What are the good methods for cleaning the radiator?

Here are the methods for cleaning the radiator: 1. Manual cleaning method. The car radiator needs to be removed and cleaned manually with tools like hammers, scrapers, and shovels to remove scale; the descaling efficiency is low, the labor intensity is high, it is not easy to clean thoroughly, and it may cause secondary damage to the radiator. 2. Ordinary scale cleaner. The radiator needs to be removed, but the cleaning is not thorough, it has a strong odor and high corrosiveness, which can easily cause the radiator to age and shorten its service life. 3. Professional car radiator descaler. It can clean without disassembly and can even be used while the car is running. Simply pour the specialized scale cleaner into the car's water circulation system, let it soak, idle, or drive for 20-30 minutes, then drain the descaler from the radiator and the system, and rinse repeatedly with water. This can effectively remove scale, rust, sludge, and various harmful substances from the engine's water circulation system.
I've got some experience with radiator cleaning. First, drain the old coolant from the cooling system, then prepare a set of flushing tools like professional cleaner and hoses. Flush with water several times until the outflow runs clear. For severe internal deposits, partial disassembly for cleaning might be needed, but be careful not to damage the cooling fins. After flushing, always refill with fresh coolant at the correct mixture ratio to prevent engine overheating and corrosion. The whole process takes about half an hour - the key is using gentle pressure to avoid pipe bursts. Cleaning every two years significantly improves cooling efficiency, reduces engine failure risks, and makes driving smoother and more fuel-efficient. DIY saves money, but safety precautions are essential.
