How often should I change the antifreeze for my car?

Generally speaking, it is more appropriate to replace antifreeze every three years or every 50 thousand kilometers. However, it is worth noting that different brands of antifreeze use different chemical components, so the service life is also different. In addition, the service life of the owner's car and other antifreeze will also have a certain impact. Therefore, you can refer to the maintenance manual and antifreeze instructions for details.

For antifreeze, many manufacturers have not clearly defined the replacement cycle. At this time, riders should check regularly to see if the coolant level and freezing point are lowered. Also observe whether the coolant is precipitated and turbid. If there is precipitation or turbidity, the coolant may deteriorate and need to be replaced in time.

It is worth noting that if the coolant level decreases, different colors of coolant cannot be mixed during filling. Even if the colors are the same, it is necessary to see clearly that the brands and ingredients are different, otherwise chemical reactions may occur after mixed use.

After the chemical reaction, the performance of the coolant may be reduced, or even lead to its failure. If sediment is produced, it may block the cooling system, thus aggravating the wear and tear of the engine.
