Hello guys, I am proud owner of a Saab 9-5 2.3 LPT Kombi, BJ 2001 with at the time 197`000km. It is not special equipment, handshifting, and velour seats. Nevertheless, I find the ride comfort and generally the Kombi itself great! I need the Saab daily for the work path, i.e. 40 back and 40km. Live in Switzerland, and also my driving style is rather “quiet” than hectic, should be hot is never really driven over 3-4ts tours, max 140 km/h. Service are from the front I have now made a service again, after exactly 10`000km, incl. oil + filter, all liquids incl. cooling liquid. So far so good. My problem: I drive the car to work, all good, the SID indicates in the CHECK “OK”. Cars park in the morning, in the evening car, and see here, the SID shows “control cooling liquid”. So hood, and the cooling liquid is really about 1cm below r brand, so I bought for the tank, coolant, lid on, and suddenly a rush and bubble and the cooling water is on the mark again! Car started again, SID says, everything OK! I have had this already about 2 -3 times! I see no loss, also no oil in the cooling water, no suspicious smoke developments from the exhaust. The temperature display of the cooling water is always marginal over the middle, but remains there how nailed! Does anyone know the problem? My opinion na The pressure in the system will not “let off”. I’ve already read a lot, could it possibly be the cooling water cover? I’m perplexed, I hope it’s not the ZKD! Thank you for your efforts, gruss KAE
