Checking coolant density
| - Hydrometer, measure the specific gravity of the coolant.
 | - Measure the temperature of the coolant, and depending on the temperature to calculate the concentration in the antifreeze coolant.
|
Example Safe Operating Temperature -15 ?� C with the suspension and the specific gravity of 1,058 coolant temperature 20 ?� C. |
|
 | - If the concentration of coolant is below 30%, lowered coolant anticorrosive properties.
- At a concentration of more than 60% frost coolant deteriorates. For these reasons, make sure that the concentration of the antifreeze in the coolant is in the exact limits.
- Do not use coolant with another brand of antifreeze.

Recommended coolant Antifreeze | The content of the antifreeze coolant | | Based on ethylene glycol for use with aluminum | 50% (except for the tropical regions)
40% (for the tropical regions) |
The ratio between the concentration of antifreeze and coolant specific gravity Coolant temperature ?� C and a specific gravity of | Freezing Point ?� C | Safe working temperature ?� C | Concentration Coolant | 10 | 20 | thirty | 40 | 50 | 1,054 | 1.05 | 1,046 | 1,042 | 1,036 | -16 | -eleven | thirty% | 1,063 | 1,058 | 1,054 | 1,042 | 1,044 | -20 | -15 | 35% | 1,071 | 1,067 | 1,062 | 1,042 | 1,052 | -25 | -20 | 40% | 1,079 | 1,074 | 1,069 | 1,042 | 1,058 | -thirty | -25 | 45% | 1,087 | 1,082 | 1,076 | 1,042 | 1,064 | -36 | -31 | 50% | 1,095 | 1.09 | 1,084 | 1,042 | 10.7 | -42 | -37 | 55% | 1,103 | 1,098 | 1,092 | 1,042 | 1,076 | -50 | -45 | 60% |
