1995 Ford Mustang No Heat

I have one of these icebergs too. One reason for this no heat problem, and I assume you have no other mechanical issues, is the lack of circulation due to piss poor design. If you notice both heater lines have basically the same pressure available from the water pump. The solution is rather rigged up but will work. Take the top radiator hose, cut it and insert a pipe "T" of appropriate size and with the one side of the t bushed down to accept the return hose from the heater core. This will gurantee flow and I think will solve the heat issue on this series car.
