vaporization, you should add the distilled water or the demineralization water. After
adding distilled water or condensed liquid, you should stir it evenly then check the
anti-freeze solution’s density, till you get the density corresponding to the freezing
point you need. Never add common water (such as river, lake, pond, well or tap water),
the foreign material in it will consume certain part of aseptic.
6) Don’t put off anti-freeze solutions of different brands; this will damage their respective
anti-corrosion capacity.
7) The life cycle for long-term anti-freeze solution’s tenure of use is usually 1~2 years, you
should change it when it is overdue. To reduce any waste, when it is out of its life cycle
you may first check the PH value before changing. If the PH value is higher than 5.5,
you may continue using it; if PH value is lower than 5.5, you should change it timely, or
it will hasten the corrosion of the cooling system. When the PH value is lower than 5,
you may add prolonging agent into the freezing liquid to extend the life of anti-freeze
solution by one year.
8) Don’t suck ethanediol into your mouth because it is poisonous and has a damaging
effect on the liver, wash after it contacted your skin. Sodium nitrite can cause cancer,
don’t pour the waste liquid around, which will pollute the environment.
