Does the 2014 Toyota Sienna come equipped with a timing belt or timing chain?

The 2014 Toyota Sienna is equipped with a timing chain, unlike a timing belt. You might be wondering about the advantages of having a timing chain instead. Timing chains are heavier and more intricate than timing belts, but they have a longer lifespan. Generally, timing chains do not need to be replaced regularly unless there is an issue. To prevent premature wear, stretching, and failure, regular oil changes are recommended. Replacing a timing chain is a complex task and can be costly in terms of labor. The average cost for a timing chain replacement on most cars ranges from $410 to $1040, or you can choose to purchase the parts separately for $90 to $250. Fortunately, timing chains typically only need to be replaced between 80,000 and 120,000 miles, so replacement is not common.
