The typical cost to replace the timing belt on a 2006 Toyota Sienna is about $800–$1,200, depending on parts and labor. In some cases, especially in high-cost areas or when adding a water pump, the price can reach around $1,400 or more.
The final price depends on several factors, including regional labor rates, whether a water pump and other components are replaced, and the quality of parts (OEM vs aftermarket). Dealer service centers generally charge more than independent shops, and taxes or disposal fees may apply. This article breaks down the elements that influence price and how to obtain reliable quotes.
Cost factors
Several factors influence the final quote. Here's what typically drives the price.
- Regional labor rates and the type of shop (dealer vs. independent)
- Whether the water pump is included in the timing belt kit
- Quality and source of parts (OEM vs aftermarket)
- Whether tensioners, idler pulleys, seals, and thermostat are replaced
- Additional fees such as diagnostics, fluids, disposal, and warranties
Understanding these factors helps you compare quotes accurately and avoid surprises.

What's the worst year for Toyota Sienna?
Siennas are generally reliable, and it's difficult to identify the worst years. The 2004 model year—the first of the second generation—has received the most complaints from owners, and the 2017 Toyota Sienna is also one to avoid due to transmission issues—keep an eye out for them during a test drive.
Is it worth fixing a timing belt on a car?
More critically, most vehicles on the road today are equipped with interference engines—where the clearance between valves and pistons is minimal. If the timing belt breaks while driving, the pistons can collide with open valves, causing severe engine damage that requires expensive repairs or engine replacement.
