How to clean the scale in Lefeng coolant pot?

The source of scale in the kettle of cooling water tank is that the coolant is not paid attention to and replaced for a long time, which eventually leads to scale. Coolant also needs to be changed regularly. If there is a lot of scale in the kettle, there will be some scale in the cooling circulation system. I suggest you go to the maintenance station to clean the cooling system. You can remove these scales with water tank cleaner. In normal driving, excessive scale will affect the normal heat dissipation of the engine. In general, change the coolant every 2-3 years, and check the freezing point of the coolant and the quality of antifreeze every winter.
