How much does it cost to replace the timing chain on a 2007 Lexus LS 460?
Typically, replacing the timing chain on a 2007 Lexus LS 460 costs about $1,500 to $3,000 at an independent auto shop, with dealer pricing higher—roughly $2,500 to $4,000 or more depending on parts and labor.
Overview of the repair
The timing chain is a critical part of the LS 460's V8 engine. Replacement is a labor-intensive job that often involves replacing the chain, tensioners, and guides, and may extend to the water pump, seals, and other related components. Costs can vary widely depending on what else the shop notes during service.
Cost drivers
Several factors influence the final bill. Here is a breakdown of the main cost drivers when replacing a timing chain on this model.
Key cost drivers
- Labor time: Most LS 460 timing chain jobs fall in the 6–12 hour range, depending on access and whether related parts are replaced.
- Parts kit: A timing chain kit (chain, tensioners, guides, seals) typically costs several hundred dollars; OEM parts climb higher than aftermarket equivalents.
- Water pump and thermostat: Many shops replace the water pump concurrently, adding about $100–$350 for parts and labor.
- Cam phasers and oil pump drive: If wear is present, replacement can add several hundred dollars to the bill.
- Gaskets, seals, and fluids: Additional consumables and fluids add a modest, but real, cost.
- Diagnostics and shop rate: Regional labor-rate differences and diagnostic fees can shift the total by a few hundred dollars.
- Vehicle condition: If there is preexisting engine damage or related issues, the repair may balloon in price.
In general, the final price reflects how much of the engine is disassembled, what components are replaced, and where you go for service.
Typical pricing by shop type
Different kinds of shops price this job differently. The following ranges reflect common market conditions in the United States as of recent years.
- Independent or local repair shop: approximately $1,500–$3,000
- National chain repair shop: approximately $2,000–$3,500
- Lexus dealership: approximately $2,800–$4,500
- Mobile mechanic (if feasible for the job): approximately $1,800–$3,000
Note that these ranges are estimates and can vary by region, vehicle condition, and the shop's policies. Always request an itemized quote before authorizing work and ask whether the price includes a timing chain kit, labor, and any ancillary parts.
What to watch for and what to do next
If you suspect a timing chain issue—such as a rattle on startup or during idle, misalignment symptoms, or a check engine light indicating cam/crank position faults—address it promptly. Delaying replacement can lead to more extensive engine damage and higher costs.
Summary
For a 2007 Lexus LS 460, most owners should expect a total bill in the low-to-mid four figures, depending on shop, region, and whether additional components are replaced at the same time. The safe approach is to obtain multiple detailed estimates, verify what parts are included, and plan for potential extras like the water pump or cam phasers. Given the LS 460’s age, a proactive replacement is often prudent to protect the engine and maintain performance.
