At what mileage should timing belts be replaced on a Toyota Tundra?

Most Toyota Tundra engines use timing chains rather than belts, so there isn’t a mileage-based belt replacement schedule for the majority of modern Tundra models. If you own an older, belt-driven Tundra, replacement is typically around 90,000 miles, and many owners also replace the water pump at the same time. Always verify your exact engine and service schedule in your owner’s manual or with a Toyota dealer.

Belt-driven engines in older Tundras

Some early Tundra configurations used a timing belt. Here’s how to approach those engines and the maintenance they require.

• Replacement interval: commonly around 90,000 miles, but always confirm with the factory service schedule for your exact year and engine code.


• Concurrent maintenance: many technicians replace the water pump and belt-driven pulleys at the same time to prevent future labor costs and leaks.


• Signs of wear: look for cracks, fraying, oil contamination, or unusual belt-detection noises, all of which can indicate an impending failure.

For belt-driven Tundras, adhere to the official interval and use OEM parts to minimize the risk of belt failure and potential engine damage.

Chain-driven engines in modern Tundras

Since later model years, most Tundras rely on timing chains, which do not have a fixed mileage replacement interval and are built to last the life of the engine with proper maintenance.

• No fixed mileage interval: timing chains typically do not require regular replacement based on miles alone; replacement is done only if there is wear or a specific service need.


• Maintenance focus: regular oil changes with the correct viscosity and grade help preserve chain guides and tensioners, contributing to longevity.


• Symptoms of potential chain/tensioner problems: startup rattles, ticking or slapping noises, rough running, or misfires warrant prompt inspection by a technician.

For most owners of modern Tundra models, routine maintenance and timely oil changes are the best defense against timing-chain issues, with no routine mileage-based belt replacement required.

How to verify your truck’s timing system

To be certain whether your Tundra uses a belt or a chain, check the engine code printed on the under-hood sticker or in the service manual, and confirm via Toyota’s official documentation or a dealership. Your VIN can also be used to look up the original equipment and service intervals for your exact truck.

Bottom line

In practice, most Toyota Tundras do not have a periodic timing belt replacement schedule because they use timing chains. If you own an older belt-driven Tundra, plan belt replacement around the recommended interval (commonly about 90,000 miles) and consider replacing the water pump at the same time. For newer Tundras with chains, follow standard maintenance guidelines and address any unusual noises or timing-related symptoms promptly with a trusted technician.

Summary

The key takeaway is that timing belts are not a routine maintenance item for most Toyota Tundras built in the last two decades. Belt-driven engines, if present, typically require replacement around 90,000 miles with concurrent water-pump service. Modern Tundras largely use timing chains, which do not have a fixed mileage replacement interval and rely on regular maintenance and timely diagnostics instead.

Does the Toyota 5.7 L V8 have a timing belt or chain?

The Toyota 5.7L engine uses a timing chain, not a timing belt. Timing chains are designed to last the life of the engine, but they can wear over time, potentially leading to issues like noise or stretched chains.
 

• Durability: Timing chains are generally more durable than timing belts, which require scheduled replacement around every 60,000 to 100,000 miles. 
• Maintenance: While timing chains don't need routine replacement, they can develop problems like stretching or tensioner failure. 
• Warning signs: A stretched chain or failing tensioner might be indicated by engine noise, especially on a cold start, or loss of performance. 
• Engine design: The 5.7L is a V8 engine with multiple chains, which can contribute to a "ticky" sound that is normal for this engine. 
• Interference: The 5.7L engine is a non-interference engine, meaning that if the timing chain fails, the pistons and valves will not collide, which helps prevent severe engine damage. 

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

The cost to replace a Toyota Tundra's timing belt typically ranges from $800 to over $2,000, depending on the model year, engine, and shop. Newer models, especially those with V8-4.7L engines, can be more expensive, with dealer prices potentially reaching $2,500 or more. Labor is the largest cost due to extensive disassembly, so getting multiple quotes from both dealerships and independent mechanics is recommended.
 
Factors influencing cost

• Vehicle Year and Engine: Prices vary significantly between models and engine types. For example, 4.7L V8 engines have higher costs than V6 engines. 
• Location: Labor rates differ by region, with some areas, like California, showing higher quotes. 
• Shop Type:
  • Dealerships: Generally have higher labor rates but use manufacturer-recommended parts. 
  • Independent Shops: May have lower costs due to using aftermarket parts and different labor rates. 
• Included Parts: Many quotes include other components like the water pump, thermostat, and idler pulleys, which is standard and recommended practice. 
• Labor: The time it takes to complete the job is a significant portion of the total cost because many parts need to be disassembled to access the timing belt. 

Cost breakdowns

• Low End (Independent/DIY): If you're comfortable with DIY work, the parts kit might cost around $200. For a professional, independent shops might be in the $720 - $813 range for newer models, with some older models seeing estimates around $409 to $919. 
• Mid-Range (Independent/Shop): Quotes of $800 to $1,300 are frequently cited for a full timing belt and water pump replacement at an independent shop. 
• High End (Dealership): Dealership prices are often higher. For example, a 2007 4.7L V8 Tundra could have shop/dealer prices between $1,936 and $2,540. A 2006 AC model quote was $2,800 for the timing belt and water pump. 

Recommendations

• Get multiple quotes: Contact both dealerships and independent mechanics for written estimates before making a decision. 
• Inquire about parts: Ask if the quote includes the water pump, thermostat, and other associated components, as replacing them at the same time is standard practice. 
• Consider your vehicle's history: If the water pump or other parts have not been replaced, it is a good idea to do so during the timing belt service. 

How long does a Toyota Tundra timing belt last?

If you own a 2000 to 2004 V6 Tundra get ready for a replacement by 60k miles. For a 4.7 V8 engine made between 2000 and 2009, prepare to replace the belt when the mileage reaches 90k miles.

What year of Toyota Tundra to stay away from?

Years to be cautious with the Toyota Tundra include early second-generation models (2007–2013) due to potential head gasket issues and rust, initial third-generation models (2022–2024) for engine and transmission problems, and the 2017 for some recalls and a less refined ride compared to other years in its generation.
 
Second Generation (2007–2021)

• 2007–2013: These years can have head gasket issues that are manageable with regular coolant flushes. Rust on the frame is a concern, especially in rust-belt areas, and should be checked before purchase. 
• 2017: Some owners report issues, including a less refined ride, and a higher number of recalls compared to other years in this generation. 

Third Generation (2022–Present)

• 2022–2024: The initial model years for this generation have been linked to engine failures, mainly due to a manufacturing problem that led to a large recall. Issues with the new 10-speed transmission and problems with the new technology, like the infotainment system and power tailgates, have also been reported. 

What to consider before buying

• Check the recall history: Some issues, like head gasket problems on 2007–2013 models, can be mitigated by a previous engine replacement or repair. 
• Inspect the frame: For models from the second generation, carefully inspect the frame for rust, especially if you live in a region that uses road salt. 
• Consider a pre-purchase inspection: This is a good practice for any used vehicle, but especially for a model year you are wary of. 
• Look at model year reputation: While some years have specific issues, the overall reputation for the second generation is strong, especially the later years like 2019, 2020, and 2021, which have fewer reported problems.
