hello saab municipality! today seems to be the day of the big help calls! with me lies the following problem before: yesterday on the way home after about 200km drive the temp rose in my 9000cse 2.0 LPT almost into the red area. so immediately engine off, ignition on, climateutomaitics on HI and waited, the play three times then I was at home. today the balance tank controlled. kwasserstand was briefly over MIN. 0.5 liters after spilled and tested – temp after approx. 2 0km again shortly before red and balance container brimfully and at the overflow. when controlling the balance container I noticed sugar-like grains both in the lid and in the entire container (outside visible deposits). can it be that this grind clogged the cooling circuit? when I put the climate car on HI came however only cold air! is the whole problem vll back to a defective thermostat? (my thermostat which the large one of the small cooling circuit separates!) also yesterday on the ride ices in the interior did not get warm, or just at first!!! since I am currently dependent on the car I would have to express my opinion quickly and thank you! although I don’t have to stress that normally in this forum ciao franz
