Does the 2006 Acura TSX have a timing belt?
No. The 2006 Acura TSX uses a timing chain, not a timing belt. The US-market TSX of that year is equipped with a 2.4-liter K24A2 inline-4 engine and a chain-driven timing system. Timing chains are designed to last the life of the engine under normal maintenance, avoiding the periodic belt-replacement interval common to some older engines.
Engine and timing mechanism
Understanding how the TSX's engine is set up helps explain why a belt is not used. The 2006 TSX relies on Honda’s K-series timing-chain approach, which typically requires less frequent replacement than timing belts. Below are the core facts you should know about this configuration:
- Engine: 2.4L K24A2 DOHC i-VTEC
- Timing mechanism: Chain-driven, not belt-driven
- Maintenance expectation: No scheduled timing-belt interval; the chain is designed to last for the engine's life under normal driving conditions
- Wear items to monitor: Timing chain tensioner and guides can wear over time; chain failures are uncommon but can occur if lubrication or maintenance is neglected
In short, the 2006 TSX’s timing chain setup means fewer belt-change concerns, but it still relies on proper engine maintenance to prevent wear-related issues over the long term.
Practical considerations for owners and buyers
For current owners or prospective buyers, here are practical notes about the timing system and what to watch for:
- Listen for unusual rattling or clattering on cold startup, which can indicate tensioner or chain wear
- Maintain regular oil changes with the grade and interval recommended in the owner’s manual to keep the chain tensioner lubricated
- If buying used, review service history for any timing-system work or unusual engine noises, though chain replacement is not a routine item like belt jobs
- Be aware that while there is no belt replacement schedule, a chain issue typically manifests as noise or engine performance problems and should be diagnosed by a qualified mechanic
Overall, the chain-driven timing system in the 2006 TSX reduces belt-related maintenance but places importance on standard engine care, especially oil health and regular service intervals.
Summary
The 2006 Acura TSX uses a timing chain rather than a timing belt. This setup typically requires less frequent maintenance related to the timing system, with emphasis placed on regular oil changes and vigilant listening for engine noises. For most drivers, there is no belt-change interval to worry about, but attentive maintenance remains essential to keep the chain and related components functioning properly over the vehicle’s lifespan.

Does the 2006 Acura TSX have a timing belt or chain?
The 2006 Acura TSX uses a timing chain, not a timing belt. This is because the TSX is equipped with a 4-cylinder engine, which features a metal timing chain instead of a rubber belt. Timing chains are generally more durable and do not have a set replacement interval, though they can stretch and require replacement if issues arise, says Reddit users.
- Timing Chain: The TSX's 2.4L four-cylinder engine uses a timing chain.
- Durability: Timing chains are made of metal and are designed to last longer than rubber timing belts, sometimes outlasting the life of the engine.
- Replacement: Unlike timing belts that have a recommended replacement interval (e.g., every 100,000 miles), timing chains do not.
- Maintenance: Regular oil changes are crucial for the longevity of the timing chain.
- Warning Signs: A rattling noise, especially on a cold start, can indicate a stretched chain and should be addressed immediately by a mechanic.
