Does a Lexus IS350 have a timing belt or chain?
The Lexus IS350 uses a timing chain, not a timing belt. Timing chains are generally more durable and longer-lasting than timing belts, requiring less frequent replacement.
Timing Belt vs. Timing Chain in the Lexus IS350
The Lexus IS350 is equipped with a 3.5-liter V6 engine, which utilizes a timing chain rather than a timing belt to synchronize the opening and closing of the engine's valves. Timing chains are metal components that connect the crankshaft to the camshafts, whereas timing belts are made of reinforced rubber or composite materials.
Timing chains have several advantages over timing belts in the Lexus IS350:
- Durability: Timing chains are generally more durable and can last the lifetime of the engine with proper maintenance, while timing belts typically need replacement every 60,000 to 100,000 miles.
- Reliability: Timing chains are less prone to wear and breakage compared to timing belts, reducing the risk of engine damage if the timing system fails.
- Maintenance: Timing chain replacement is less frequent and often less expensive than timing belt replacement.
The use of a timing chain in the Lexus IS350 is a design choice that prioritizes long-term reliability and reduced maintenance costs for the owner.
Can a timing chain last 200 000 miles?
Timing chains can last anywhere between 150,000 and 200,000 miles before they require repair or sustain damage. But once they do, they must be replaced without fail as they can break off entirely, therefore causing the engine to fail.

Can a timing chain last 300000 miles?
However, the timing chain isn't necessarily a maintenance item and can last the engine's life, provided you change the oil regularly and maintain the rest of the engine. Modern engines can last 300,000 miles or more with proper maintenance, and the timing chain can go that long, too.

Are timing chains better than belts?
Which Is Better? Though it's certainly a matter of opinion that's based largely on your priorities, it's generally felt that timing chains are better than timing belts. While most timing belts are supposed to be replaced every 60,000 to 120,000 miles, many timing chains end up lasting the life of the car.
