Medical professionals use a lot of lingo that the lay person doesn't understand and the doctor or midwife doesn't think twice about it so ask if you don't understand. a long cervix is quite normal.
The fan or fans should run when the coolant temperature in the radiator is above the temperature of the thermostat for your vehicle. Probably around 190 degrees. The answer should be in your operators manual as to what temperature a fan or fans should come on. Sometimes just one fan will operate if the water temperature dictates.
Re: cooling fans come on at what temp? The thermostat is set to begin opening at 188 and fully open at 206. Unless the HVAC system is in AUTO, when fans run in slow all the time (A/C function commanded ON) the fans are controlled by the engine coolant temperature sensor and come on in SLOW at 224 and FAST at 236.
