Where is the fuel tank purge valve located on an 08 Astra?

Re: Emissions
 

The tank purge valve, I've no idea. Only know where the fuel rail purge is, but I'm guessing that won't help!

I even had a look on the UK forums, which is usually a goldmine of info, and nothing...

Re: Emissions
 

Are you looking for the evaporative emissions canister vent?

Re: Emissions
 

I think someone asked this once before. The charcoal cannister is located inside the right fender near the passenger door hinges (you'll need to remove the black plastic fender liner to see it). From there, the hoses run directly into the engine compartment near the right strut tower (there should be two quick-release connectors), and to the purge valve near the valve/tappet cover.

Re: Emissions
 

Thanks! The rear of the engine compartment is where I thought the purge valve was. Then I ordered the part and the description for the part says Fuel tank purge valve. Good I didn't want to drop the fuel tank! Thanks Again

Re: Emissions
 

Hello everyone! I was hoping somebody can confirm for me that the EVAP purge valve is indeed on the passenger side. Is it in front of the tire or behind it? This is in regards to a 2008 Saturn Astra. Thank you very much for any information you can provide me, I really appreciate it.

Re: Emissions
 

Well, thanks to the above poster I just wasted my time removing the plastic wheel well to locate the EVAP purge valve on a 2008 Astra. When in fact it is located next to the gas tank driver side rear. For those of you looking to change one, I did't even need to jack the car up, or use any tools to replace it. It took about two minutes.

Re: Emissions
 

Astra19, can you describe in more detail how you changed the EVAP valve? I have had my check engine lite on for a month, the dealership tried selling me off on the gas cap being the issue, but didn't solve the problem. I'm bringing it in tomorrow to get looked at again, but I'd rather take the reading from the diagnostic they run and fix it myself. The issue is every time I fill up on gas the Astra takes about 2-4 tries to turn over. This is the only time it does this, no rough idles, no shaky accelerations, just fill ups. I'm pretty sure it's the EVAP valve, but I'm sure someone on here might have a better idea.

Derek.erickson2,
The part you need to solve your problem is here. [URL="http://www.amazon.com/ACDelco-55562350-ACDELCO-VALVE-CNSTR/dp/B005OVJCYUhttp://"]http://www.amazon.com/ACDelco-55562350-ACDELCO-VALVE-CNSTR/dp/B005OVJCYU[/URL]

There is a cryptic picture of it in Post#3. It is located at the intake manifold in the engine bay.

When this valve fails to close and you fill the tank, fuel is forced into the intake manifold. This floods the engine and makes it hard to start. I replaced this about a year ago due to the same symptoms.

bdshaffer,

That sounds like the part I am looking for. I had the diagnostic run again today and it came back with a p0496, the GM dealership where I am stationed, Fort Polk, LA, wanted to charge me to do their own diagnostic, some other emission tests, and labor. Told them to screw off and simply called my relative that works at a dealership in Wisconsin. Read her the code and gave her the symptoms. Called back a few hours later and talked with a service rep who said that its a simple vent solenoid that needs to be replaced: GM part 25932570, runs at $15 at gmpartsdirect.com Now I am looking for someone to give me some advice. Should I go with bdshaffer and buy the ACDelco 55562350 ACDELCO VALVE,EVAP EMIS CNSTR PURGE SOL(W/BRKT) or better off with the one from gmpartsdirect?

Re: Emissions
 

Those are two different parts. The 555562350 is the one I think you should replace. It is under the hood.

The 25932570 is the canister vent solenoid located under the car in front of the fuel tank.

Re: Emissions
 

I figured they were, but I wasn't quite sure if ACDelco would have the same or different part numbers. I definitely thinking the part 555562350 sounds to fit the cause, but I think I'll end up purchasing both just because they aren't expensive and will probably help the issue. Thanks a ton for the help, it is much appreciated.

Re: Emissions
 

So I received the part today, now the question is how do I remove the elbow connector on the left side of the valve? I didn't want to put to much effort into ripping it off and damaging the part so I left it until I could get better guidance. The images uploaded are the current EVAP valve on the Astra, where the left side has the connecting elbow, and the other picture is of the new EVAP situated in the same position that it will be in once installed. Anyone help?

Re: Emissions
 

Pull and twist.

Re: Emissions
 

I'm seeing a code PO496 and stumbled on this thread, and am wondering how it ended up.

Derek - did replacing part number 555562350 "Evap valve" make the code go away?

Thanks, Newell

Re: Emissions
 

I never did hear from Derek, but I bought the part anyways. Two results:[LIST][*]The part number is 55562350, not 555562350 (too many 5's). I was unable to buy it from any of the local parts stores, so I bought it online. After shipping, it was nearly $100.[*]The replacement part did in fact make my code PO496 go away[/LIST]

Re: Emissions
 

Part number 55562350 is available on Amazon for $72.64 at the moment in case anyone is interested!

Re: Emissions
 

I stumbled on this thread also, having same issue, my 2008 Saturn Astra XE having real hard start issues, only after filling up the fuel tank, I ordered, the ACDelco 55562350 form Amazon last night, hoping it fixes the issue, Just to clarify..I am planning on digging in tomorrow, this part is located in the engine bay, by the intake manifold, correct?

Re: Emissions
 

Hello, I am having the flooded engine issue so I plan on replacing the purge valve to fix the problem.

I was wondering if anyone who also had this problem noticed any other engine codes pop up that this may have corrected for them? This code being the P0496.

I have been plagued with emissions problems....go figure, the parts the manufacturer is FORCED to install on all vehicles are made like subpar garbage and are more often than not the cause of most automotive problems these days...really annoys me as I am too broke to fix things as they fail and you know what happens when you don't repair an emission problem ASAP...the entire system implodes and takes everything else with it.

Ive already replaced the MAF, the O2 sensors and the entire flippin exhaust manifold because the catalytic converter colapsed on itself in the exhaust exit and choked my car to death. Thanks to GMs brilliant design, I couldn't eliminate the cat altogether, I had to replace it. Now I am afraid that this replacement cat will also fall apart due to whatever the problem is now.

Anyway sorry for the rant but I hate emissions systems hahaha. It would probably be cheaper if we just paid the government an emissions tax to help them pay for R&D and environmental repairs than to fit cars with emissions systems.

With the P0496 purge code I have:
-P0136 O2 sensor circuit malfunction bank1 sensor2
-P0141 O2 sensor heater circuit malfunction bank1 sensor2
-P2A01 O2 sensor circuit range/performance bank1 sensor2
-P2096 post cat fuel trim system too lean bank1
-P0101 MAF circuit range/performance problem

Anyone else have this wonderfully fantastic and hopelessly vague spread of codes along with the purge valve code? Im hoping the purge valve is causing all of this...though it may be too late, it may have already fouled out my cat and my O2 sensors.

Re: Emissions
 

My Astra just threw P0496 this morning in traffic. I filled up with gas last night about 30 miles ago. No issues in regards to how the engine runs. I deleted the code with my reader and will report back if it returns. 127k miles.
