92 honda civic lx overheating
My honda civic is overheating and water is bubbling into the overfill tank, and then leaking out. I already replaced radiator and thermostat and there seems to be no pressure from the lower radiator hose to the thermostat. The electric fan fails to come on when temperature is high. Replaced themosensor, and that didn't change fan. The fan runs when connected to a 12 volt power. Could it be fan relay, water pump. Or head gasket? There is a lot of steam pressure into the overflow tank when car overheats.
Thanks. elmer
