If your system is topped off with fluids and your water pump and radiator is good....its all in the thermostat. The wrong thermostat can cause this reaction. order a thermostat online specifically for your engine type, the ones at your local autoparts stores are not the correct ones...... i have experience the same thing your going thru and i finally got it.......my fan barely run high if at all and the engine temp remains cool.......remember also ..you have a bleeding process as well as filling up the expansion tank fluids... the fitting is on your top thermostat hose, a plastic, flat head fitting needs to be removed and filled with coolant first hand, then expansion tank there after......run it to full temp, let cool down and top off expasion tank if needed......
Try replacing the fan stat, usually on the rad
