°C | -10 | -14 | -15 | -18 | -20 | -23 | -25 | -27 | -30 | -33 | -35 | -37 |
Volume % | 21 | 26 | 27 | 31 | 33 | 36 | 38 | 41 | 43 | 46 | 48 | 50 |
A = Anti-freeze concentration determine, in volume%.
C = Total coolant fluid capacity, in liters.
E = 100 - Anti-freeze concentration determine, in volume% (A).
F = Anti-freeze refill quantity, in liters.
Calculation example:
Reading value found on the tester = -20°C.
Refer the concentration table and find the value for -20°C, which is = 33%.
Apply on the below formula to find "F" value.
A = 33%
B = 50-33 = 17
C = 30 liters
D = BxC = 17x30 = 510
E = 100-33
F = D/E = 510/67 = 7.6 liters
