Do the girls all return around the same time? Is it a seasonal thing? lol Like animal migration...
Check to see if your leaking any fluid (coolant/water). If you have a fast leak that would explain the overheat after adding water. Could be a problem with the thermostat. Theres ways to check, id google it cus i dont know it off the top of my head. The fan not working would cause overheating noticeable during the times when you stop or slow down like in city traffic or bad fwy traffic. While traveling at speed with air flow going through the radiator, you wont notice overheating because the air is flowing.
