4.3. Check of density of a cooling liquid
PERFORMANCE ORDER
1. Ареометром measure relative density of a cooling liquid.
2. Take temperature of a cooling liquid and depending on temperature calculate concentration of antifreeze in a cooling liquid.

Parity between concentration of antifreeze in a cooling liquid and relative density

Temperature of a cooling liquid °C and relative density
Freezing temperature °C

Example

Safe working temperature–15°C at the weighed relative density 1,058 and temperature of a cooling liquid 20°C
The prevention

If concentration of a cooling liquid below 30 %, anticorrosive properties of a cooling liquid go down. At concentration more than 60 % worsen frost resistance of a cooling liquid.
