HI Sorry if this has been asked before but I couldn't find it mentioned. I am trying to remove the radiator out of my 1991 HJZ80 1HZ Landy and I have come across whats looks like some sort of AC fitting attached to the front of the radiator. From what I can see, it needs to be removed to allow me to get the radiator out. However I cant see how it can be removed. There is a 10mm bolt attached to it that I started to loosen but heard what sounded like gas leaking out. Perhaps AC gas? I retightened that. Can anybody tell me how I get that fitting off the radiator? I have attached a photo looking down on this little critter. Many thanks
