Does the Lexus LX570 have a timing belt or chain?

The LX 570 uses a timing chain rather than a timing belt. In the vehicle’s 5.7-liter V8, the camshafts are driven by a metal timing chain, which means there is no regular timing belt replacement in standard maintenance. Chains are designed to last for the life of the engine, though wear on tensioners and guides can occur and may require service over time.

Engine timing configuration

Understanding whether a belt or chain powers the LX 570 helps buyers plan maintenance and budgeting. The LX 570 relies on a chain-driven timing system, a design choice that generally reduces the need for periodic belt changes. However, like all chain-driven engines, wear on ancillary components can develop and may necessitate service at high mileage or during major repairs.

Key implications for owners

Before listing the practical impact, here are the main points about a timing chain in the LX 570:

• No scheduled timing belt replacement interval in typical maintenance plans.


• Chain wear or tensioner/guide failure can cause noise or timing issues; these symptoms warrant prompt inspection.


• During timing-chain-related service, technicians may inspect or replace related components (such as the chain guides or tensioners), and occasionally other parts may be addressed in the same service visit.

Conclusion: The LX 570’s chain-based timing reduces routine belt maintenance, but owners should stay attentive to engine noise and follow service advisories for wear items.

Maintenance considerations

Practical tips and expectations for owners with a chain-driven V8 include:

• Maintain regular oil changes with the manufacturer-recommended grade and interval; oil quality and pressure affect chain tensioner performance.


• Be alert to unusual front-of-engine noises (rattling or slapping) which can indicate wear on tensioners or guides; have a dealer diagnose promptly.


• There is no traditional belt-change schedule; if a major engine service is performed, the shop may inspect or replace chain-related components as needed, potentially during the same operation.

Conclusion: Routine oil maintenance and timely diagnostics are the best ways to keep the LX 570’s timing chain reliable over its lifetime.

Summary

Bottom line: The Lexus LX 570 uses a timing chain rather than a timing belt. This design eliminates regular belt replacements and aligns with maintenance practices that emphasize oil health and periodic inspection of chain-related components. If you hear unusual engine noise or anticipate long-term high-mileage ownership, consult a Lexus technician for diagnosis and maintenance recommendations.

How much does it cost to replace a timing chain on a LX570?

The average cost for a 2021 Lexus LX570 Timing Chain Tensioner Replacement is between $1,861 and $2,579.

Does the Toyota 5.7 engine have a timing belt or chain?

The Toyota 5.7L engine uses a timing chain, not a belt. Timing chains are designed to last the life of the engine and do not require routine replacement like a timing belt. Replacement is only necessary if it becomes noisy or stretched, often due to wear on the tensioners, which can be caused by inconsistent oil changes, say Reddit users.

Timing chain vs. timing belt

• Timing chain:
  • Made of metal, like stainless steel, making it very durable and long-lasting. 
  • Doesn't need regular replacement under normal circumstances. 
  • May require replacement if it becomes noisy (e.g., a slapping sound) or if the tensioner fails, which is often a symptom of poor oil maintenance. 
• Timing belt:
  • Made of rubber, which can degrade and crack over time. 
  • Requires periodic replacement at a specific mileage or time interval to prevent failure. 
  • Failure can lead to severe engine damage.

What to do if you have an issue

• Listen for noise: A loud slapping sound, especially when the engine is cold, can indicate a worn timing chain or a failing tensioner. 
• Check your maintenance history: Regular oil changes are critical for the longevity of the timing chain and its components. 
• Consult a professional: If you suspect a problem, take the vehicle to a qualified mechanic or dealership for diagnosis. They can properly assess the issue and recommend the correct course of action. 

Does the LX570 have a timing belt or chain?

This Fits Your Lexus LX 570. Your engine's timing chain can stretch over time resulting in a check engine light that comes along with excessive noise from your engine's timing cover. If the chain has broken, which is a rare occurrence, the engine will not start.
