How to Deal with Rust in the Radiator?

[DelBlakely]

Here are the methods to deal with rust in the radiator: 1. For newly manufactured cars: Newly manufactured cars come with antifreeze added at the factory, and there is no air inside the radiator, so there is no rust in the car radiator. 2. If there is water in the radiator: Even if water is added to the radiator, there should be no rust because the oxidation of iron requires oxygen. When the radiator is full of water, there is no air, hence no oxidation. 3. If cold water is added to the radiator: Over time, scale (calcium carbonate) may form in the radiator when cold water is added. This can react chemically with acid and be removed, so it is necessary to soak it with more vinegar. Since a brush cannot be used inside the radiator, a longer soaking time is required. 4. If there is a small amount of rust in the radiator: If there is indeed a small amount of rust in the radiator, it can also be soaked in vinegar and then rinsed. The main component of rust is iron oxide (Fe2O3), which reacts chemically with vinegar to remove the rust.
