The coolant is not coming in from the bottom. It is coming in from the top per several including list vendors who knew what I was doing. That's how it's done to convert over to the new style tank. Otherwise the hoses available these days don't stand a chance of fitting. I can see that that is a change that was made from before and now I'm having a problem. I don'tunderstand how it could be a problem, but it certainly is coincidental with the problem I'm having. So I'm interested in knowing more.
