Does the Lexus LS have a timing belt or chain?
The Lexus LS, Lexus' flagship luxury sedan, uses a timing chain rather than a timing belt in its engine. Timing chains are generally 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 typically made of reinforced rubber or a similar flexible material, while timing chains are made of metal links. Timing chains are generally more robust and can last the lifetime of the engine, while timing belts typically need to be replaced every 60,000 to 100,000 miles as part of regular maintenance.
Timing chains are also less prone to wear and tear, as they operate in an oil-lubricated environment within the engine. Timing belts, on the other hand, are exposed to the elements and can become cracked or worn over time, potentially leading to engine failure if they break.
Lexus LS Timing Chain
The Lexus LS, which has been in production since 1989, has always used a timing chain in its engines. This is a design choice that reflects Lexus' focus on reliability and longevity. By using a timing chain, Lexus can ensure that the LS's engine will continue to operate smoothly for many years and miles without the need for costly timing belt replacements.
Additionally, the use of a timing chain in the Lexus LS helps to reduce maintenance costs for owners, as they don't have to worry about scheduling a timing belt replacement service every few years. This can be a significant cost savings over the lifetime of the vehicle.
Conclusion
In summary, the Lexus LS uses a timing chain in its engine, which is a more durable and long-lasting solution compared to a timing belt. This design choice reflects Lexus' commitment to reliability and low maintenance costs for its flagship luxury sedan.
