    Noticed coolant level dropping over time from my 1050.

    Had a look and noticed this.

    Anyone know what this is and how to fix?

    Thanks

    That's the fuel line quick disconnect, so that's probably petrol.

    As above it’s your petrol quick disconnect. Squeeze the silver disc in the middle and pull apart. Clean up, line it up and push firmly together until it clicks together.

    Thanks I think it must be leaking coolant higher up near the radiator and it is running down the fuel line as liquid is red

    Will investigate further

    Could be the radiator bleed screw or a hose. Need to remove the tank to get a better look at the source. Not hard to do but easier with a near empty tank.

    Ok thanks will have a look

    Do you need the tank off to get to the bleed screw?

    Most likely as the radiator is covered by the plastics. For how long it takes to remove it, you might as well make it easier to work on.

    Very common for the hose clamp on the radiator side of the hose to be loose.

    You said red...both my 1190 and 1290 have yellow coolant in them so check the right side and see what colour yours is.

    If in doubt pull the tank,very easy and quick.

    Rottweiler web site has a video showing how to pull the tank

    The top radiator to hose connection started leaking from mine when it was a couple of years old.

    I just tightened the jubilee clip up with a screwdriver. You can do it through the gap between the painted tank cover plastic and the black tank (where your left knee goes).

    That's in about the right place to run down the fuel line.

    Most 1190's use the red coolant.

    Check the front for damage in the same but I think it may be the hose above it. Did any of the clamps have play in them.

    Did you check the bleed screw on top of the radiator?

    If you clean it down and see if it reappears, which hopefully it won’t. If it does you may have a fault in the radiator.

    Will check hoses above again as you make a good point would explain why it is dripping onto back of rad and fuel line

    Also only seems to lose coolant when running no drips when left overnight under bike

    Cheers

    Yes bleed screw is tight and no signs of leakage

    Rad will be expensive. Ever tried radweld or similar on a bike?

    An old trick was to cover the pipes in talc powder. Any leak will leave a trail through talc. Obviously you’ll not be able to ride or the talc will blow away. Should work on the radiator too.

    Is your bike still under warranty?
