Your 2005 Toyota Sienna uses a timing belt because Toyota only started using chains in the 2007 models. Signs that it's time to replace your timing belt include strange engine revving, exhaust problems, oil leaks near the engine, difficulty starting the motor, or a ticking noise from under the hood. Typically, timing belts should be changed every 60,000 miles or 10 years, whichever comes first. Labor costs can be around $600, with parts costing up to $400, but prices may vary depending on your location.
