Subaru Variable Valve Timing Solenoid Replacement [5 Steps]

A Subaru variable valve timing solenoid is a vital component of the vehicle’s engine, and it needs to be replaced if it fails. This can be a difficult and expensive repair, but it is necessary in order to keep the engine running properly.

The Subaru variable valve timing solenoid is located in the engine, and it is responsible for controlling the timing of the engine’s valves. If this solenoid fails, the engine will not be able to properly control the timing of the valves, and this can lead to a number of problems.

The most common problem that occurs when the Subaru variable valve timing solenoid fails is that the engine will run rough. This is because the valves will not be opening and closing at the correct time, and this can cause the engine to misfire.

Another problem that can occur is that the engine will not be able to generate enough power. This is because the valves will not be opening at the correct time, and this can reduce the amount of air that is able to enter the engine.

If the Subaru variable valve timing solenoid fails, it is important to have it replaced as soon as possible. This is because the longer the problem is left, the more damage that can be caused to the engine.

Why Do You Need to Replace VVT?

If the Subaru variable valve timing solenoid fails, it is important to have it replaced for a number of reasons.

1. The first reason is that the engine will not be able to properly control the timing of the valves. This can lead to a number of problems, including the engine running rough, misfiring, and not being able to generate enough power.
2. The second reason is that the engine will start to wear out prematurely. This is because the valves will not be opening and closing at the correct time, and this can cause extra wear and tear on the engine.

The possibility of harm to other engine components is the third justification. This is due to the engine’s inability to appropriately regulate the frequency of the valves, and this can cause the timing belt to slip or the valves to become damaged.

How to Replace Subaru Variable Valve Timing

If the Subaru variable valve timing solenoid needs to be replaced, it is important to follow the steps below.

1. Remove the old solenoid: This is usually done by unplugging it from the engine and then removing it with a wrench.
2. Install the new solenoid: This is usually done by putting it in the same spot as the old one and then screwing it in place.
3. Reconnect the engine: This is usually done by plugging the new solenoid into the engine and then starting the engine.
4. Test the engine: This is usually done by driving the vehicle and making sure that the engine is running smoothly.
5. Take the vehicle to a mechanic: This is the best way to make sure that the engine is running properly and that the new solenoid is working correctly.

It is important to note that the steps above may vary depending on the vehicle. Therefore, it is always best to consult with a mechanic before attempting to replace the Subaru variable valve timing solenoid.

Cost of Replacement

The cost of replacing Subaru variable valve timing varies over the model and on the place you are servicing. But on average you have to pay around $120 for labor and $200 for parts. However, there are some factors that can increase or discourage the cost of replacement. Let’s have a look, 

Factors that Affect VVT replacement costs

The cost of replacing the Subaru variable valve timing solenoid can vary depending on a number of factors.

1. The first factor is the make and model of the vehicle. Some vehicles will have an easier time replacing the solenoid than others.
2. The second factor is the mechanic that is performing the replacement. Some mechanics will charge more than others for the same job.
3. The third factor is the location of the replacement. Some mechanics will charge more if the replacement is done in their shop rather than at the customer’s home.
4. The fourth factor is the warranty. Some mechanics will offer a warranty on the replacement, and this can save the customer money if there are any problems with the new solenoid.

Symptoms of a Bad or Failing Variable Valve Timing Solenoid

There are a few symptoms that can indicate that the Subaru variable valve timing solenoid is failing or has failed.

1. The first symptom is that the engine will run rough. This is because the valves will not be opening and closing at the correct time, and this can cause the engine to misfire.
2. The second symptom is that the engine will not be able to generate enough power. This is because the valves will not be opening at the correct time, and this can reduce the amount of air that is able to enter the engine.
3. The third symptom is that the engine will start to wear out prematurely. This is because the valves will not be opening and closing at the correct time, and this can cause extra wear and tear on the engine.
4. The fourth symptom is that it can cause damage to other parts of the engine. This is because the engine will not be able to properly control the timing of the valves, and this can cause the timing belt to slip or the valves to become damaged.

If any of these symptoms are present, it is important to have the Subaru variable valve timing solenoid replaced as soon as possible.
