I have a 94 F-150 with a 5.0 and I'm having an overheating problem. I was driving along and looked behind me to see enough smoke to blind the cars behind me. So I tried changing the thermostat and flushing the radiator. It seemed fine a few days, then the problem occurred again. Only this time my bottom radiator hose busted. I got that changed thinking it may have been old and closed in on itself. Once again it drove fine a few days and now the same problem. Any ideas?
