Having problems with your 2005 Mini Cooper ?
Temperature gauge back and forth between normal
\015 2006 mini cooper, temperature gauge back and forth between normal and hot hen the fan comes on, has coolant, any ideas\015
The fan comes on and off based on the "temperature sending unit" thats a thermal switch mounted on the radiator .. it is normal for the temperature to fluxuate as the fan turns on and off .. if it is allowed to get too hot before turning on then the temperature sending unit should be replaced ...while the car is moving the fan may never come on and isnt needed as long as air is flowing through the radiator .. as long as you are not loosing coolant then the temperatures are probably within proper range ... a sticking thermostat can also cause increased temperature range fluxuations .. that will show up as large swings of temp while driving .....
