My 93 Honda accord had radiator problems and leaks. I replaced the
thermostat and the radiator. it doesn't boilover anymore but I still can
hear that the water is boiling into the overflow container when I turn off
the car. when I turn off the car the fans stop... if I leave it for a few
minutes the fans turn back on. I have replaced the thermo with the
suggested value one. are the fans not turning on enough? is there an
electronic sensor that is turning on too high? shouldn't the water temp
stay below boil?

Thanks
