I have a 2008 Hyundai Santa Fe GLS, and my check engine light came on because of a failure to purge code. I took off the canister purge valve and immediately thought I had misidentified it, because there was coolant fluid in the line.

I went back to the diagrams and verified I had the correct part. I put a 9-volt battery on the leads, and sure enough, it would not open.

I have the new valve, which works fine with the 9-volt test, but I'm a little concerned I have a larger problem...

Why would there be coolant fluid there? It's not even close to any of the manifold sections through which the coolant runs. Plus, it's on the canister side, not the release side. Could it just be bad gas that looks like coolant fluid (I didn't taste test it, but it is green :)?

  • Bad gas wouldn't be green... Is the car's coolant green? I've seen a lot of pink lately, so I'd at least check the color. If you still have some, can you at least smell it? Of course I guess it might have absorbed some gas smell... – JPhi1618 Mar 29 '16 at 20:30

    May be a leak in the throttle body. Though it's odd that the purge valve would have any fluid in it. Can you take a picture of the line and the fluid? Maybe at some point someone attached a coolant line to the purge valve for whatever reason. – Ben Mar 29 '16 at 21:05
  • Yes, the car's coolant is green. I did smell it, and it smelled like coolant. it even separated from the gas when it hit the ground, and it was clearly neon green – Dexter Mar 29 '16 at 21:07
  • @Ben I still haven't figured out how the coolant got there, and it fell out when I tried to take a picture, but replacing the throttle body has fixed the problem. I don't even see where a coolant line attaches there, but I haven't seen any since I replaced it. – Dexter Apr 3 '16 at 0:59
  • @Dexter That's great, glad it's resolved. Perhaps you can answer your question and award it to yourself? Thanks! – DucatiKiller Apr 5 '16 at 1:37
