How to Clean Scale Inside the Engine?

[DiJoy]

Engine internal scale cleaning method is as follows: 1. After the engine is turned off, drain the cooling water and add cleaning agent; 2. Start the engine and run at medium speed for 5-10 minutes, then let it sit for 15 minutes; 3. Run at medium speed again for 5 minutes, then drain the cleaning agent. Repeat this process three to four times until the discharged cleaning agent is free of contaminants. More information about engine scale: 1. There are two commonly used cleaning agents for removing scale: one is adding 750g of caustic soda and 250g of kerosene to 5000g of water; the other is adding 1000g of baking soda and 500g of kerosene to 5000g of water. The amount of cleaning agent should be determined based on the volume of cooling water. 2. Excessive cooling water temperature caused by scale will also lead to high temperatures in the cylinders and intake passages, causing the mixed gas entering the cylinders to expand due to heat, reducing air intake, lowering engine power, increasing fuel consumption, and potentially causing "auto-ignition" or "knocking" phenomena.
