Cleaning the purge solenoid valve can be done in two distinct methods, depending on your level of technical understanding. When the major goal is to remove the dirt, most people should be able to get the job done by just cleaning internal parts without opening them. However, for deep cleansing, you need to open the valve.
How to Clean Purge Solenoid Valve
The purge solenoid valve is a component of the Evaporative Emission Control system of a vehicle. Its primary function is to keep fuel vapor from exiting the fuel tank.
When a contemporary car’s engine warms up, the valve gradually opens. As a result, some gases can go from the charcoal canister to the engine, where they are burned. Various sensors, on the other hand, keep track of the flow.
There isn’t much you can do if the purge solenoid valve has a broken casing or a malfunctioning solenoid; you’ll have to replace it. However, if you verified the solenoid’s coil and found no damage to the housing, you can clean the valve. In many situations, it will solve the problem.
Cleaning the Purge Valve Without Opening It
if you don’t have enough technical knowledge, this process is for you. It is a simple process of cleaning a solenoid purge valve which solves the issues mostly. Here are the steps of it.
Step 1: Spray MAF Cleaner
Begin by squirting MAF or carb cleaning into both purge solenoid valve tubes.
Step 2: Shake and Give Time
Seal both ends with your fingers and give it a good shake. Cover both ends of the cleaner and wait a few minutes for it to shed dirt.
Step 3: Diminish the liquid
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 repeated as needed. 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 clogged 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: Spray Contact Cleaner
Clean the valve’s connector and the automobile switch with a contact cleaner. Wait till everything is dried.
Deep Cleaning the Purge Valve by Opening It
Purge solenoid valves are not made to be opened. You’ll be able to force the case open with a little flat blade screwdriver and something sharp, such as a small knife. Here are the steps of deep cleansing the solenoid valve.
Step 1: Remove Glue
The two parts of most purge solenoid valves, such as the Bosch type which is used in many car models are glued together. What you need to do is try to eliminate as much adhesive as possible with the little 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: Detach valve
After you’ve divided the two parts, you’ll have a small circular piece that looks like a cap. The opposite half houses all of the operating parts, such as the solenoid and electrical connectors for the valve. You can now take the valve body out of the casing.
Step 3: Replace any parts that need to be replaced.
Examine the o-rings and rubber parts for wear. These components are not currently available for purchase separately. It would be fantastic if they could be purchased as a repair kit. You won’t be able to do much about it.
If they’re still in one piece, you can try lubricating them with silicone grease. The upper rubbers and the top o-ring are the most difficult to work with. The bottom o-ring is also crucial for good sealing. If you consider that it needs to be replaced, this one is easy to locate.
The electrical element of the valve may be working properly, but it may be leaking due to a faulty o-ring. Thus, when reassembling the valve, it’s critical to seal everything back up.
Step 4: Spray with MAF Cleaner
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: Reassemble the piece.
It’s time to place everything back again after it’s been cleaned and sealed. Use Epoxy glue or RTV rubber to re-seal the casing. It’s important to remember that once you’ve shut your purge solenoid valve with these goods, reopening it can be difficult. Before gluing the two sections back together, double-check that everything is in place.
While the glue is drying, apply hard pressure. It’s best to clamp the reassembled valve in a vise during the glue or RTV dries. When it’s safe to ignore your fixed purge solenoid valve from the vise, read the instructions that came with your glue.
Bad purge valves can result in severe damage to the EVAP system and other components of the vehicle. Though you can drive with it, it’s always recommended to check out. Cleaning the solenoid purge valve occasionally without opening it can boost your engine’s performance. However, to deep clean, you must have the needed technical knowledge.
