Hello everyone, I have been driving a Daewoo Matiz 0.8S since approx.2 and have the following problem since the summer 09: if I drive with the car iwohin then the motor warms up quite quickly… I have read that the thermostat does not turn on from a cold start to approx.75°C operating temperature, and only from 75°C gives a way free that should ensure that the motor does not overheat. now it is with me that from a certain distance it is normal to drive( give little gas and early This sounds like you switch on the air conditioning system. also the fan goes on when I give a bit of power, i.e. more gas and a little later switch up. I recently changed the complete coolant, because I thought it might be because of it… futile 🙁 and if it helps: if the engine hasn’t run warm yet and the fan hasn’t started to get loud, I can use the air conditioning system. on and off. but as far as the fan has become louder and I turn on the motor from and on again, and then nocj the climate on, so I can’t get it out anymore, despite the exclusion button… well I hope I have given enough info and one of you good people can help me 😉 many thanks in advance
