Scrub the water deposit off
Scrub the water deposit off the coolant tank wall and the water jacket with cleaning
liquid in time, in order to ensure cooling effectiveness and avoid overheating of the
diesel engine.
Generally, the cleaning liquid is appropriated as follows: add 750~800g sodium hydroxide
and 150g kerosene per 10-liter water and mix the three evenly.
Cleaning procedures: Drain the water coolant in the water tank and add the cleaning
liquid into the tank. Run the diesel engine with cleaning liquid as coolant water in
medium speed about 10~15 minutes, warming up cleaning liquid. Let the cleaning liquid
remain in the tank for about 12~15 hours and run the engine again in medium speed
about 10~15 minutes. Then, discharge all of the cleaning liquid and add water into the
tank. Again, run the engine in medium speed for some time and drain the water. At this
time, the cleaning is completed. If the water deposit is serious, repeat the procedure
aforementioned 2~3 times.
Note: Sodium hydroxide is strongly basic. Do not eat or touch it. If your skin contacts it,
please rinse you skin immediately with water.
