Is there a car that hasn’t changed antifreeze for 10 years?Does the car antifreeze hardly need to be changed?

There are cars that have not changed antifreeze for 10 years, but mainly for some luxury cars, such asBenz. There is almost no need to change car antifreeze. The antifreeze used in most family cars has a general cycle of 2 years or 40,000 kilometers. For long-running vehicles, such as taxis, it can be replaced once a year. However, the specifics still need to be judged according to the maintenance manual or the actual situation.

Antifreeze is called antifreeze coolant, which prevents the car from cooling and icing when parking and causing engine damage. When using antifreeze, remember not to mix different models and brands of antifreeze, and do not mix with water at the same time.

If other antifreeze fluids are mixed, since the various additives contained in different antifreeze fluids are different, a chemical reaction may occur, causing the antifreeze fluid to lose its due effect and even damage the engine.

If the antifreeze is mixed with water, because the water contains many minerals, these minerals will form scale and deposit on the metal surface after heating and evaporating. If the scale deposits in the water tank, it will affect the heat dissipation effect of the radiator; If scale is formed in the cooling system of the engine, the water channel will be blocked and normal circulation will not be possible, which will easily cause the engine to locally heat up and cause malfunctions.

It is more important to note that the antifreeze liquid should not directly touch the skin, because the ethylene glycol contained in it is an organic solvent, which is corrosive to a certain extent, so avoid direct contact with the skin.
