Finally! I can contribute something to the list!I have been reading a lot in the past few weeks. And am gaining a lot of knowledge. The Archives are really helpfull! My 83 vanagon is keeping me pretty busy. She has some serious cooling problems (which I knew before purshasing, and which is why I got her so cheap)  She tends ot want to get a little too hot, and I am slowly learning about the miles and miles of coolant hoses inside a vanagon! The challenge is, she does not have the original diesel motor anymore, she was converted to a fuel powered, with a Jetta engine, 91, 92 or 93, with a Rabbit head cover, and a carburator (!). I find it tricky, cause I can't really follow the Bentley, word for word. At first I though she was air-locked, but I think that I have all the air out of the cooling system now. She still runs hot...the cool coolant does not seem to reach the hot motor! Anyway, I though I'd share this: I installed a valve, sold by Kennedy Engeneering, were the air bleeder screw is. It is really easy to open and close the air bleeder hole on top of the rad. It is easyto open and close. (see pics) I am now in the process of making a reservoir with a long tube that I can attach to the expansion tank, to easilly fill the cooling system. It seems that if you pour in the rad fluid from a point higher than the radiator, you don't have to lift the front end. It seems to work. I'll let you know how it works out next week. I think that the overheting problem might be due to the fact that the Jetta water pump is not powerful enough to circulate the coolant in the bus. I found an original diesel vanagon pump and will try to instal it next week...  Marie Yukon Territory
