I paid $20 for an aftermarket valve from Amazon and it took me less than 5 minutes to change for my Chevy Equinox. I have noticed a huge difference in my cars Idling, power and gas mileage.

I just replaced my purge valve on my 2003 Buick PA... It tested good in regards to holding a vacuum, it was an aftermarket part. I was throwing an evap leak code, so I replaced with an ACDelco OEM valve, code gone. Spend the extra money and get the OEM part.

It also depends on the age of the vehicle also I have a 95 Plymouth Grand Voyager 3.3 6 cylinder right now my evap canister is disconnected I have no issues with fuel economy fuel vapors or fuel tank issues nothing in fact my vehicle runs even better and gotten better on gas mileage

Good video, easy to follow, but a lot of these symptoms are very vague and can be caused by a lot of other issues, as well.

A bad purge valve may cause bloating, upset stomach, and diarrhea…

Interesting, I’ll check it out

bro said all the things like 1000times😆

So on my van I never have problems with the smell of gas, but if the day goes up to about 92 degrees and when I run the back AC which puts a further drag on the engine, after about an hour it smells horrendous of vaporized fuel. My theory is that when the ambient temp in the engine rizes high enough the purge valve stays open allowing for the gas to leak out. THis condition is not often so I was wondering if I could override the value command from the ECU and make an external switch that will force it closed for a little while until I can get on a freeway to allow the engine to cool rather than the city stop and go. All parts have been replaced but still and issue. Any ideas around that duck tape idea?

evap codes can be many other things beside purge valve and can add up to alot of$. helpful video.✓

I had 1994 that I removed all the evap parts. Put a regular vent on the hose from the tank, and plugged all the vacuum lines. OBD 1 so it didn't check see if it was working. I think 1996 & up OBD II the ECU checks to see if it is working.

Can a bad charcoal cannister can also cause clogging for line to purge valve? I am having hard starts and stalling and mechanic said my purge value is working as it should but clogging of lines because of bad cannister most likely culprit. Would you agree?

Before trying all this try an alternative.......every time you park rev it up to 5000 for five seconds. It worked for me.

Labor cost of that amount no longer exist. 😂

Bad injectors and fuel pressure regulator do the same thing too

In my golf GTI 92 the valve not stay open or close, She ticking quickly, and work principaly at idle, its normal? I have disconnect the connector because the engine working a bit bad🤔

If its open there is no engine light.. is normal it tiks hard ad Idle?

No not really.. First, you show a carbureted engine and purge system. Not to many of those from the factory anymore. ALL the symptoms you mention MAY occur on a carb vehicle with an evap system but not on a fuel injected engine even though you try to relate it to a computer (EEC) controlled engine. The sole purpose of the "evaporative emissions system' is to prevent EVAPORATING fuel vapors from leaving the vehicle and entering the atmosphere. Hence the name. The vapors from the fuel tank are captured in the charcoal canister and then "purged" back into the engine to be burned at certain times during in the combustion process. Fuel tank venting is usually run through the charcoal canister so you might get a gas smell in your garage if the purge valve is inop and likely the computer would give a fault code. If the canister is damaged or plugged you may get fuel delivery problems from not allowing venting into the tank, but that's not the purge valve's issue. Fuel economy might suffer if a vacuum line in the evap system leaks allowing extra air in as would any uncontrolled vacuum leak. Again. not the purge valve. Even if the system does not use a canister to hold vapors, you make this sound way worse than it is, and you repeat yourself to make it sound that way.

Mine ,when truck running take the hose off want suck air at all even waiting 5 to 10 minutes running. Can you help me. Thanks.

My 2.4 engine is idling rough. The code says emission system small vacuum leak. When I completely cover the vacuum line going to the evap system, the rough idle does not go away. There is no change. Any ideas?

Can it vaise it to blow white smoke from the exhaust

Im glad my purge valve was only 25 dollars

Does this cause p0448?

Please tell us about anti-pollution fault ?

hi, i just saw the video, does the purge valve affect the RPM to go up to be high, or sometimes on the other hand the RPM goes down?.

question please answer. can a purge valve or evap issue cause back fire? my car started some tail pipe backfire after i had exhaust work done,, could that have loosened a hose or connecton with evap system. crazy question i know... but i need to figure this out. thx in advance also.

Will a faulty Canister Purge Valve cause the vehicle to go into limp mode?

"Purge valve" is used constantly in this video, but I think it is often referring to the canister vent solenoid and stated differently. There is a purge solenoid located near the engine top and near the throttle body, so I am a little confused as to what this person is always referring to. Most Vent Solenoids are located near the charcoal or vapor canister and yes, it does perform a purge function, however, most refer to it as a vent.

I have an issue with the car seeming to want to stall and but usually it keeps going. It actually did go out once with the lights coming on a couple of weeks ago. Three mechanics can't figure out what is wrong. No codes come up. We did have the canister and canister close valve replaced because we couldn't pump gas properly. So now we have this new issue and I'm not sure if it is connected to the same parts. Is the purge valve the same and canister close valve? This has been so stressful because I don't know what is going on. It seemed random but I am pretty sure now that it happens after I pump gas. Not right away but the next time I use the car. Any thoughts?

The getting fuel and hard start after is the surefire sign it's bad

will a stuck open purge valve cause hard to put gas in the tank like the pump keeps kicking off

Its vacuum not pressure right? Right!

You forgot, 'an incredible racket', you heard mine in the car. Was probably on its way out.

Can u clean a purge valve ?

I just changed one in my 2012 impala because it was hard to start

Every single thing said on this video is absolutely incorrect. Please do not mislead people on what the purge valve does before making videos like this. Just my humble opinion.

How dare you the estimate of labor price!!!! On your video, for people that doesn’t work on cars will thing is easy but most of the time isn’t easy to find out what’s going on with the evap codes

👌🏼👍🏽

What's the difference between a purge valve and a EGR valve???

I got my purge valve replaced today because the engine light came up, but I have noticed that my car is not going more than 3000 Rev, does anybody knows the cause of this? I have a 2022 ford mustang

All my lights are on

I’m confused on one thing, how can the purge valve expel all the fuel and air from the engine after being shut off, if the purge valve is AT the air INTAKE. Once the engine is off, there is nothing coming out from the exhaust because the intake and exhaust valves are alternatively closed, and the pistons are stopped in different position. So if the valve is defective and stock open, you’ll just have a hard time starting the car again, that’s all

Your voice sounds like Dean Cain !

When I'm at the gas pump it shuts off literally after every few seconds making it take 10 minutes to fill my tank ...can it be the purge valve?

Talk about driving your point home

Symptoms of a bad purge valve repeating the same thing over and over again.

Amazon 20 bucks

"A faulty purge valve can cause serious damage to your engine," said no engineer or mechanic ever. Come to think of it, almost no engineer would agree with much of anything in this video

Ozzammaz ZOOLOO VOODOO

you didn't tell nothing

I used to be a purge valve.

very confusing video. I really don't think you have a clue what you are talking about. (Clears out any leftover fuel from the engine?) a purge valve draws fuel vapors from the charcoal canister. Over heating? I'd like to see that. So stuck shut... won't push fuel vapors back into the engine instead they will run straight out of the exhaust blah blah..... get real, vacuum won't pull (air pressure pushing) fuel vapors from the tank, there's no vapors or fuel getting out the exhaust. I also doubt any shop would only charge $53 to change the purge valve, they would do diagnostics first even if you told them what you thought was wrong. "Oh my car is heating, steam everywhere, put on a purge valve", then you're mad because nothing was wrong with the valve, the thermostat was stuck.

easy by pass

Lol. It reduces vapor in the tank. Has nothing to do with vapor in the engine dude. Lol

junk

Respectfully : you are talking nonsense. "Clueless" doesn't even start to describe. Must've been some work in order to get close to everything wrong.

I don’t trust advice from someone who can’t spell hard
