What is the method for cleaning an engine radiator?

Engine radiator cleaning method is: 1. Remove the bumper; 2. Adjust the water gun nozzle to a spray pattern and set the pressure to an appropriate level, then rinse the dirty radiator surface. The function of the engine radiator is: when the engine water temperature is high, the water in the water pump circulates repeatedly to lower the engine temperature, thereby protecting the engine. In winter when the water temperature is low, the water circulation stops to prevent the engine temperature from dropping. The components of an engine radiator include: 1. Radiator core; 2. Water pipes; 3. Cooling air fins; 4. Upper water tank; 5. Lower water tank.
I've washed my car's radiator several times myself and found it quite useful. The key is to wait until the engine is completely cooled down before starting the operation, otherwise, burns can be dangerous. First, open the drain valve at the bottom of the radiator to let all the old coolant out. If the valve is dirty, wipe it with a cloth first. Then, add a specialized cooling system cleaner, such as those liquids that can remove rust, pouring in the amount according to the instructions on the bottle. Start the car and let it run for about 10 to 15 minutes to circulate the cleaner throughout the system. During this process, be careful not to let the water temperature get too high, and keep the hood open for ventilation. After draining the cleaning solution, rinse the radiator with clean water two or three times to ensure it's clean and residue-free. Finally, add a new coolant mixture, preferably a half-coolant, half-distilled water blend, and check for any leaks. Regularly cleaning the radiator can prevent engine overheating and extend its lifespan. My car has been running for five years without any major issues.
