Does the LS460 have a timing belt or chain?
The Lexus LS460 uses a timing chain, not a timing belt. Timing chains are more durable and longer-lasting than timing belts, requiring less frequent replacement.
Timing Belt vs. Timing Chain
The primary difference between a timing belt and a timing chain is the material they are made of. Timing belts are made of reinforced rubber or a similar flexible material, while timing chains are made of metal links. This makes timing chains more robust and resistant to wear and tear over time.
Timing belts typically need to be replaced every 60,000 to 100,000 miles as part of regular maintenance, while timing chains can often last the lifetime of the engine without needing replacement. Timing chains are also less prone to slipping or breaking, which can cause serious engine damage if a timing belt fails.
The Lexus LS460 Timing Chain
The Lexus LS460, which was produced from 2006 to 2017, uses a timing chain in its 4.6-liter V8 engine. Lexus engineers opted for a timing chain design to provide greater reliability and longevity for this high-end luxury sedan.
Unlike a timing belt, the timing chain on the LS460 does not need to be replaced as part of regular maintenance. As long as the engine is properly maintained, the timing chain should last for the entire lifespan of the vehicle without issue.
Benefits of a Timing Chain
- Longer lifespan: Timing chains can last for hundreds of thousands of miles, whereas timing belts typically need replacement every 60,000 to 100,000 miles.
- Lower maintenance costs: Replacing a timing belt is a more involved and expensive procedure than replacing a timing chain.
- Improved reliability: Timing chains are less prone to slipping or breaking, which can cause catastrophic engine damage.
Overall, the use of a timing chain in the Lexus LS460 is a testament to the brand's commitment to engineering high-quality, durable vehicles. The timing chain design helps ensure the LS460's engine will continue to perform reliably for many years of ownership.
