The best method to remove rust from a car radiator is to use a professional car radiator descaler. The steps are as follows: 1. Directly pour the dedicated scale remover into the car's water circulation system. 2. Let it soak, idle cycle, or drive for 20-30 minutes. 3. Drain the descaler from the radiator and the internal system. 4. Rinse repeatedly with water to effectively remove scale, rust, mud, and various harmful substances from the car radiator. Additional information: 1. The radiator is part of the car's cooling system: The radiator in the car's cooling system consists of three parts: the inlet chamber, the outlet chamber, the main plate, and the radiator core. 2. There are two main materials for radiators: aluminum and copper. The former is used for general passenger vehicles, while the latter is used for large commercial vehicles.
I've been driving an old car for over a decade, and rusty radiators are quite common. The best method is to use a specialized scale cleaner—first, buy a reliable brand from the shop, pour it into the radiator, then start the engine and let it run for about ten minutes. The cleaner will dissolve the rust. After draining the dirty water, flush the radiator thoroughly with clean water two or three times to ensure no residue remains. Using distilled water for flushing is recommended, as regular tap water contains minerals that can cause rust to form again. Once cleaned, fill the radiator with antifreeze, which contains rust inhibitors, and the engine temperature will stabilize. Excessive rust buildup can cause the engine to overheat and fail, so regular maintenance is crucial—replace the antifreeze every two years to prevent issues. Keep an eye on the coolant color; if it becomes cloudy, clean it early—don’t delay. The whole process is straightforward and saves money if done yourself, but wear gloves for safety.
