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

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...

Are you looking for the evaporative emissions canister vent?

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.

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

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.

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.

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. http://www.amazon.com/ACDelco-55562350-ACDELCO-VALVE-CNSTR/dp/B005OVJCYU

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.

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?

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

I never did hear from Derek, but I bought the part anyways. Two results:
  • 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
