CHEVROLET IMPALA COOLANT PROBLEM

2002 Chevrolet Impala • 187,000 miles

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.

Maybe try replacing the temperature sensor. Or maybe you have a cracked cylinder or block
