Engine Coolant Concentration Test

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.
