How much does it cost to replace a timing belt on a 2006 Lexus ES330?
In the U.S., you should expect to pay roughly $600 to $1,400 for a timing belt replacement on a 2006 Lexus ES330, depending on whether you replace the water pump and other components, and where the work is performed.
The 2006 ES330 uses a 3.3-liter V6 engine (1MZ-FE) that relies on a timing belt rather than a timing chain. Replacing this belt is a major maintenance item typically recommended around 90,000 to 100,000 miles. Because the water pump and other belt-driven components are accessed during this job, many shops either include or strongly suggest replacing them at the same time to minimize future labor costs and avoid repeat service.
What goes into the price
Pricing reflects parts, labor, and any ancillary services. Below is a breakdown of typical components and cost ranges you may see.
- Parts: timing belt kit (belt, tensioner, idlers), water pump usually included, seals, and coolant. Depending on the kit and whether OEM parts are used, parts can range from about $100 to $400+ for the kit, and $50 to $300 for a water pump.
- Labor: labor charges vary by shop and region, commonly 2.5–5 hours for the ES330, at roughly $75–$150 per hour, totaling about $200–$750.
- Additional services: coolant flush, thermostat replacement, or gasket/seal replacements may add $50–$200.
In practice, many customers end up paying between about $700 and $1,200 when including a water pump and full kit at an independent shop; dealer pricing or shops in high-cost areas can push toward $1,400 or more.
Cost ranges by source
Where you have the work done makes a big difference. Here are typical ranges by service channel.
- Independent auto repair shop: Typically $600–$1,000 for belt-only or $800–$1,500 when including water pump and thermostat.
- Dealership/authorized Lexus shop: Typically $900–$1,500, sometimes more in high-cost regions.
- DIY risk: If you have the tools and expertise, replacing a timing belt yourself could save on labor, but you risk catastrophic engine damage if the job is done incorrectly.
Note: DIY is generally not recommended for this engine unless you have timing belt replacement experience due to the risk of engine damage if the belt is misinstalled.
What to ask your mechanic
Before committing, ask about parts, warranty, and what’s included. Clarify whether the water pump, timing belt kit, tensioners, seals, coolant flush, and thermostat are included, as well as the warranty on parts and labor.
- Is OEM or aftermarket parts used, and what are the price differences?
- What is the expected labor time and warranty on the service?
- Will the service include a coolant flush and thermostat replacement if needed?
Having clear estimates and a written warranty helps prevent surprises when you pick up the car.
Summary
Replacing the timing belt on a 2006 Lexus ES330 typically costs between $600 and $1,400, depending on whether a water pump and other parts are included, plus regional labor rates. All-in-one kits with pump plus labor in an independent shop generally fall between $800 and $1,200, with dealer pricing often higher. Plan ahead and factor in maintenance scheduling at around 90,000–100,000 miles to avoid belt breakage and potential engine damage.
