The 2007 Lexus GS350 comes with a timing chain from the factory, which is more reliable than a timing belt. This is beneficial because the chain is designed to last the entire lifespan of your vehicle, typically around 150,000 to 200,000 miles for a Lexus GS350. The timing chain is usually covered under a ten-year, 100,000-mile warranty that will cover expenses for damages not caused directly by the driver. If you need to buy a new chain, parts alone can cost between $120 and $240. Hiring a mechanic or auto professional for replacement will require an additional payment of $130 to $240 for labor.
