BMW N20 “Mickey mouse” piece from coolant hose to cylinder head. How to remove original part and hose clamp. I broke out the old piece in order to remove the non-adjustable hose clamp. I used pvc cutters to cut into the top of the old piece and then used pliers to break it further. The was still a ring stuck in the hose where the hose clamp was. I used a 90° hook pick to pick it out. Hope this helps.
