The air remained in the system, the thermostat did not open, so the fan did not work. He said that there was still air in the system, but they did not admit their mistakes. On principle, I then bought antifreeze again and was filled with the device again. Only then did the thermostat open and the fan was running. For such types of craftsmen, I left with a minus of antifreeze 8,500 and 5,000 tenge again for the replacement of antifreeze . I advise you not to go to this warm world.
