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.
There is a temp sensor in the engine which tells your fan when to kick on. If that is faulty, the fan won't turn on, and it will overheat when idling. If it overheats while idling, I would look at the fan to make sure it's doing it's job...when I say look at the fan, I mean check the temp sensor, check the relay, and check the fan itself.ome things you might turn to... - Low coolent level-Thermostat is stuck-A bad water pump-Faulty coolant temp sending unit-Faulty engine temp sending unit? - Faulty engine fan relay, or fan itself is bad-Radiator is plugged A faulty temp sensor and/or gauge can read high heat, but be wrong.
