    ..If you are not sure what you are doing.
    I learned my lesson the hard way.

    It all started few days ago, when i noticed that my husky was running hot and ventilator didn't want to start. I checked my water level, it was half empty, so I put some water in it, like I do in my car.
    I checked for leaks, nothing found.

    So I left it running idle for like 15-20 minutes, to see if ventilator will eventually start.
    It didn't.

    Instead a BOOM happened and the radiator hose near water pump blown.
    So did my leg with it, and I feel lucky that this happened to my leg and not to my face, cause I was down there checking for leaks all that time.

    Be careful with these things guys!

    What could cause this "hose explosion" except ventilator issue?
    Faulty radiator cap?
    Tank problem?

    Wow, get better soon !

    By the looks of it it seems to be a radiator hose with a 'T' in it and that joint failed, those parts are always more delicate than a straight hose..

    But I would agree that the radiator cap should have blown the excessive pressure before rupturing the hose. In the service manual there are instructions on hoy to test the cap pressurizing the system with air.

    Cheers.

    Is there a thermostat? Those are common failings

    I believe it was a combo of failings, cap didn't worked for sure, and then temp sensor or cooling fan too. I will leave bike to my mechanic, I won't try to solve this by myself cause it has become a bit dangerous..
