What is the method for cleaning the exterior of a car radiator?

[LaSamuel]

The method for cleaning the exterior of a car radiator 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 car radiator is: when the engine's water temperature is high, the water pump repeatedly circulates to lower the engine's temperature, thereby protecting the engine. In winter, when the water temperature is low, the water circulation stops to prevent the engine from cooling down. The components of a car radiator include: 1. Radiator core; 2. Water pipes; 3. Cooling air fins; 4. Upper water tank; 5. Lower water tank.
