How to Deal with Rust in the Radiator?

[McRiley]

Pour a specialized scale remover directly into the car's water circulation system, allowing it to soak and idle circulate. Wait for twenty to thirty minutes, then drain the descaling agent from the radiator and the system, and rinse thoroughly with water repeatedly.

I've dealt with car radiator rust several times myself and found it not too difficult. The first step is to park and check the rust level: open the radiator cap to inspect the interior; if it's just minor rust, use household white vinegar mixed with water, pour it in and let it soak for three to four hours, then slowly drain and flush the entire system clean. After that, add new coolant along with some rust inhibitor to prevent new rust formation. This method saves time and money, but make sure the engine is completely cool to avoid burns. By the way, using distilled water instead of regular tap water in daily use can reduce rust buildup, and changing the coolant every six months keeps the system lubricated and running smoothly. Long-term neglect can easily lead to engine overheating and breakdowns. Addressing it early is much better than scrambling at the last minute. Anyway, the fun lies in the hands-on process.
