The method for cleaning a sedan's 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 port; 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 car radiator: Absorbs heat from the engine block to prevent engine overheating and malfunctions. Precautions for using a car radiator: 1. Prevent the radiator from overheating; 2. Regularly replace the coolant; 3. Do not use tap water as a substitute for coolant; 4. Choose high-quality diluted water or antifreeze when selecting radiator fluid; 5. Perform regular anti-rust treatment on the radiator; 6. Address radiator malfunctions promptly to avoid further damage from continued use.
Cleaning a car radiator, I have some personal experience to share. First, wait for the engine to cool completely—for safety, wait at least an hour or until it’s no longer hot to the touch. Locate the drain valve at the bottom of the radiator, then slowly loosen it with a small wrench to drain the old coolant, using a pan to catch it and prevent contamination. Flushing is key: I connected a garden hose to the flush port and cycled clean water through the system three times, stopping only when the water ran clear instead of cloudy—this removes rust and sediment buildup. After flushing, close the valve and refill with fresh coolant to the marked level. Start the engine for a few minutes to purge air bubbles, while checking hoses and connections for leaks. Annual cleaning is recommended to prevent clogs that cause engine overheating and extend component life. Simple tools are all you need—proper maintenance saves hassle and potential repair costs.
