Regularly Perform a Radiator Flush

For your radiator to do its work effectively, it needs to be free from any dirt or blockage. You can make sure your radiator is clean by doing a radiator flush.

This is wrong. If you need to flush your radiator regularly because of debris, it means that your cooling loop is heavily corroded and suffers from severe cavitation. This after all is the source of blockage and debris.

Cooling systems by design are sealed systems, they should not leak, generate precipitate, or produce debris. If this is occurring your engine is practically being eaten inside out.

Ultimately this means that the coolant mixture employed doesn't have the necessary corrosion and cavitation inhibitors.

Corrosion in simple terms is kalawang.

Cavitation in an engine is caused by high pressure impact of the coolant on a metal surface. Think about it like microscopic hammers banging on the walls of the water channels causing particles to chip off across time. This is bad as it lowers your engine's lifetime.
