How often does the car antifreeze change? Is the antifreeze the same as the coolant?

At the wedding banquet of the village party secretary’s son, Xiao Ming on the construction site made everyone laugh: “Car antifreeze is only added in winter. Why is it necessary to prevent freezing when it’s so hot in summer? It’s a waste of money.” Seeing everyone laughing, in order to avoid embarrassment, Aunt Wang at the table next door also chuckled. The owner’s guide will use this knowledge related to popular science to let you go back to the village to be the most beautiful boy.

Is the antifreeze the same as the coolant?

The antifreeze of the car is the coolant, the two are the same thing, the real full name is the antifreeze coolant. Ordinary professionals will be referred to as coolant for short.

What is the use of antifreeze

In short, antifreeze is an important substance in the cooling system. It circulates in the water tank and takes away the heat of the engine through the pipeline. In addition to anti-freezing and cooling, it also has excellent features such as summer anti-boiling, rust removal, and anti-corrosion. Therefore, the argument that southerners do not need antifreeze is simply not tenable, because antifreeze is really more than just antifreeze.

How often does the car antifreeze change

The replacement period of the antifreeze is 2-3 years or about 60,000 kilometers. Generally, the antifreeze can have a better effect during this period. Of course, if the vehicle is used frequently or the driving environment is bad, it should be replaced in advance. Everyone's driving conditions are different, so such data reference is not representative. Some judgment methods are introduced below. If the following situations occur, you should consider replacing the antifreeze.

1. The color of the antifreeze in the pot has been changed, which is obviously different from the original color;

2. Accumulated or floating impurities are seen in the antifreeze;

3. The liquid level of the antifreeze has exceeded the minimum limit position;

4. The instrument detects that the freezing point of the antifreeze is insufficient;

5. The engine temperature is too high. (It may not be a problem with the cooling system, it needs further investigation)

If the car owner doesn't want to remember so much, he usually has the habit of maintenance, so don't worry. Because in the maintenance items, checking the antifreeze is a necessary procedure, professionals will inform us whether it needs to be replaced.

★expand:This knowledge you must understand

1. Can I add water to the antifreeze?

If you want to use it in an emergency, you can add a small amount of purified water, but you must change it back to a regular brand of antifreeze as soon as possible, and it cannot be used for a long time.

2. Can antifreeze be mixed?

Antifreeze should not be mixed. Some people on the Internet say that antifreeze of different colors should not be mixed, causing some car owners to misunderstand. It is believed that as long as the antifreeze of the same color can be added at will, this is also not allowed.

3. What are the undesirable consequences of mixing antifreeze?

Because even if the color is the same and the formula is different, mixing may also cause anti-chemical reactions between different ingredients, causing the function of the antifreeze to fail. The freezing point changes and the dirt increases, which causes the coolant to freeze and crack the water tank in the cold, and the inability to cool down in the summer causes mechanical damage to the engine and even blows the cylinder.
