Car radiator cleaning method is: 1. Before cleaning, remove the bumper. Ensure all fixing screws are unscrewed during removal, then slowly detach it from both ends towards the center, being careful not to break any fixing clips; 2. After removing the bumper, the radiator's position will be visible. Adjust the water gun nozzle to a spray pattern and set the pressure to an appropriate level, then rinse the dirty radiator surface; 3. Once rinsing is complete, check if any radiator fins are bent or damaged. If found, use tweezers or bamboo sticks to straighten them. After all checks, reinstall the bumper in the reverse order of removal to complete the radiator cleaning process.
I often clean my car's radiator by myself, and the method is quite simple. First, turn off and cool the engine to avoid burning your hands. Then, use a hose connected to tap water to rinse the exterior of the radiator, removing surface dust and insect debris. Be careful not to use too strong a water flow to avoid bending the radiator fins. Next, deal with internal dirt by pouring a specialized radiator cleaner into the coolant system, letting the engine run for 10 minutes before turning it off and flushing out the contaminants. After cleaning, check for any leaks to ensure everything is normal. This helps prevent radiator blockages, extends its lifespan, and avoids engine overheating and major repairs. It’s recommended to clean it every six months.
