Relationship between Coolant Concentration and Specific Gravity
CAUTION:
^ If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely affected. In addition, if the concentration is above 60%, both the anti-freeze and engine cooling properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain the concentration level within the specified range.
^ Do not use a mixture of different brands of anti-freeze.
Example
The safe operating temperature is -15 °C (5 °F) when the specific gravity is 1.058 at the coolant temperature of 20 °C (68 °F)
