Cleaning the engine radiator involves the following steps: 1. Remove the bumper; 2. Adjust the water gun nozzle to a spray pattern and set the pressure to an appropriate level, then spray towards the dirty radiator; 3. Add the car radiator cleaner into the radiator filler port, let it soak for thirty minutes, then drain the cleaner and rinse the radiator and pipes thoroughly with water. The function of the engine radiator is: when the engine's water temperature is high, the water pump circulates repeatedly 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 temperature from dropping.
The method I use to clean the engine radiator starts with parking and cooling. First, let the engine cool down for at least half an hour before carefully opening the radiator cap to avoid burning your hands. Drain the old coolant into a container—it's environmentally harmful and must be disposed of properly, not poured randomly. Next, pour in a radiator-specific cleaner, available at supermarkets or auto shops for about ten yuan a bottle, then fill it with distilled or purified water. Start the car and let it run for 10-15 minutes to allow the cleaner to circulate and dissolve scale and sediment. After that, turn off the engine, drain the dirty water, and rinse the radiator several times with a soft hose until the water runs clear. Finally, refill with a 50% mix of new coolant and water, ensuring the level reaches the standard mark. Remember, neglecting this can lead to a clogged radiator, causing the engine to overheat and stall. I usually clean it once a year to save money and hassle. If the radiator shows severe rust, it's best to have a professional check the fan and cooling fins early on.
