How is it that there is less antifreeze in the cold water tank in the weather?

Antifreeze liquid, also called antifreeze coolant, refers to the coolant with antifreeze function. In order to keep the car in use at low temperature in winter, the cooling system will not freeze in low temperature weather. Careful car owners found that the antifreeze would decrease after using the car for a long time. What's the matter?

The first is natural loss. All kinds of automobile oils are lossy. Because antifreeze is responsible for cooling the automobile engine, it is often in a high temperature state. The annual loss of general antifreeze is 10%? About 36% is normal.

According to the technical requirements of NB/SH/T 052 1-20 10 Engine Coolant issued by National Energy Administration, the boiling point of 50% antifreeze is above 100℃, and the loss is mainly natural volatilization. Without replacement, the annual loss of/kloc-0 is 65438. Between 36%.

The second one is that it needs to be added less in a few days, but it needs to be added less in a few days, indicating that the antifreeze is leaking.

Rubber metal pipe fittings, often at high temperature, will age due to thermal expansion and cold contraction. If there is a slight gap, antifreeze will seep out. Water tank pipe, air conditioning hot water pipe, thermostat, water pump sealing ring, etc. Are common parts that cause water seepage. The inspection is actually very simple, because the antifreeze is composed of various additives, and there will be obvious additive deposits at the leakage point. However, due to the small space in the engine compartment and the complex structure of the cooling circulation system, it is difficult for car owners to check it themselves in some places.

The third is that antifreeze enters the cylinder to participate in combustion, such as cracks in the cylinder block, erosion or corrosion deformation of the cylinder gasket, etc. At this time, pull out the dipstick to see if there is emulsifying phenomenon in the oil. Because there are oil passages and waterways on the cylinder block, once the cylinder pad is damaged, the waterways cannot be sealed and flow into the oil passages.

According to the manufacturer's instructions, it is generally replaced every 2 years or 40,000 kilometers, and the longest replacement is every 4 years or 60,000 kilometers. There are several automobile manufacturers, and antifreeze supports life-long replacement.
