Hey guys I got a 94 3.8 liter stang and wanted to ask you guys about this because you usually know the answers. When removing the water pump, there is a black pipe on top that I believe is for the heater core. It has a bolt in it but I remember when I swapped my head gaskets I couldnt get the pipe out of the water pump. Well now I need to swap water pumps and the pipe needs to come out. Do any of you guys know how to get that pipe out of the water pump, unless mine is just stuck? Thanks for the help
