How to Clean Scale in the Engine?
2 Answers
Engine scale can be cleaned by following these steps: 1. Turn off the engine at normal operating temperature, immediately drain the coolant, and add cleaning agent to the cooling system; 2. Start the engine and maintain medium-speed operation for 5 to 10 minutes. During this period, change the speed several times to alter the flow rate of the cleaning agent and flush out deposits in the system. Then, turn off the engine and let it sit for about 10 hours; 3. Restart the engine, run at medium speed for 5 to 10 minutes, then turn it off and drain the cleaning agent while it's still hot; 4. Replace with clean water and continue flushing about two more times until the drained water shows no dirt. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, and electric motors.
My old car had the same issue last year, with white scale deposits clogging the engine and the temperature gauge climbing rapidly. DIY cleaning isn’t actually difficult—the key is choosing the right cleaner. Last time, I used a citric acid-based engine descaler: first, drain the coolant completely, mix the descaler with water according to the instructions, pour it into the radiator, then idle the engine for half an hour to let the solution circulate. Finally, flush it thoroughly with clean water three times. Keep a close eye on the temperature gauge throughout the process—if the needle hits the red zone, shut off the engine immediately. After cleaning, replacing the antifreeze is crucial, or all the effort goes to waste. Remember to check the radiator seasonally to prevent scale buildup.
