After my current daily runs again and I am on vacation, I have once recovered my thermostat and it seems to work perfectly in the cooking pot, although everything speaks for the fact that it has to clamp open. So, although no touch sample on the hoses made, but here the problem picture – the engine (B6 SOHC) is quickly warm in the stand, display is made nau between C and H. – If you drive now, the temperature drops depending on how fast and how cold it is outside – the faster, the colder (driving wind). I don’t know what the display range is from the instrument, on the highway it sometimes goes back to under the C-marker – Depending on the engine temperature increased speed, already often over 1300 rpm after highway ride. – Heating leaves to wishes – fuel consumption I can’t judge, because I bought the defect so. What closes That the indicator goes, because it rises up to half, when it shows cold, the heating is cold and the motor rotates more; if that fits also the temperature generator should work accordingly and the thermostat is simply defective and cold cooling water hunts through the cooler. My golf, on the other hand, always reads 90°C, unless you shoot the heating on maximum, while you tuck along the country road with 70, only then it actually goes direction 70. The thermostat is z u, closes and opens in the pot at 88°C, the ball valve moves freely. So everything actually top. So now the question arises, what is it then…
