The 2015 Toyota Tundra with a 5.7 liter engine features a timing chain instead of a timing belt. This chain is built to last the entire lifespan of the vehicle because it is made of metal, making it more durable. Unlike belts, chains don't crack or dry out since they are internal components of the engine. Additionally, they can contribute to better fuel efficiency. While most timing belts require replacement every 60,000-100,000 miles, the Tundra's timing chain is expected to be maintenance-free. However, in rare cases, the chain may break or its tensioners may stretch, leading to potential serious damage to the engine. If you notice metal shavings in the oil, encounter misfires, or hear unusual rattling sounds when idling, it’s important to have these issues inspected by a trustworthy auto repair shop.
