4.3. Check of density of cooling liquid
PERFORMANCE ORDER
1. By the areometer measure specific weight of cooling liquid.
2. Take temperature of cooling liquid and depending on temperature calculate concentration of antifreeze in cooling liquid.

Ratio between concentration of antifreeze in cooling liquid and specific weight

Example

Safe working temperature – 15°C at the weighed specific weight 1,058 and temperature of cooling liquid 20°C
Prevention

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