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.
What temp does the fan turn on? I towed my buddys toybox yesterday that was about 12k lbs. This was the first time I towed with that much weight with my new coolant temp gauge. The fan kicked on at 230* on my guage, is that when its supposed to? I have the last flash and thought Ford lowered the temp for the fan to turn on from the earlier flashes.
