hello, I’m new here and I’ve already hijacked good advice on my topic, so now I have a new question, eigtl. I thought I knew where the problem lies with my car, but now I’m skeptical… my temp display gets warm very quickly, at stop+go I have to heat in order not to get into the red breich…, if I turn off the mor also the fan does not run after, etc… therefore I conclude that only the small. cool circuit “is active” and just my thermostat now I’m just reading another post and it was there that – if the thermostat is broken – the big cool circuit is active ? if so then my problem lies where different …. can you “taste” it somewhere whether only the small or anyway both cool circuits play along? or where is the limit (?) the thermostat sits in this thick, soft hose, or? would I be very happy about an answer, I know myself with car + technology so something from at all….fa christoph s already embarrassing ^^ mfg christoph
