How To Clean Vacuum Solenoid Block

Cleaning Vacuum Solenoid Block

How To Clean Vacuum Solenoid Block, isn’t it easy? Vacuum Solenoid Valves, often known as VSVs, are electrical components that allow vacuum from the intake manifold to pass to an actuator, such as an EGR valve or the EVAP system.

The solenoid regulates the vacuum flow via the ports to the EGR valve by controlling a rapid-deployment valve. Blow a strong stream of air through one of the hoses. Air should not be allowed to pass through. If neither air nor vacuum can flow through, the valve is appropriately closing.

What Exactly Is A Vacuum Solenoid Block 

Solenoid valves aid in the control of liquid or gas flow. The plunger of a typically closed solenoid valve is down when the valve is not energized, effectively shutting the valve and stopping liquid or gas flow. When the solenoid valve is generally closed, it is actuated or charged, and the magnetic field forces the plunger to raise.

A solenoid is an electromagnet made up of a coil of wire.

How Does Vacuum Solenoid Block Function

It also refers to any device that uses a solenoid to transfer electrical energy to mechanical energy. The gadget uses electric current to generate a magnetic field, then used to create linear motion.

How To Clean Vacuum Solenoid Block

Cleaning the vacuum solenoid valve can be done in two distinct methods, depending on your level of technical understanding. Because our foremost goal is to remove the dirt that prevents it from working correctly, most people should get the job done by just rinsing internal components without opening them.

You cannot do anything if the purge solenoid valve has a broken casing or a malfunctioning solenoid; you’ll have to replace it. However, if you examined the solenoid’s coil and found no damage to the housing, you can clean the valve, and it should start working again in most circumstances, saving you money.

Clean Your Vacuum Solenoid Valve Without Opening

The cleaning procedure without opening the valve is as follows:

Step #1

In both tubes of the purge solenoid valve, spray a generous amount of carb cleaner or MAF cleaner.

Step #2

Cover both ends with your fingers and gives it a good shake. Cover both ends of the cleaner and wait a few minutes for it to shed dirt.

Step #3

Allow the liquid to drain by uncovering the valve’s tubes. It should be gloomy, with dirt, charcoal, and rubbish were strewn about. Steps 1 and 2 should be done again as many times as necessary. It’s best if you keep doing it until the liquid has completely exited the valve.

If the liquid was clean the first time, likely, your purge solenoid valve isn’t clogging with dirt or debris, and dirt isn’t the issue. You may wish to continue doing this nonetheless; it will not hurt your valve.

Step #4

Clean the valve connector and the car switch with a contact cleaner.

Step #5

Allow time for everything to dry.

Opening And Deep Cleaning Your Purge Solenoid Valve

The purpose of purge solenoid valves is to prevent them from opening. You’ll be able to force the case open with a bit of flat blade screwdriver and something sharp, such as a small knife.

Step #1

The two parts of most purge solenoid valves, such as the Bosch type (found in many automobile models), are glued together. You need to try to remove as much adhesive as possible with the bit of a flat blade screwdriver.

Once you’ve noticed that you’ve removed a significant amount of glue, rip both ends of the casing apart firmly but cautiously.

Step #2

After dividing the two parts, you’ll have a small circular piece that looks like a cap. The opposite half houses all functional components, such as the solenoid and electrical connectors for the valve.

Take the valve body out of the casing.

Step #3

Examine the o-rings and rubber parts for wear. These components are not currently available for purchase separately. It would be fantastic if they can get it as a repair kit.

Step #4

Spray the inside of the solenoid as illustrated in the illustration:

To do the job, use a lot of Carb or MAF cleaner. It’s best to rub the orifices with a dry cloth for a thorough cleansing.

Step #5

Finally, put everything back together after it’s you clean and then seal it. Use Epoxy glue or RTV rubber to re-seal the casing.


A vacuum valve guides the movement of air or fluid to generate a vacuum. Gauges regulate Vacuum valves. It switches built into the machinery, which regulate the flow of air or pressure inside the valve and release it as needed. Protection Status
