1. Principles of selecting anti-freeze solution
1) Select anti-freeze solution of different freezing points according to the ambient
temperature.
Its freezing point should be approximately 10
℃
lower than the lowest temperature
recorded in the region’s history.
2) Select anti-freeze solution according to the number of vehicles and
vehicle-concentration.
For those units or departments with quite a number of vehicles that are more often used
in one region, small-package anti-freeze mother liquid can be selected, which is stable in
performance and convenient for transportation and storage. It can also be modulated in
many flexible ways according to the use condition, achieving conservation and
practicality. If there is only limited number of vehicles and they are used in different
regions, you can choose the direct-use type anti-freeze solution.
1)
Use high quality anti-freeze solution, never use inferior quality ones.
High quality anti-freeze solution is usually certified as passing the inspection by the State
designated inspection stations. From the exterior appearance, it should be crystal clear,
not turbid and have no foreign material or irritating smell. The external packing should
bear detailed information on the manufacturer name, product instruction and explicit
indications. Inferior quality anti-freeze solution will not be able to be anti-freeze and
anti-boiling; and quite on the contrary, it will accelerate corrosion to the cooling system.
2)
Use anti-freeze solution that matches the rubber sealing component/pipe.
Anti-freeze solution should have no side effect on the rubber sealing component/part,
such as swelling or encroachment.
