I just bought a used 90 4runner. Was running great a about 3days. It began to over heat. I've flushed the radiator and changed the thermastate and a couple of hoses. The fan is working find. The temp goes beyond the middle mark on temp gauge after about 45mins of driving. Temp wont change from just sitting an running. Had a coolant diag. Test performed they said some of the hoses were lose
so they "tightend" them same problem. Any suggestions please
