Hello omega friends! I found nothing suitable in the forum despite a long search. My basic problem is that the heating control valve licks again and again after several replacements. In search of the why I also asked myself the question, whether the pressure in the cooling system is perhaps too high, i.e. whether I might fill the coolant balance tank too full. CO-test made because of ZKD. Is fine. I upload a photo for this. The container obviously does not sit horizontally. right in the engine compartment. If I fill the water up to the arrow tip on the right side, the water mirror on the left reaches to about the upper edge of the overflow hose. Mind you, in the cold state. Can this be correct? Is the balance tank not sitting in it properly? I also have another question: On the second uploaded photo you can see behind the coolant balance tank (to the vehicle interior) a cable, which I fixed so for the photo. I just hung down, which I noticed for some time after the purchase. On demand at the FOH he said, he doesn’t know that either, but it doesn’t have a function. The Opel has always run so perfectly with the free hanging cable. Can anyone say anything about it? I look forward to your contributions. Thanks in advance and many greetings
