Does the Lexus ES 350 have a timing belt?

No. The Lexus ES 350 uses a timing chain on its 3.5-liter V6 (2GR-FE) rather than a timing belt. This design means there isn’t a scheduled belt replacement like you might find with some other engines. The article below explains what that means for maintenance, model years, and ownership.

Engine and timing system fundamentals

Understanding how the ES 350 is powered helps clarify why a timing belt question is often moot. The ES 350’s 3.5L V6 is driven by a timing chain, not a belt. Timing chains are generally designed to last the life of the engine, provided the engine receives regular maintenance and the chain tensioners, guides, and related components remain in good condition. This setup differs from many engines that rely on belt-driven timing with explicit replacement intervals.

Key points about the ES 350’s timing system include:

• The ES 350 uses a timing chain, not a timing belt, for the 2GR-FE V6 engine.


• A timing chain is designed for long life, with replacement typically only considered if wear or failure is detected in tensioners or guides.


• Regular engine maintenance (oil changes, filter changes, and periodic inspections) is important to keep the chain and its components healthy.


• If you’re buying a used ES 350, a service history that includes chain/timing-system checks can be beneficial, but belt replacement is not a standard concern.

Bottom line: The absence of a timing belt in the ES 350 means there’s no routine belt-change schedule, but chain-related wear can still impact performance if components degrade over time.

Model-year coverage and engine details

Since its introduction in the United States, the ES 350 has relied on the 2GR-FE 3.5L V6 with a timing chain. This configuration has carried through multiple generations of the model, including updates and facelifts, ensuring the chain-driven design remains a constant feature. It’s worth noting that other ES variants, such as the ES 300h hybrid, use different engines with their own timing configurations; however, the ES 350 itself remains chain-driven across its typical US-market lineup.

What this means for maintenance and ownership

For owners, the lack of a timing belt translates to no belt-replacement interval to monitor. Instead, focus on overall engine care and the health of the timing-chain assembly. Listen for unusual chain noises at startup or idle, and adhere to the manufacturer’s service schedule to have tensioners and guides inspected during major service or high-mileage maintenance. If any noise or timing concerns arise, consult a Lexus-certified technician promptly.

Summary

The Lexus ES 350 does not have a timing belt; it uses a timing chain on the 2GR-FE V6. This means there is no regular belt-replacement interval, but it does require attention to chain-related components as the vehicle ages. Following the recommended maintenance schedule and staying alert to unusual engine sounds will help ensure the chain and its accessories stay in good condition across the model years.

How much does it cost to replace a timing chain on a Lexus ES350?

The average cost for a Lexus ES350 Timing Chain Tensioner Replacement is between $2,579 and $3,571. Labor costs are estimated between $2,123 and $3,116 while parts are typically priced around $456. This range does not include taxes and fees, and does not factor in your unique location.

When should the timing belt be changed on a Lexus ES 350?

However, as a general guideline, it's recommended to replace the timing belt every 60,000 to 100,000 miles or every 5 to 7 years, whichever comes first.

What year to stay away from Lexus ES 350?

You should avoid the 2007, 2008, 2011, 2013, 2014, and 2015 Lexus ES 350 models due to common issues like melting dashboards, engine/transmission problems, and other mechanical failures. While some later years also have specific reported problems, such as a hollow door design on some 2019 models that causes noise, the 2007-2015 period contains the most widely cited issues.
 
Years to avoid and common problems

• 2007–2009: Prone to oil leaks, engine issues like blown head gaskets, and AC problems from a defective evaporator core. The 2007 model is particularly known for its melting dashboard. Transmission problems like rough shifting and hesitations are also common. 
• 2011: Has a high number of complaints for various problems, including engine and transmission issues, as well as other mechanical failures. 
• 2013–2015: Reportedly have issues with exploding sunroofs, engine stalls when turning, and door lock malfunctions. Some of these years also saw problems with ventilated seats and powertrain fluid leaks. 
• 2019: Some owners reported that the doors feel hollow and let in a lot of road noise, a problem that was reportedly fixed around the 2020-2021 model years. 

Years that are generally considered more reliable

• 2012: Often mentioned as a good year to buy. 
• 2017–2019: Generally considered reliable with modern features. 
• 2020 and later: The years following the 2019 model year are generally considered more reliable, with some specific minor issues such as the hollow doors on 2019 models being addressed in later models. 

Does the Lexus ES 350 have a timing belt or chain?

The Lexus ES 350 has a timing chain, not a timing belt, and it is designed to last for the life of the engine. Unlike a timing belt that requires scheduled replacement, a timing chain does not have a set interval for replacement and is much more durable. You generally only need to replace the timing chain if there are specific problems like rattling noises from the engine, or after high mileage with signs of wear.
 
Timing chain vs. timing belt

• Timing chain: Made of metal, a timing chain is more durable and is expected to last for the life of the engine.
• Timing belt: Typically made of rubber, a timing belt needs to be replaced at specific mileage intervals (e.g., every 60,000 to 90,000 miles). 

When to check the timing chain

• No required service: There is no scheduled maintenance required for the timing chain unless you experience specific symptoms. 
• Symptoms of a problem: If you hear a rattling noise from the engine, especially at startup, or notice engine misfires, it could indicate a problem with the timing chain. 
• High mileage: Even with high mileage, replacement is typically unnecessary unless there are clear signs of wear, such as paint marks on the chain being gone.
