Massive coolant leakage

Hi, today I was watching my plane and I saw that there is leakage sign's on the ground.
I opened engine hood and I saw that everything is dirty of coolant.
I looked every clamp, wather pump but everything was dirty. In my overflow bottle it was under min level (but it itsn't empty). Before last flight I had half level between max and min.
Last flight I made about 1 hour with more covered radiator. I had about 107*C CHT and 88*C Oil.
I cleaned up all, fill coolant (in main bottle i had good level).
I made test run (up to 107*C CHT) and there is no signs of leakage.
Wather pump looks good (a some time after test I can see a little of dirty cooland near drain hole but I think it's normal.
In overflow bottle level raised during test (hot engine) and fall down when cooling.
I looking for reason of last leakage. Any ideas? I wondering it is possible that cooland was boiled when I had about 107*C CHT during flight? My sensor is on right, front head.
