1. Измерьте удельный вес охлаждающей жидкости с помощью ареометра.

1. Measure the specific gravity of the coolant using a hydrometer.

2. Measure the coolant temperature and determine the antifreeze concentration using the relationship between specific gravity and temperature in the table below.


RELATIONSHIP BETWEEN COOLANT DENSITY AND ETHYLENE GLYCOL CONCENTRATION

Example: Safe operating temperature is -15 °C when the measured specific gravity is 1.058 g/cm3 at a coolant temperature of 20 °C.

• If the antifreeze concentration is below 30%, the anticorrosion properties of the coolant are significantly reduced.

• If the concentration exceeds 60%, the freezing point of the antifreeze rises (heat transfer efficiency decreases), adversely affecting the engine. Therefore, make sure the antifreeze concentration is within the specified range.

• Do not mix antifreeze of different brands.

RECOMMENDED COOLANT

Antifreeze Antifreeze concentration in coolant

ANTIFREEZE FOR ALUMINUM ALLOYS

50% [Except regions with tropical climate]

ETHYLENE GLYCOL BASED 40% [Regions with tropical climate]
