The truck starts up no problems idles perfect, I have changed the radiator, thermostat, water pump, hoses . While running or driving for like fifteen minutes the hoses get extremely hard almost to the point to where it wants to explode. The overfill fills up and when I release the pressure cap the hose pressure goes down to normal then the pressure builds up again as I keep it running. I am out of ideas. Please help!
