    Coolant usage

    Just noticed my 2020 XR coolant level below the min mark on the expansion tank. Bike has 3500 miles. Anyone else notice this on their new model XR.
    Just a bit concerned that it should be using any coolant at this stage!

    Regards

    The first Gen XR had some issues with water pump leaks (mine included) Not sure if it's a reported problem for the new model  :027:
    Could see dried up collant streaks on the cat and on the plug at the base of the water pump.
    But it could just be that there was a bit of air trapped in the system which has now gone.
    Suggest a top up to max level and monitoring over the next few days/weeks  :028:

    The 2020/21 XR has an "internal water pump/oil pump" combo....I'm guessing if the water pump leaks, we'll probably see plenty of custard in some of those engines..! :084:

    Custard is alway the tell tale sign, if there isn’t do what has already been suggested in top it up and keep an eye on the level,mine has always been low as well.

    This post prompted me to check my 2020 coolant level,and it too is indeed just bellow minimum, I'll top up tomorrow and then keep an eye. to be honest I didn't know where it was ,it certainly is not convenient to top up or to check either. Easily overlooked.

    After speaking with the BMW tech guy it’s perfectly normal. I have checked brand new machines and they are the same. Another forum I use has thrown up the same results as well for the new XR. If you top it up it will resettle eventually at the same level.
    Best just keep an eye on it to be in the same side.

    Coolant probably settles after it's initially filled at the factory, so you need to add some after a break in.
    My XR was slightly low on coolant too (level just at the minimum mark), so I've added 100-150ml of distilled water and now it's as it should be - between the max/min marks.

    Be very careful not to add anymore water, you will raise the freezing point of the coolant too much and could result in a burst hose or much worse if you live in or store your bike in sub zero temps.

    I'm aware of that. XR's cooling system takes approximately 3L of coolant. Its freezing point (from factory) is -36 deg C. So adding 100-200ml of distilled water to the mix has virtually no effect on its freezing point.
    In my opinion, adding up to 500ml of water is completely safe. Provided that you don't live in the Arctic regions :001:
