Greetings friends Peugeot partner (2000 model) I bought in the winter normally the temperature certainly did not cross the middle line. It doesn't say 50-70 etc in terms of numerical level so I can tell the temperature level :) I don't know if it's actually a problem, but the car crosses the middle temperature line, I think it's 90. I had an old Tofaş Şahin vehicle. I had a summer winter thermostat. I don't know if there is a thermostat.
