How long to clean the engine cooling system
Expert advice: At present, the engine cooling system, although most of the use of antifreeze, rust and descaling capacity of the antifreeze, but after a long period of use, due to chemical changes between substances, the performance of non-frozen liquid will gradually decline , The cooling system after a long period of use will appear in these three cases: First, the coolant salt in the system wall deposition to form a large number of scale, thus affecting the cooling system cooling capacity, resulting in water tank boil, the engine overheating, Power consumption and fuel consumption increased, etc. Second, the coolant and metal electrolysis and chemical reactions, so that the metal surface corrosion, the phenomenon of "cavitation", resulting in crankshaft, piston and piston ring early wear; When the coolant contains silicate, when the coolant temperature from high to low changes, the silicate will produce "differentiation" phenomenon, in the coolant to form a moss of the stripes, reducing the cooling fluid flow rate , The cooling function of the cooling system is reduced.
Consumer reminder: When the car driving a certain mileage, should be combined with the maintenance of the cooling system to remove the scale of a
Cooling system of the demolition of care products according to their different functions can be divided into three kinds: cleaning agents, protective agents and anti-leakage agent. Radiator cleaning agent can effectively remove the grease, glial layer and radiator, cylinder liner and scale and corrosion in the cooling system, and restore the cooling capacity of the system to solve the problem of overheating and radiator caused by excessive scale And other issues. Protection agent to strengthen the antifreeze antirust, anti-corrosion function, can effectively prevent the cooling system of metal parts rust and corrosion. It can also be compatible with all types of antifreeze coolant. Throttle agent can quickly stop the leakage of various parts of the cooling system to stop and prevent the damage caused by the cylinder pad damage caused by frost coolant, lubrication pump, water jacket, direct use will not block the cooling pipe. As with the protective agent, it is also compatible with all types of antifreeze coolant.
