Thanks to both Kwilford and Webster I was able to figure out the coolant hose connections, however the previous owner had an in-line water heater that was hooked up some how over the passenger wheel. I say this because the car was in pieces when I got it. The problem is that there is an extra coolant line coming from the bottom passenger side of the engine just behind the oil pressure guage (presumably the line went to the long gone in-line heater) . Is this line connected to the rear drain plug? What should I do, just plug the hose or take it back to the block and shut it off there. Any suggestions. If I plug it at the block, where do I get the plug? and how do I get at it?
Another question: There is a black wire with an "O" ring connector on the top side of the heater blower, where or what does it connect to?
