Does the 2007 Toyota Sienna come equipped with a timing belt or timing chain?

Question

Accepted Answer

The 2007 Toyota Sienna comes with a timing chain, which is meant to last the entire lifespan of the vehicle unlike a belt that requires regular replacement. This essential part in the engine consists of links that synchronize the camshaft and crankshaft, controlling the valves that regulate each cylinder's firing. If the timing chain breaks, it can lead to costly damage. If you notice a rattling noise in the engine area, it could indicate that pieces of the chain have broken off and fallen into the oil drain pan due to friction. This warning sound should not be ignored. If you perform your own oil changes, be on the lookout for metal shavings in the oil. The average cost for replacing the timing chain in a 2007 Sienna typically ranges from $2,090 to $2,570, which includes the cost of labor.
