Re: 1941 180 coolant leak

My only 'thoughts'/advice would be to watch how much pressure you applied with the hand pump if you DO get one. I know my cooling system is a 'zero-pressure' circuit and depending on the condition of your rad (if the '41 is also 0-press.) it might not take much positive pressure to make it leak! Re, replacing the water pump, again, a fairly involved task, I would sure confirm the leak is coming from there before getting the sockets out or phoning your mechanic. As Dave (Owen_Dyneto) says, there is a weep hole in the back of the pump and coolant coming from there should be relatively easy to confirm. If you do end up removing the pump, it's always a good idea to pull the brass water distribution tube, but only possible if the rad is removed as well. Personally, I find working on these cars, leaning over the big fenders to be physically arduous and somewhat of a PITA. I built a fairly large plywood box about 10" off the ground, and standing on that helps. Although removing the front end clip is a task, it sure makes any of the aforementioned a WHOLE LOT easier! I've had mine off twice and the second time, it only took me a couple of hours to put it back. Just MY take though.... Chris.
