The 2008 Toyota Sienna is equipped with a timing belt, not a timing chain. It's important to follow the manufacturer's recommended maintenance schedule for replacing the timing belt, typically around 90,000 miles, to avoid potential engine damage. Regular inspections can help ensure the timing belt remains in good condition.
