The method for cleaning foreign objects on the radiator is: 1. Start the vehicle and let it reach normal operating temperature; 2. Slowly open the radiator cap, shake the rf12p well and add it through the radiator filler opening; 3. Let the engine idle for no less than 15 minutes, drain the coolant, and flush the radiator with water until clean water flows out. The function of the radiator: Absorb heat from the engine block to prevent engine overheating and malfunctions. Precautions for radiator use: 1. Prevent the car radiator from overheating; 2. Replace the coolant regularly; 3. Do not use tap water as a substitute for coolant; 4. Choose high-quality diluted water when selecting radiator fluid or antifreeze; 5. Perform regular anti-rust treatment on the radiator; 6. Address radiator malfunctions promptly to avoid causing other issues with continued use.
When there are foreign objects on the radiator, I always make sure the engine has cooled down before handling it to prevent burns. Usually, the debris consists of leaves, dust, or insect remains. First, I use a soft-bristle brush to gently remove loose particles, avoiding hard objects that could scratch the fins. Then, I rinse with a low-pressure water spray, sweeping the nozzle in one direction from the inside out—never spraying directly to prevent fin deformation. For stubborn dirt, I use a neutral detergent for wiping but avoid harsh chemical cleaners. After cleaning, I check for unobstructed airflow and feel the surface to ensure proper heat dissipation. I adhere to a quarterly cleaning routine because accumulated debris reduces cooling efficiency and increases the risk of engine overheating. Always remember to wear gloves and goggles for safety. Once, delayed cleaning caused my engine temperature to spike, nearly leaving me stranded on the highway. Now, I remind friends to maintain their radiators regularly, especially before summer road trips—good habits save big repair costs.
