A question for the 2.5 he drivers regarding the engine temperature. I converted and implanted a Saab engine block on Opel because I broke the old engine due to a cooler spacer (triggered by defective cylinder head gasket). The new one runs without problems and I am actually very satisfied. My engine temperature is constantly between 90 and 92.5 degrees, which is also quickly reached. Since it is getting cold now, one of course turns on the heating. rd but not really warm. I once pulled the fuse 18a in the engine compartment for test purposes (this is responsible for the climate cooler fans). Then the engine temperature climbs up to approx. 95 – 97 degrees and then cools back to 92.5 degrees, then the whole thing repeats itself. At these engine temperatures my heating gets really warm, not to say hot. Now my question: How warm is your V6 according to the display? What can I do to keep my heater as warm as it is with drawn I don’t want to and can’t leave the fuse away because the engine is not cooled after setting off. I have renewed in the course of the engine change: 1. Thermostat (92 degrees from Behr) 2. Heating valve 3. Water pump 4. Cooler 5. Cooling water P.S. If the thermostat starts to open at 92 degrees and is completely open at 97 degrees, but the engine has loudly at point 92.5 degrees, in my opinion the thermostat does not have to have opened koplett and there the error lies. n, right? Would it be possible that the thermoswitch of the climate cooler is no longer in order? Or can it be that the heat exchanger of the heating is no longer so permeable by deposits and for some time on the dry? But what does not explain that at 95 –97 degrees engine temperature the heating gets really warm. Question about question, hope me a advice from you how I can solve this problem!
