How much does it cost to replace cam phasers?
In most cars, replacing a cam phaser typically costs between $600 and $1,500 for a single unit, and about $1,200 to $3,000 if both phasers in a dual-VVT engine must be replaced, depending on the vehicle, the parts chosen, and local labor rates.
What cam phasers do and why they fail
Cam phasers are part of a modern engine's variable valve timing system. They adjust the timing of the camshaft to optimize power and efficiency. Phasers can wear or stick due to oil issues, sludge, or worn solenoids, leading to symptoms such as rough idling, reduced power, ticking noises, or a check-engine light. Replacing them often involves accessing and aligning the timing system, and may require a timing chain kit, new gaskets, and related components.
Cost drivers
Several factors determine the final bill for cam phaser replacement. The list below explains the main influences.
- Engine design and the number of phasers involved (single vs. dual phasers).
- Whether a timing chain kit, tensioners, guides, and gasket kit are required.
- Labor time and regional labor rates (dealership vs. independent shop).
- The choice between OEM and aftermarket parts, and availability of core exchanges.
- Potential additional repairs if mis-timing has caused damage to pistons or valves.
Costs vary with these factors; a precise quote depends on your specific vehicle and shop.
Pricing ranges by setup
The ranges below reflect typical costs you might see for common vehicles, including parts and labor. They are intended as a guide and can shift with market prices and vehicle complexity.
- Single cam phaser replacement: 600 – 1,500
- Dual cam phasers replacement: 1,200 – 2,800
- High-complexity engines or dealer-level work: 2,800 – 4,000+
Note that these figures include parts and labor but exclude taxes, disposal fees, and any diagnostic charges. Always obtain a written, itemized estimate before work begins.
Getting an accurate quote
To obtain an exact price for your vehicle, shops typically need details about your car and its symptoms. The steps below help ensure you receive a clear, apples-to-apples estimate.
- Provide the vehicle identification number (VIN), engine code, and suspected issue description (symptoms).
- Ask for an itemized quote listing parts (phaser kit, timing chain kit, gaskets, oil, etc.) and labor hours.
- Confirm whether the timing chain kit is included or required and whether any additional repairs are anticipated.
- Check warranty coverage and whether remanufactured or aftermarket parts are eligible.
Taking these steps can help you compare quotes effectively and avoid surprise charges.
Ways to save money
Consumers can sometimes reduce costs without compromising safety by exploring these options.
- Shop around and request quotes from multiple shops; ask for an apples-to-apples comparison.
- Ask about remanufactured or aftermarket cam phasers and whether they carry a warranty.
- Ensure the engine oil is clean and changed on schedule to minimize future phaser wear.
- If diagnosed early, consider replacing only the failing component (solenoid or phaser) if appropriate, rather than a full timing kit.
Even with savings, cam phaser replacement is a major repair that should be performed by an experienced mechanic to avoid timing issues that could damage the engine.
Summary
Cam phaser replacement costs vary widely but generally fall into predictable ranges based on how many phasers are involved, the engine design, and the shop’s labor rate. A single phaser commonly runs about $600–$1,500, while dual phasers can reach roughly $1,200–$2,800, with higher-end cases exceeding that. For the most accurate estimate, obtain an itemized quote from a trusted shop after they inspect the vehicle and confirm the scope of work required. Regular maintenance and proactive diagnostics help prevent unexpected timing-system failures.
