What is the method for cleaning the engine radiator?

Cleaning the engine radiator involves the following steps: 1. Park the vehicle and turn off the engine. Wait for the coolant temperature to drop, then open the expansion tank and add radiator cleaner. 2. Start the engine and let it idle for 5 to 10 minutes after the cooling fan activates. 3. Turn off the engine and remove the front bumper. Ensure all mounting screws are loosened before gently detaching it from both ends toward the center, being careful not to break any retaining clips. 4. Once the coolant has completely cooled, drain the radiator cleaner along with the old coolant, then refill with fresh engine coolant.
I've been thinking about cleaning the engine radiator for a long time. Generally, it can be done in five steps: First, wait until the engine is completely cooled to avoid burns from operating on a hot engine; then, open the drain valve at the bottom of the radiator to drain the old coolant completely, remembering to use a basin to catch it and avoid environmental pollution; next, pour in a professional radiator cleaner, mix it with water according to the instructions, and fill it up, then start the engine and let it idle for 10 minutes to circulate the cleaner; after turning off the engine and letting it cool, drain the dirty water, then rinse repeatedly with clean water two or three times until the water runs clear; finally, replace it with new coolant, paying attention to bleeding the air and checking the fluid level. Remember to clean it once a year before summer, especially for cars that frequently travel long distances. Too much scale can lead to poor heat dissipation, causing the engine to overheat and stall.
