More than likely, you are releasing the R-134A refrigerant from your AC system. Again, I can't say for certain since there's no car info to tell which engine you have and the pic is so close to the valve that I can't tell if it could be the high or the low side. Plus you say that it is running to your radiator? (why would your cooling system have that much air under should only contain coolant)

You'll definitely know this summer if you released your refrigerant if your AC will only pump out warm air.
Thanks, QSilver7!

You are right, that was the A/C refrigerant valve. I don't think I lost too much R-134A, but I will probably top it off in the summer. Do you know if that is the high pressure valve? There is another valve near the windshield washer tank close to passenger firewall. I guess that one is the low pressure one. Is that correct?

I have updated my signature with my SAV's specifications. Thanks for pointing that out!
