Automobile engine coolant is the cooling medium used in automobile engine cooling system. The reasonable choice of coolant by Benz car repairmen can not only effectively guarantee the normal working temperature of the engine, but also prevent the cooling system from being damaged in the severe cold season; Blind or even wrong selection of unsuitable or deteriorated coolant can not guarantee the normal operation of the engine cooling system, but will damage the parts of the engine cooling system, resulting in unexpected consequences and economic losses.
In order to ensure the safety of coolant use, the engine cooling system must be cleaned before filling the coolant, and appropriate coolant must be added.
Usually, we need to change the coolant for the engine every two years. We know that the coolant itself is a chemical raw material, which can prevent boiling, freezing, rust and corrosion within the validity period. However, once the coolant deteriorates, acid will corrode the engine and cause embroidery. It is very difficult to clean the acid and deteriorated coolant in the engine water tank if only changing the coolant.
