Does the 2013 Lexus ES 350 have a timing belt or chain?

The 2013 Lexus ES350 has a timing chain, but not a timing belt. This is considered a good thing, because when a car has a timing chain, it is usually guaranteed for the lifetime of the vehicle. That means if anything happens to cause wear or damage that is outside of Your control, Lexus will replace the chain free of charge. A timing belt, however, requires regular maintenance and replacements at the same times that other things like fluids are replaced and checked. In the long running, having a belt instead of a chain will increase the cost of Your yearly vehicle maintenance.
