I have a honda jazz 2005 1.3 idsi car Over heated a couple of times cus of a leak, and fan not working. I fixed fan i deleted the thermostat. Was working fine until it started heating again. Cars heating when fan works coolant is full. Mechanic states its the head. But no sign of a bad head like no milky like coolant in radiator, no smoke, engine oil is fine. Could it be the water pump, again no sign of water pump being faulty like no leak no sound. Mechanic states its the head what should i do? Can a bad head lead to heating without any symptoms
