I just bought this Ford a month ago and repaired and replaced usual parts, but then all of a sudden have an indicator on for the water, and the reservoir water is boiling. I knew only a couple things could be the reason for the overheating, so I went and replaced the thermostat and water pump. There is no leaking anywhere or holes in any lines. I also made sure both fans kick on. Both radiators are brand new but it still boils out of the reservoir, not as bad now but continues to boil. Might be because of air in the radiator that has to be vacuumed out but shouldn't make it boil, should it? Please leave any comments of advice. I use it as a daily driver with my family, so please help if you can.
