Which two ports are there for water tank and antifreeze?Is the coolant and antifreeze the same port?

If the car has two ports for water tank and antifreeze, when replenishing antifreeze, add it from the filling port of the antifreeze kettle. Because the filling port of the water tank is generally used to replace the antifreeze of the whole vehicle or for depressurization or exhaust when the antifreeze is in a special state.

Coolant and antifreeze are the same port, and there is a slight difference between coolant and antifreeze. Antifreeze is not exactly equal to coolant, and coolant is equal to water plus antifreeze. The full name of antifreeze liquid is antifreeze coolant, which means that it is a coolant with antifreeze function, but it does not mean that it can only be used in winter. In fact, it is necessary to use antifreeze all year round. Antifreeze has the characteristics of antifreeze in winter, anti-boiling in summer, anti-corrosion and anti-scaling all year round.

Coolant refers to the liquid that can cool the engine. It can be water or antifreeze. If it is water, the limitation is relatively large, and it will be restricted by the season.

When using coolant or antifreeze, it should be replaced regularly, because the performance of the coolant or antifreeze will change and gradually decay if it is used for a long time. If it is used for a long time without replacing the antifreeze, it will cause the engine The cooling or working environment is affected, and work efficiency is reduced. Therefore, regular replacement can better protect the engine and make the engine run more smoothly.

In general, the replacement cycle of coolant or antifreeze is 2 years or 40,000 kilometers, but this is only a reference value, and it depends on the usage of the coolant or antifreeze. If the replacement cycle is not reached, the coolant or antifreeze If the liquid has deteriorated, it should also be replaced.

When using antifreeze, remember not to mix two different antifreezes, because different antifreezes have different ingredients and additives, and they may react when mixed together, which will cause the antifreeze to fail or even damage the engine. . Also, according to the local minimum temperature, choose an antifreeze with a suitable freezing point to avoid freezing of the antifreeze due to low temperature.
