Measure the temperature and specific gravity of the engine coolant to check the antifreeze
concentration.
Standard value: 30 -
60%
(allowable
concentration range) Recommended antifreeze: DIAQUEEN SUPER LONG LIFE COOLANT or equivalent
caution
If the concentration of the anti-freeze is below 30%, the anti-corrosion
property will be adversely affected. In addition, if the concentration is above 60%,
both the anti-freezing and engine cooling properties will decrease, affecting the engine adversely.
For these reasons, be sure to maintain the concentration level within the specified range.
