Radiator Flush, as the name itself suggests is a process in which the radiator is flushed to remove, the debris, contaminants, dirt, etc. in the radiator.

What is the need for a radiator flush?

The answer to this question is not very simple, to know the need for a radiator flush. You should first need the importance of radiator and coolant. A radiator without coolant is worthless and it could kill the engine in the long run. The purpose of coolant is to cool the engine and to keep the engine at an optimum temperature. This is done by circulating coolant through the engine continuously. However, with time, coolant could become inefficient as it gets mixed with debris and contaminants. These contaminants and debris could boost corrosion, scaling, and blocking of the cooling system. Most people believe that changing coolant could fix this issue, this is not true. Even if the coolant is drained, the debris, contaminants, and scales could remain in the radiator. Only quality radiator flush could remove these contaminants, debris, and scales.

A radiator flush is a process of removing rust, contaminants, scales, and debris from the radiator to make it function more efficiently and to increase the lifespan. Therefore, commonly, dedicated radiator flush fluids or cleaners are used to flush the radiator, some people use water to do the radiator cleaning. However, using a combination of radiator flush fluid/cleaner and distilled water is the best way to flush the radiator efficiently.

Apart from the radiator cleaner and distilled water combination, some people recommend vinegar. However, we will not recommend that you use vinegar. Even if you plan on using vinegar, it will not be very efficient. Remember, vinegar is a mild acid that could have some cleaning benefits. Apart from this, there might be some homemade radiator flush fluids that could be used.

Using tap water for radiator flush is highly discouraged while using tap water might be an economical way of doing it, it could destroy your radiator. Remember, tap water might have several types of minerals in it, which might be left in the radiator. This would kill the radiator and the engine. If you want the radiator flush to be efficient, then it is best recommended to use dedicated radiator flush fluid.
