Are you sure those valves you saw were not on the air conditioner lines? If so those are not what I am talking about.
I've got an 11 X and I'm pretty sure they are the same, I went out and took a short look and did not see a bleed valve. You could unhook a water line up high and bleed it that way, however I'm not sure of your mechanical abalities/what you are confortable doing. I guess if it's not overheating I'd just take it to a shop and let them purge the air from the system. If I was there, I could do it easily for you, but, I'm not and I can't do it via e-mail. lol.
