Check the antifreeze concentration
| Fig. 2.6. Measurement of specific gravity coolant via hydrometer
|
Measure the specific gravity of the coolant using a hydrometer. Measure the temperature of the coolant and determine the concentration of antifreeze based on the relationship between specific gravity and the temperature on the basis of the above table 2.4. Example: the temperature of the safe operation of -15 ?� C, when the measured specific gravity of 1.058 g / cm 3 at a coolant temperature of 20 ?� C.
Recommended coolant If the concentration of coolant is below 30%, then the coolant corrosion resistance is significantly reduced. If the concentration of more than 60%, then increased the crystallization temperature of antifreeze (reduced heat transfer efficiency), impacting negatively on the engine. Therefore, make sure that the level of concentration of antifreeze is within the specified range. Do not mix different antifreeze
