What is a Variable Valve Timing Solenoid and Why Should I Clean It?


An electromagnet is known as a solenoid, and it is used in an internal combustion engine to control the opening and closing of a valve. It is put to work in a variety of different capacities, such as regulating fuel pressure and managing the flow of air. It is essential to maintain this component in a clean state in order to ensure that your engine continues to operate efficiently. If debris gets stuck in the solenoid, it can lead to a variety of problems, including poor engine performance and low fuel economy. These problems can be caused by the solenoid being clogged. For this reason, keeping this component clean is really necessary if you want it to continue to perform as intended. It is advised that the solenoid be cleaned at least once each year, or anytime there is a discernible decrease in the performance of the engine. It is essential to take into consideration the fact that there are two distinct types of solenoids, namely VVT and EGR. Variable valve timing, also known by its acronym VVT, is a characteristic that is frequently seen on more recent vehicles. Exhaust gas recirculation, sometimes known as EGR, is a characteristic that is typically present in more fundamental or older models of automobiles. There is a solenoid for the variable valve timing on every vehicle, however not every car has an EGR solenoid. Before attempting to clean the solenoid in your vehicle, you need to first become familiar with the type of solenoid that is installed in the vehicle.


What Tools Do I Need to Clean a Variable Valve Timing Solenoid?

You are going to want some fundamental cleaning products in order to properly clean a solenoid. We advise that you get a vacuum for the engine compartment as well as an EGR cleaner and a brush to clean the solenoid. You will, of course, also require a few more fundamental tools in addition to these. We suggest that you use some gloves, a wrench, and a screwdriver while you work on this. You should begin the process of cleaning the engine by removing the solenoid from the engine, and these items will be of assistance to you in doing so. The chart that we’ve provided below gives you some further information on the resources that you’ll need to complete this task. When you go shopping for the supplies that you’ll need to clean the solenoid, you can use this as a guide to help you choose the right items.

How to Prepare the Vehicle for Cleaning the Solenoid

Before you start cleaning the solenoid, you need to make sure that the vehicle is in the proper operating condition. To begin, you need to park the vehicle outside on a surface that is level, such as a driveway. If you park it inside, there is a possibility that dirt and dust will get into the engine, which could result in damage to the vehicle. Your next step is to examine the condition of the car’s fluids and ensure that they are all at the appropriate levels. This includes the engine oil, the transmission fluid, and the coolant. Before you clean the solenoid, you need to address the problem if you find that any of these values are below their normal thresholds. In addition to this, you need to check to see that the battery in the vehicle has been fully charged. In the event that it is not, you run the danger of causing damage to the solenoid as well as to other components of the engine.

How to Clean a Variable Valve Timing Solenoid

You are now able to start the process of cleaning the solenoid and the car because you have already prepped them. In order to get the engine started, you will need to take the solenoid out of the engine. Depending on where it is situated, this may present a number of difficulties. As a result of this, we strongly advise that you wear gloves and get a few tools ready in advance. After you get the solenoid removed from its housing, you can then start cleaning it. To begin, get a brush and move any debris that is loose from the outside of the unit using it. The next step is to take your EGR cleaner and spray it on the interior of the solenoid, then scrub it. Now that you’ve finished cleaning the engine compartment, you may finish reinstalling the solenoid. When you are finished, make sure to wipe off the solenoid in order to remove any residue that may have been left behind. This will prevent debris such as dirt and dust from getting into the engine.

Tips for a Successful Cleaning

Make sure that the vehicle is positioned on a level surface before you start cleaning the solenoid. This will make your job much easier. In addition to that, make sure that you check the levels of the battery and the fluids in the engine. Before you start cleaning, make sure that they have been refilled if they need to be. After you have finished cleaning the solenoid, you should wipe it down to remove any dirt or debris that may still be on it. When you have finished cleaning the solenoid, you should observe an improvement in the operation of the car.

What to Do After Cleaning the Solenoid

After the solenoid has been meticulously cleaned, it is essential to do routine maintenance on it in order to ensure that it continues to function for the longest period of time feasible. Always remember to keep the engine oil clean so that the solenoid will continue to function as it should in the long run. A solenoid that is well-lubricated and able to perform its intended purpose requires oil that has been thoroughly cleaned. Altering the air filter in your engine on a regular basis will also help you maintain a clean solenoid. It is possible for a dirty air filter to become clogged with dirt and dust, which will restrict the amount of airflow to the solenoid, ultimately leading to its failure. You can avoid the part from failing prematurely and ensure that your vehicle will continue to operate smoothly for a significant amount of time and distance if you keep the solenoid and the engine oil clean.

Cleaning your VVT with Kreen

The use of variable valve timing, abbreviated as VVT, has become standard in virtually all designs of contemporary engines. The operation of the VVT is dependent on the hydraulic oil pressure that is generated through a lengthy and meandering path of incredibly small oil passageways known as “vanes.” Following its passage through a very fine screen, the oil destined for the VVT system is subsequently delivered to the Oil Control Valve (OCV). The oil is able to continue on its journey to the VVT controller/actuator thanks to the oil control valve (OCV). The oil pressure rotates the controller, which either moves the intake cams or the exhaust cams forward or backward. The ECU evaluates the throttle position, engine rotations, engine coolant temperature, and intake air volume before making a decision about how much the OCV should be opened or closed. The oil pressure is adjusted, and this causes the actuator to take on a variety of configurations.

Vulnerable deposits, a dirty VVT system can have an effect on the performance of the engine, the mileage that it gets on the gas tank, and it can give you ticks. This is especially obvious right after the computer has been turned on. A clean system can be maintained to a large extent by doing routine oil changes on schedule and making use of quality synthetic oils. However, there are circumstances in which manual intervention is required. Try using an oil additive made by Kano Labs called Kreen before you start taking the VVT system apart piece by piece. It is a cleaning that is used in industrial settings and is not available for purchase in retail stores since improper handling might cause it to be toxic. The amount of hardened carbon deposits and varnish that can be removed by using Kreen is significantly increased. Although it is not a quick flush, Kreen can be put to the oil and the vehicle can still be driven while the cleaning procedure is carried out.

The way that I use Kreen is by adding three ounces to each quart of oil, and then changing the oil every one thousand miles. If you replace your oil every 5,000 miles, for instance, you should add Kreen to your engine every 4,000 miles. In addition, I recommend utilizing Kreen either outside or in a location that has adequate ventilation, and I also recommend transferring Kreen from its metal container into a glass bottle.

In addition to that, Kreen can be used to soak pistons, and it can also be mixed with gas to clean fuel systems. If you use this product every 30,000 miles, you will have a VVT system that is free of problems and quiet.
