the engine

Conclusion: If you hear a chain-related noise or experience performance issues, have the vehicle inspected by a qualified technician. Do not assume a belt replacement is needed on the TSX.

Questions to ask your mechanic

To ensure you get a clear diagnosis and a fair estimate, consider asking these questions before authorizing work:

• Does my engine use a timing belt or timing chain, and is a chain service actually required?


• What exactly is in the proposed timing-chain kit, and is the water pump included?


• Will you inspect for accompanying issues (oil leaks, seals, guides, tensioners) and replace them if needed?


• What is the expected labor time, and can I have a written, line-item estimate?

Conclusion: Clarifying the scope and parts involved helps avoid surprises and ensures you’re paying for the right service.

Summary

The Acura TSX does not use a traditional timing belt; it uses a timing chain, so “belt replacement” is not a common service for this model. When a timing-chain service is needed, costs typically range from about $800 to $2,000 or more depending on engine variant, whether the water pump and additional seals are replaced, and local labor rates. Always obtain a detailed estimate and have a qualified technician diagnose any chain-related noises or performance problems. With proper diagnosis and planning, you can manage the costs and ensure the job is done correctly.

Is it worth replacing a timing belt?

These car parts are subject to great forces inside the vehicle's engine. For this reason, every vehicle that has a timing belt will require a new timing belt replacement at some point during its life. Without a fully functioning timing belt, the car's engine won't be able to run properly.

How much does Acura charge for timing belt replacement?

The cost to replace your Acura MDX timing belt will vary depending on your MDX's model year, but is often in the neighborhood of $1,100 - $1,700. While a somewhat pricey repair, you luckily don't have to get the timing belt replaced often.

How much does it cost to replace a timing chain on a Acura TSX?

The cost to replace the timing chain on an Acura TSX typically ranges from $1,800 to $2,700, with the majority of the cost being labor. While the parts themselves may cost around $750, the labor can be between $1,300 and $1,900, depending on the specific year of the car and the complexity of the job. Some estimates for a 2010 TSX specifically mention a range of $1,800 to $2,200. 
Cost breakdown

• Total Cost: $1,800 - $2,700
• Parts: Approximately $750
• Labor: Approximately $1,300 - $1,900 

Factors that influence cost

• Vehicle Year: The specific model year of the TSX can affect the price due to variations in engine design and labor hours required. 
• Shop Labor Rates: Rates vary between different mechanics and dealerships. 
• Additional Parts: The repair may also require replacing other components, such as the VTEC actuator solenoid, which would add to the total cost. 

Why replacement is necessary

• Timing chains are designed to last the life of the engine, unlike timing belts, so they are only replaced if there is a problem. 
• Signs of a failing timing chain include rattling noises, engine misfires, sputtering, and warning lights on the dashboard. 
• A failure can be catastrophic and lead to major engine damage. 

What year acura tsx to stay away from?

Years to potentially avoid for the Acura TSX include 2004, 2005, 2006, 2009, 2010, and 2012 due to common issues like transmission problems, AC compressor failures, and higher rates of complaints compared to other years. While other years have had their share of problems, these are the ones most frequently cited as problematic. 
Model years to potentially avoid

• 2004-2006: First-generation models with potential issues like AC compressor failure and power steering leaks. 
• 2009: A model year with a significant number of recalls and complaints, particularly concerning steering and suspension systems. 
• 2010: This year has the highest number of complaints reported, according to some sources, with a high number of recalls. 
• 2012: This year is also highlighted as having issues that appear at lower mileages and result in higher repair costs. 

Years with fewer reported issues 

• 2007: This year is frequently mentioned as one of the best due to its low number of reported complaints. 
• 2013-2014: These years are also highly rated for reliability and have fewer reported problems.
