Hello, my XC90 slowly worries me. He’s cracked the 200 tkm mark tonight, that’s a nice thing, unfortunately he has a seemingly insoluble problem. He can conjure coolant away!! That’s what follows. For about 2 years and now 60 Tkm cool water disappears! Performed work and search: First checked for external leaks and searched for Mitllerweil 8 times. A one-week stay at Volvo for diagnosis, with co test and leak test! WITHOUT success. There it was still so that you have filled up about every 6 to 9 weeks from Min on Max. Meanwhile I do this every Sunday. Daily driving distance 60 to 80 km. Heat exchanger in the interior area has no leakage that one could see or feel, the heater I have a week ago with a lot of fluffy egg through the distant fog light cannon? I still have a good idea to wear out this out. Unfortunately still disappears cool water. Kien slimm in the oil, no oil in the water. So CO test did not have to have the cool water here.
