Diesel engine cooling system cleaning method

If the diesel engine is used for a long time, it will inevitably generate a large amount of mineral deposits, ie, scale, which will seriously affect the cooling effect of the machine, resulting in diesel engine temperature is too high, so that the working conditions of the various parts deteriorate, wear and tear, power decline, It even led to such vicious accidents as "sticky cylinders", "burning tiles", and "pivoting axes." Then, how can we thoroughly clean the cooling system? The method is as follows:
(1) Start the engine, run at medium speed, turn off the water when the water temperature rises above 50°C, and drain the cooling water.
(2) Inject the cleaning fluid formulated with 20 kg of water plus 1.5 kg of caustic soda and 0.5 kg of kerosene into the tank.
(3) Start the engine. After 5-10 minutes of medium speed operation, stop for 10 hours.
(4) Start the engine again, control the throttle so that the speed is fast and slow, let it vibrate and generate a shock wave of water, so that the scale or sediment suspended. After 5-10 minutes of operation, clean the cleaning solution.
(5) Add clean, soft water to the water tank, then start the engine, and drain the washing water after running for 5 minutes at moderate speed. Repeat this cleaning 2-3 times.
