So have a 50 Chevy on s10 frame. Retained the 4.3 motor. It's sat for about a week and drove it out of garage. See some water/antifreeze leaking. Pull back in. Fill the radiator with truck off and I can hear some of it dripping onto floor. Keep filling and start it. Starts gushing out. I'm thinking freeze plug or water pump. Any way to tell ehich to lean towards or best way to trace it out? Heres some videos...
