My Impala, is running hot. Changed the themostat, water pump, radiator and cap, head gasket. The car starts out running fine and I have heat. Car starts over heating, heat quits and electric fans come on and starts blowing coolant out. Do you have any ideas on what I need to do now. I am reallly stumpped. I feel the fans wait to long to come on. Was told my new thermostat is set for 195, and that was the coolest they could put in it.
