Does the 2015 Toyota Sienna have a timing belt or chain?

The 2015 Toyota Sienna will be powered by a 3.5L 2GR-FE V6 engine that will run on a timing chain system. All models of this vehicle starting in a 2007 have used a timing chain instead of a timing belt. These are meant to last the lifetime of the vehicle and will not likely need to be replaced unless some major damage occurs to the vehicle such as being part of an accident. If You do find Yourself in this situation and need to replace the chain You will be looking at spending between $190 and $320 for an entire new chain kit. This is a difficult task so most will want to take their vehicles in to a mechanic to do the job and You can expect to spend between $450 and $950 in total labor and parts for this job.
