It can be cleaned by disassembling it, and it can also be cleaned without stopping the machine. You can directly pour the special scale cleaning agent into the car's water circulation system, let it soak, idle or drive for 20-30 minutes. Then drain the descaling agent inside the water tank and system. Add water and rinse it repeatedly to effectively clean the engine. Scale, rust, mud and various harmful substances in the water circulation system.
If the water tank is not cleaned properly, a large amount of scale will be produced, which will greatly affect the heat dissipation of the water tank. Because the thermal conductivity of scale is very low, only 1/25 of that of cast iron and 1/50 of that of brass, the scale formed in the cylinder lining and cylinder head water channel will cause the temperature of local areas to rise due to poor heat dissipation, which will cause the engine to Cracks occur in weak areas and the cylinder head deforms. It not only worsens the heat dissipation performance of the cooling system, creates local high temperature areas, worsens the lubrication conditions, increases the engine temperature, and accelerates the wear and tear of the engine system; it also blocks the heat dissipation pipe or cooling system pipeline, etc., greatly reducing the heat transfer efficiency. Overheating the engine directly endangers the safety of the driver.
To avoid the formation of scale, we must pay attention to the selection of coolant in the water tank. Many drivers do not pay attention to the use and pros and cons of coolant, and usually only add ordinary water to the water tank. Calcium and magnesium ions in water can easily form inorganic salt scale in the cooling system. When these scales form in the cylinder lining and cylinder head water channels, they will affect the heat transfer efficiency, cause local high temperature areas, worsen the lubrication conditions, and accelerate the wear of the engine system. High-quality engine coolant is composed of polyester-grade ethylene glycol, distilled water, scale inhibitors and other raw materials, which can effectively prevent the formation of scale, partially remove the original scale, and improve the efficiency of the cooling system.
