Does the 2014 Toyota Sienna have a timing belt or chain?

The 2014 Toyota Sienna has a timing chain. But what are the benefits of having a timing chain over a timing belt You may be asking Yourself. Timing chains are heavier and more complex than timing belts, but they also last much longer. Really, unless there's a problem, timing chains don't have a replacement interval. Regular oil changes prevent premature wear, stretching, and failure.Replacing the timing chain is a complicated job, and the labor costs can be quite high. For most cars, a timing chain replacement costs between $410 and $1040, or You can order the parts themselves for $90 and $250. Luckily the timing chain normally only needs to be replaced between 80,000 and 120,000 miles making it rare to replace it.
