- Replacement is a labor-intensive job that requires removing the valve covers; it's best to replace all four solenoids at once.
- Due to the high labor cost, using high-quality OEM or premium aftermarket parts is recommended to avoid repeat repairs.
Is Your Taurus X VVT Solenoid Failing?
The VVT solenoids, also called VCT solenoids, are critical for engine performance. Because they rely on clean engine oil to work, the most common reason for failure is old or contaminated oil that clogs their internal passages and filter screens. When a solenoid gets stuck or fails, it can throw your engine's timing out of sync, leading to several noticeable problems.
A Note on Timing Chains and Trouble Codes
On the 3.5L V6 engine, certain trouble codes like P0016 and P0018 point to a disagreement between the crankshaft and camshaft positions. While this can be caused by a faulty VVT solenoid, it can also be a symptom of a more serious stretched timing chain, a known issue on these engines. 🎬 Learn why these 3.5L engines often suffer from jumped timing. If you have these codes, especially on a higher-mileage vehicle, it is critical to have a mechanic investigate the timing chain's condition 🎬 See how P0016 and P0018 codes relate to engine failure. before replacing only the solenoids.
Choosing the Right Aftermarket VVT Solenoid
Because replacing the VVT solenoids on the Taurus X is a labor-intensive job, the quality of the replacement part is very important. You don't want to do this job twice. Here’s an honest look at the brands available.
- Premium Brands (NGK, Standard Ignition): These brands have a strong reputation for quality and reliability, often meeting or exceeding OEM specifications. For a part that requires significant labor to replace, choosing a premium brand is a smart investment for long-term peace of mind.
- Standard Brands (Dorman, Gates, Beck Arnley, Cloyes): These brands offer a balance of value and quality. Dorman is well-known and often engineers its parts to fix common OEM flaws. However, for critical engine components like VVT solenoids, some professional mechanics and experienced owners prefer to use OEM or premium brands to ensure reliability.
- Economy Brands (Global Parts, Rostra Powertrain, Walker Products): These brands provide a cost-effective solution. They are a viable option if the budget is the primary concern, but may not offer the same longevity as more expensive alternatives.
Replace in Sets
Your Taurus X has four VVT solenoids. If one has failed from age or oil contamination, the others have been exposed to the same conditions and are likely near the end of their service life. Since the valve covers must be removed to access them, it is highly recommended to replace all four solenoids at the same time. Also, be sure to install new valve cover gaskets and VVT solenoid seals to prevent future oil leaks.

Frequently Asked Questions
Where are the VVT solenoids located on a 2008-2009 Ford Taurus X?
The VVT solenoids are located under the engine's valve covers. There are two on the front (Bank 2) and two on the rear (Bank 1, near the firewall). Accessing the rear solenoids is more difficult and may require removing the upper intake manifold.
🎬 Watch this step-by-step guide on replacing the solenoids.Can I replace just one bad VVT solenoid?
While you can replace just the one that has failed, it is strongly recommended to replace all four at once. The labor involved is significant, and the other solenoids are likely to fail soon after the first one. Replacing them all together saves you from paying for the same labor again in the near future.
Are there any recalls for this part?
No. While there have been recalls for the 2008-2009 Ford Taurus X for issues like airbags, there are no active recalls for the VVT solenoids or related engine timing components.
What is the best way to prevent VVT solenoid failure?
The best prevention is regular oil changes with high-quality, manufacturer-specified engine oil. Since dirty oil is the number one cause of failure, keeping your oil clean prevents the small passages in the solenoids from getting clogged.
