Does the 2000 Toyota Sienna have a timing belt or chain?

The 2000 Toyota Sienna is equipped with a timing belt. Unlike a chain, which is designed to last the life of the vehicle, a belt needs to be replaced routinely. This part is made of rubber and features teeth along the side. These teeth turn the camshaft and crankshaft sprockets, keeping them perfectly synC-HRonized. This is important because it ultimately controls the opening and closing of intake and exhaust valves. If it breaks, expensive engine damage can be resulted. Symptoms of a failing timing belt include ticking noise, engine won't turn over, mIS Fires, check engine light is on, exhaust issues, high RPM, and general performance issues. Toyota recommends replacing this part every 90,000 miles. The average cost to have the belt replaced in the 2000 Sienna is $690 to $970. Labor accounts for $460 to $580 of that total.
