2.14.2. Check of level and density of cooling liquid

In completely filled cooling system liquid level in a broad tank on the cold engine has to be 25-30 mm higher than a tag of "MIN" put on a broad tank.

Level of cooling liquid is recommended to be checked on the cold engine as at its heating volume increases and at the heated-up engine the level of liquid can rise considerably.

If necessary check the areometer density of cooling liquid which has to be 1,078–1,085 g/cm3.
If level in a tank is lower than norm, and the liquid density stated above, then add the distilled water. If density normal, add liquid of that brand which is in the cooling system. If density of liquid is lower than norm, add Tosol-A liquid.
