    I was in the middle of a DS ride in NW Wisconsin last weekend with the 950, and my buddy noticed some fluid drooling down the left fuel tank below the radiator fan. Of course, I hoped it was just water from some of the puddles we roosted, but later in the ride it became more pronounced, and the unmistakable purple color of Engine Ice was evident. I loosened the radiator cap to minimize the pressure in the cooling system, and headed for home with some extra water, just in case.
    Made it home with no issues, and minimal coolant loss, and pulled out the radiator to see what happened.

    Here's the tiny leak, in the middle of a spot rubbed by contact with the radiator fan housing-

    The post for the upper-left fan mounting screw protrudes just enough to touch the rad core-

    Another view, with the fan shroud pulled slightly to the right to show where the interference is-

    My 950 Adv has 40k miles, so it took quite a while to wear it's way through the tube, but it might be something you want to look at before it strands you somewhere unpleasant, ( like Wisconsin).

    good catch although late. repairing that shouldn't be an issue if handled by a good radiator repair shop.

    thanks for posting this. i'll defn check mine out and do something preventive if it warrants it.

    Unfortunately, it looks like you would have to unbolt the radiator and pull the left side hose to get enough clearance to unbolt the fan shroud to get a good look at the area. At that point, you might as well grind down that post to maximize it's clearance to the radiator.
    That would also be a good time to check those valve clearances, folks. I know I will.

    How many miles of rubbin did it take to cause the problem ?
    My 04 has 30k miles on it....can it wait till winter down time?

    40,000 miles. Since winter is almost here, and the leak I experienced was very small, I think that's just fine.
    If you are heading out for a long trip, you might want to check this first.
