Does 2012 Toyota Sienna has a timing chain?

The 2012 Toyota Sienna is equipped with a timing belt, not a timing chain. It is important to follow the manufacturer's recommended maintenance schedule for replacing the timing belt to avoid potential engine damage. Unlike a timing chain, which typically lasts longer and may not need regular replacement, a timing belt usually requires replacement around 60,000 to 100,000 miles. Always consult the owner's manual for specific maintenance guidelines.
