Hello together, My problem: The water in the balance tank cooks when opening the closure, the temperature of the indicator slowly climbs up to the red area and then jump to the red area with light on the indicator lamp, light water loss, approx.0.5 liters/100km fan does not sping on In the lower speed range stutters the motor(in idle) this goes back to the normal range as speed rises Then the K described in the first section och, which brings the temperature back to the normal range by refilling approx. 0.5 L water, and the same starts from the front. When the cooling water hose is pressed with an open balance tank, it feels empty, when the container is closed it is under pressure but it does not feel like it is filled with liquid. am grateful for every tip
