    Copenistas,

    As you can see my cooling fan is running when the engine hasn't warmed up.
    It could be the sensor but i couldn't be that lucky. Probably the head gasket.
    Mind you, the temperature gauge is rock solid on 90 degrees.
    Anyone know where I could get a sensor and where it is located on engine ?

    Switch the a/c off and then see what it’s like.

    Could it be something to do with the heater core as that blows hot air from the hot coolant into the cabin?

    Used to have a White Copen, but I sold it in 2023
    there is something called a condenser which sits right in front of the radiator. It needs to be cooled in order to provide cold air for the AC. Thats why the fan is running :D
