    I have a haul truck that has an cummins L10 motor in it and the fan will not automatically engage and disengage. At the moment to I have to manually engage the fan clutch by a switch in the cab. Does anyone know where the fan switch is located or if the below picture is it or if this is just a high lo coolant sensor or not

    I would not thank that should be it because it is above the thermostat. 10,s here normally have switches in the side plate under the exhaust manifold.
    L10 with high flow cooling in a truck? What are you driving?
    By the way. Your fan belt is worn out.
    Should be a part number on that switch. Google it.
