Does Acura TSX use timing belt or chain?
The Acura TSX uses a timing chain, not a timing belt.
The TSX has two US-market generations (2004–2008 and 2009–2014) that rely on a 2.4-liter i-VTEC four-cylinder engine. In both generations, Acura chose a chain-driven timing system, a design that generally reduces maintenance tasks compared with belt-driven engines. Regular oil maintenance remains essential to keep the chain and tensioner operating cleanly.
Engine lineup and timing system
The TSX’s powertrains are built on Honda/Acura’s K-series 2.4-liter engines and, in both generations, use a timing chain rather than a belt. The change from the first to the second generation was stylistic and drivetrain-focused rather than belt-related.
Key engine variants and timing system:
- 2004–2008 TSX: 2.4L i-VTEC four-cylinder (K-series)
- 2009–2014 TSX: 2.4L i-VTEC four-cylinder (K-series)
In both cases, the timing chain drives the camshaft(s) with a chain tensioner and guides, eliminating the need for routine timing belt replacements.
Implications for owners
Because the TSX uses a timing chain, there is no fixed mileage interval for replacing a timing belt. The main maintenance considerations are keeping the engine oil clean and at the proper level, as poor lubrication can accelerate wear on the chain tensioner and guides. If you hear a rattling or metallic noise from the front of the engine, have the timing area inspected promptly to avoid potential damage.
What to watch for
Typical warning signs of timing-chain-related trouble include startup rattle, ongoing chain noise, or unusual engine performance issues. Regular oil changes at the recommended interval help preserve chain integrity. If you suspect a problem, a mechanic can perform a chain-tensioner inspection, oil pressure test, and, if needed, timing-chain service.
Summary
In short, the Acura TSX relies on a timing chain for its four-cylinder engines, not a timing belt. This design choice reduces the need for belt-change maintenance and aligns with Honda/Acura’s long-life timing-chain philosophy, though it still depends on proper oil maintenance and periodic inspection of the chain and tensioner components.
Does the Acura TSX have a timing belt or chain?
The 4-cylinder Acura TSX has a timing chain, while the V6-equipped models use a timing belt. Timing chains are designed to last the life of the vehicle and don't have a set replacement interval, but they can require service if they become stretched or make noise.
4-cylinder models (2.4L engine)
- Component: Timing chain
- Maintenance: Chains are generally very durable and require no scheduled maintenance. However, regular oil changes are crucial for longevity.
- Problem signs: A rattling noise, especially on a cold start, can indicate a worn or stretched chain or a problem with the tensioner.
V6 models (3.5L engine)
- Component: Timing belt
- Maintenance: These models require timing belt replacement at specific mileage or time intervals, just like other cars with timing belts.
- Problem signs: A failing timing belt can cause a range of symptoms, including engine issues or complete failure.
How much does it cost to replace a timing chain on a TSX?
The average cost for an Acura TSX Timing Chain Tensioner Replacement is between $636 and $764. Labor costs are estimated between $274 and $402 while parts are typically priced around $362.
Which Acura models have timing chains?
If you own a late model Acura vehicle that has a 4 cylinder engine, then it does not have an Acura timing belt, but instead it utilizes a timing chain. Late model Acura vehicles that use a timing chain include the Acura TSX (4 cylinder models only), the Acura RSX, the Acura ILX, and the Acura RDX.
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.
