Hi Community, I have determined the following after the exchange of my monovalve: 1. Monovalve Tacks always up and too is this normal ? Or shouldn’t the valve be open at a certain point at a temperature ? Or can it only be open or too and if yes, is it normal that it tacks like this every 5-8 seconds ? 2. Do I probably have a water noise at the windscreen during the tacking as if something were swarming or air in a system . That is also not possible since d He sits heat exchanger on the right (passenger side)? How does the cooling circuit vent? Thank you for your feedback and experience.
