Extraction
1. Disconnect the battery cable with a minus sign.
2. Drain the liquid from the cooling system.
3. Unscrew the thermal switch on the left side of the radiator and the o-ring 15 (pic. 2.3).

Examination
4. To check the thermal switch, it is necessary to hang it in such a way that only that part of it, which is usually screwed into the radiator, is immersed in the vessel with liquid. Connect in order the thermal switch with a 12-volt test lamp to the battery. Gradually heat the water and measure the temperature with a thermometer. The test lamp should light up at a certain switch-on temperature and go out after a certain switch-off temperature. If the lamp does not turn on and off at certain temperatures, it is necessary to replace the thermal switch with a new one.
Switching temperature 93-98°С
Switch-off temperature 88-93°C
Installation
Installation is carried out in the reverse order of removal. During installation, it is necessary to install a new O-ring under the thermal switch and tighten it with a torque of 25 Nm. Fill the cooling system with liquid.
