    Hi all I'm new and I was hoping someone could help me with a problem
    It looks like the thermostat is stuck open and my electrice fan is stuck on all the time
    Are these connected
    Or do I have two problems
    Thanks in advance
    Jeff

    From memory the fan runs most of the time - but at different speeds depending on engine temp. Where is the temp guage sat on the dash? It should always be dead on 12 o'clock position once engine is up to temp.

    Im sure my electric fan cuts in and out when needed i can hear it when it does the viscous fan on a auto car might move all the time because its driven off the water pump pulley etc i think

    If the needles in the middle and not over heating could be a dodgy relay or switch not cutting the fan out

    If the thermostat is stuck open the needle wont reach 12 quickly allowing more coolant to the radiator allowing less efficient running of the car easy to change 30 minute job i got one off ebay about £40 it was wahler brand which to my suprise when removing the original one it was the same brand...bonus

    If cars warming up normal or not overheating for fan to stay on then id think its a relay
