When should the timing belt be replaced on a Toyota Sequoia?

The timing belt on a Toyota Sequoia should typically be replaced every 60,000 to 90,000 miles, or every 5 to 7 years, whichever comes first. Replacing the timing belt at the recommended interval is crucial to prevent engine damage and ensure the smooth operation of your Sequoia.

What is a Timing Belt and Why is it Important?

The timing belt is a critical component in the engine of a Toyota Sequoia. It synchronizes the opening and closing of the engine's valves with the movement of the pistons, ensuring that the engine runs efficiently and without any misfiring or damage. If the timing belt breaks or becomes worn, it can cause the engine to stop running, potentially leading to costly repairs or even complete engine failure.

Recommended Timing Belt Replacement Interval

Toyota recommends replacing the timing belt on a Sequoia every 60,000 to 90,000 miles, or every 5 to 7 years, whichever comes first. This interval is based on the expected lifespan of the timing belt and the conditions under which the vehicle is typically operated.

Signs That the Timing Belt May Need Replacement

While the recommended replacement interval is a good guideline, there are also some signs that the timing belt may need to be replaced sooner, including:

• Unusual engine noises, such as a high-pitched whining or clicking sound


• Difficulty starting the engine or the engine stalling


• Reduced engine performance or fuel efficiency


• Visible cracks, fraying, or other signs of wear on the timing belt

If you notice any of these signs, it's important to have your Sequoia inspected by a qualified mechanic as soon as possible to determine if the timing belt needs to be replaced.

Timing Belt Replacement Cost

The cost to replace the timing belt on a Toyota Sequoia can vary depending on the specific model year and engine size, as well as the labor costs in your area. On average, you can expect to pay between $500 and $900 for a timing belt replacement, including parts and labor.

While the cost of a timing belt replacement may seem high, it's important to remember that the consequences of a broken timing belt can be much more expensive, potentially leading to engine damage or even complete engine failure. By replacing the timing belt at the recommended interval, you can help ensure the long-term reliability and performance of your Toyota Sequoia.

How long does a timing belt last on a Toyota Sequoia?

between 60,000 and 100,000 miles
If you do indeed have a timing belt in your Toyota, then it's imperative that you replace it at the proper interval. Typically, this occurs somewhere between 60,000 and 100,000 miles, so you'll want to either consult your Owner's Manual or one of our expert technicians if you're still unsure.

How much does it cost to replace a timing belt on a Toyota Sequoia?

The cost to replace a Toyota Sequoia timing belt typically ranges from $600 to over $1,400, depending on the specific model year and whether other parts like the water pump are replaced at the same time. Costs can vary based on factors like the service center (dealer vs. independent mechanic), your location, and the quality of the parts used. For a more specific estimate, you can check with local mechanics or use online cost calculators for your particular vehicle year.
 
Factors that influence the cost

• Service type: Dealerships may have higher labor rates but often use original equipment manufacturer (OEM) parts, while independent shops might be cheaper but use aftermarket parts. 
• Location: Costs are typically higher in metropolitan areas. 
• Labor time: Replacing the timing belt is labor-intensive, and costs can rise if additional components, such as the water pump, are replaced concurrently. It's often recommended to replace the water pump and other related parts at the same time. 
• Parts included: The final cost depends on whether you are just replacing the belt or a full kit that includes the tensioner, idler pulleys, and the water pump. 

How to get an accurate estimate

• Contact a local mechanic: Get quotes from both dealerships and independent shops to compare prices for your specific model and year. 
• Use online tools: Some websites allow you to get an estimate based on your vehicle's information. 

When to replace the timing belt

• Toyota recommends replacing the timing belt every 90,000–100,000 miles or every seven years, whichever comes first. 
• If your vehicle has over 90,000 miles and the belt has not been replaced, it is a good time to get it inspected. 
• A failing timing belt can cause significant engine damage if it snaps. 

What are the bad years to avoid Toyota Sequoia?

The Toyota Sequoia years to avoid are primarily the first generation models from 2001 to 2008 due to issues like frame rust, and potential problems with the engine, brakes, and steering. Within the second generation, 2008-2010 models also have specific concerns, such as secondary air injection system issues. 
First generation (2001-2007)

• 2001-2008: These years are frequently cited for being problematic due to a range of defects, including frame rust, steering issues, and engine and brake problems. 
• 2001-2007: Often mentioned for a higher risk of frame rust, especially if you live in an area that uses road salt. 
• 2002: This year stands out as having a high volume of severe complaints, notes CarBuzz. 
• 2003: Multiple recalls and issues with the Vehicle Stability Control system. 
• 2004: Subject to the Takata airbag recall. 
• 2006: Recalled 10 times by the NHTSA.

Second generation (2008-2017)

• 2008-2010: These models can have issues with the secondary air injection system, which can be expensive to fix. Early models also had a recall for accelerator pedal friction. 
• 2009: A recall for oil leaks that could lead to a sudden loss of power steering assistance. 
• 2017: Cited as a year to avoid by some sources. 

Do Toyota Sequoias have a timing belt or chain?

The Toyota Sequoia uses a timing belt for model years 2001-2009 and a timing chain for model years 2010 and newer. The engine type is a key determinant, as the 4.7L engine (2UZ-FE) uses a timing belt, while the 5.7L engine (3UR-FE) uses a timing chain.

Timing belt

• Applies to: 2001-2009 models 
• Maintenance: A timing belt has a recommended replacement interval, often around 90,000 miles, and failure can cause significant engine damage. 

Timing chain

• Applies to: 2010 and newer models 
• Maintenance: A timing chain is designed to last for the life of the engine and typically does not have a scheduled replacement interval. It is only replaced if it becomes damaged or worn out, which is rare.
