5.3.5. And having added control of level cooling liquid

"Daily service"
1. Check the level of cooling liquid on the cold engine — the cooling system is not under pressure.

Fig. 4.43. Broad tank: 1 – safety ring; 2 – laying; 3 – sensor; 4 – a float with the lever

2. At the cold engine level has to reach a dividing fold between the top and lower parts of a tank (fig. 4.43). At the same time the float of the sensor holds the top position. On the hot engine the level of liquid rises above.

3. For a doliv of liquid open a jellied mouth (fig. 4.44). At the hot engine take a cover a dense rag and open slowly to balance pressure of hot liquid with external. If you too quickly open a cover, liquid under pressure will throw out from a mouth.
4. Do not add liquid above a dividing fold of a broad tank, cooling liquid when heating will extend and surplus will throw out it outside.
