Mini Countryman R60, cooling water dripping.

Hello you love, Unzwar my beloved Bully zicks something around ?? (Mini Countryman Cooper S R60, BJ 2010, 1.6 184ps) At the beginning of the week I noticed that a puddle was created under my mini. Didn’t think too much about it before. However, I parked the car yesterday and saw it dripping out. So the bonnet opened and noticed that the cooling liquid was below the minimum. On the ground one also saw that it was blue/greenish. Was then today At ATU and he gave me new cooling liquid, distilled water and a sealant. So I filled everything nicely and drove off and turned the heater up completely. Afterwards I parked and watched again if it has become less. That was not the case, however, I heard it in the inner drop. The stain is rather centered on the right side. Inside I also see on a carrier that it is wet and there also a small puddle. ze collects, but you can’t see from where it drips. Do you have any ideas about what it might be? Recently my control chain and my climate capacitor were exchanged. Can it possibly have something to do with it? I’ll take some pictures and hang them on afterwards. I’d be very happy about answers.
