Why it is necessary to flush the coolant
The reason why the coolant needs to be flushed is that the product may deteriorate after repeated use and is not resistant to freezing and boiling. As the engine contains many parts that may rust, the coolant will absorb rust and deposit it in another part of the car during circulation. However, over time, these particles will accumulate in the coolant, so it will not work. Regular flushing keeps the coolant clean and prevents plugging.
