Hello, my problem is that my car gets warm after a certain time, so the water temp. goes to the red. New thermostat is in it. In the water is extremely much dirt, cancel none determined. Warm it only after mountain rides or after longer time on the highway. when one then switches down a corridor the temperature settles again somewhat. but remains clearly above the should. have now found if one turns cooling water behind the whole circuit again ew ig good. Car doesn’t get warm, stays around at 90 degrees. So if you open the overpressure lid and empty water there. But what exactly is broken I don’t know, does that have something to do with the cooling. or is that on the engine?
