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.
When cleaning the exterior of the car radiator, I find this method the most practical. First, let the engine cool completely for at least an hour to avoid burning your hands. Then, mix a bucket of warm water with a small spoonful of mild detergent and stir well. Use a soft-bristle brush or an old toothbrush to gently scrub the radiator surface. Pay special attention to brushing along the direction of the fins without applying too much force, as bending them can affect cooling efficiency. After washing, rinse thoroughly with a hose set to low water pressure—never use a high-pressure washer, as it can damage components. I do this monthly to prevent clogging from insect remains and dust, which improves cooling, reduces engine noise, and saves fuel. Wearing gloves and goggles during cleaning ensures safety. After finishing, drive for a few minutes to check the cooling system and ensure everything works properly.
DIY radiator cleaning is so much fun! I often use eco-friendly methods like mixing white vinegar and water in a spray bottle, spraying it on and waiting a few minutes for dirt to break down. For tools, I choose soft sponges or wool brushes to gently wipe up and down without rough handling—radiator surfaces often have dust in crevices that require patient thorough cleaning. After cleaning, I immediately rinse gently with a garden hose. It's more cost-effective and environmentally friendly than chemical cleaners. I also take the opportunity to check for cracks or rust around the radiator—regular cleaning extends its lifespan and prevents overheating issues. Doing this while chatting with friends turns it into an enjoyable activity.
Experience has taught me that cleaning the radiator requires careful step-by-step attention. After confirming the engine has cooled down completely, prepare warm soapy water and use a soft cloth to gently wipe every corner. When rinsing, adjust the water flow to a fine drizzle to meticulously wash away the foam—avoid strong jets. This method prevents the radiator fins from deforming, maintains cooling efficiency, and avoids potential leaks. After cleaning, take some time to inspect the radiator's condition to ensure everything is in good order.
