Moin first of all, I am the new one. Shortly before 50, at the corner of Hamburg and for about 4 months proud owner of a 98 NB, 1.6 l. Nice fun car, but just makes me a little bit of a headache. Short story: Monday morning some V-belt squeaking, short gas shock, squeaking away. Nothing at all thought, weather here passed from Frost to “wet warm”. Wednesday there were again V-belt squeaking after about 5 km while driving. Then I noticed that I had no heating. About 1 km further came d The first thoughts were the unpleasant smell, hot cooling water or hot technology. At the traffic lights the temperature went up quickly and I then saved myself 300 m further into a parking lot. With running engine nothing more noticed, after the parking immediately smoke came out of the radiator grill. At the moment a lot of work and always came by the car only in the dark, today it fit times and times made a short check. V-belt squeaks immediately. Already after approx. 5 seconds again smoke formation. Neither in the cooler nor in the balance tank is water to be seen. I find in the net unfortunately no documentary or similar, contributions with similar problems always shoot hair-sharply past my questions or are for another motor… Meaningful: Thermostat replaces fixed, only 2 screws. Zack, end. The questions are: Where is the thermostat sitting? Where is the water pump sitting? Are there known weak points with leaks in the cooling circuit? When I fill the cooling water only with water and then switch, there is a coolant that the engine doesn’t like at all? Let’s do it 😉 Greeting Uwe
