Does A Toyota Sienna Have A Timing Belt Or Timing Chain?

Originally marketed as the “Camry of minivans”, the Sienna has long provided an excellent family van at an economical price to American families.

All Toyota Siennas from the 2007 model year to present are equipped with timing chains and interference engines while all Siennas prior to 2007 have timing belts that will require replacement and non-interference engines.

For example, the 2021 Toyota Sienna A25A-FXS 2.5L 4-Cyl Hybrid, 186 (gas only) hp / 243 (combined) hp option has a timing chain while the 2006 Toyota Sienna 1MZ-FE 3.3L V6 230 hp option has a timing belt.

Timing Belt Basics

The primary purpose of the timing belt or timing chain is to maintain the timing (syncronization) between the crankshaft and the camshaft(s).

A timing belt is made of a rubber compound while a timing chain is made of chain similiar to a bicycle chain.

A timing belt wears out over time and must be replaced at the manufacturer's specified interval. Timing belt failure can result in serious engine damage.

Although a timing chain will wear over time it is usually good for the lifetime of the engine but it should be routinely inspected.
