    Coolant change

    I'm new to this forum, can anyone kindly tell me what the process of changing the coolant on a 2007 Golf 1.6 FSI is and how to correctly bleed it and reduce air pockets? What coolant type is needed? I need to change the coolant temperature sensor and I believe it's the grey 2pin sensor I need. I read a lot of places that you can just pull out the sensor and put the new one in with minimal coolant loss. If I do this, surely I will need to top up some coolant in the expansion bottle afterwards? I watched some videos and sometimes it seems the rubber O ring gets stuck inside so fiddling with it to try and take the O ring out ends up with losing more coolant right?

    First posts normally go in introductions else you could get a free fix and we never see you again!!!

    Your car spec says 0, is this your 2007 Golf 1.6 FSI or are you trying to fix someone else's as that is what I've added to your car spec?

    Why do you need to change coolant temperature sensor, who told you and have you got an error code scan?

    The newer antifreeze is G13. Bleeding the cooling system can be a pain on some vehicles.

    Yes it's my 2007 Golf. I'm getting error code P2185 - Engine coolant temperature sensor 2 circuit high. As soon as I turn on the car after its been sitting for days, the fan just kicks in straight away and stays on even after I turn it off. Engine temp shows it's gone to 90 degrees very quickly which it can't be.

    I watched a few videos on YouTube about changing the sensor and it seems like the sensor is held in by a retaining plate/clip that you pull up and out and then you pull the sensor out and then you just quickly pop the new sensor in. But my concern is that if the O ring remains stuck inside, it may take a little while longer to get it out and end up losing more coolant. As coolant level drops, I'm assuming it will drop in the expansion bottle so as long as I keep an eye on that then it should be fine? If I'm just topping up lost coolant in the expansion bottle do I need G13 coolant or will off the shelf ready mixed red coolant from eurocarparts or Halfords do for topping up?

    The sensor on the lower radiator outlet is easy to change when the engine is cold but you need the car high up so you can get the lower cover off and it will be messy.

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    It's the sensor on the following photo right?

    Do you just pull the metal retainer bracket out? When fitting the new sensor, do you push the sensor all the way in and then just push the retainer back in?
