How often should the exterior of a car radiator be cleaned?

[StAdelyn]

It is recommended to clean the exterior of the car radiator every six months. This is because the radiator contains antifreeze, which prevents the cooling system from freezing in low temperatures and boiling in high temperatures. However, during use, the antifreeze can accumulate impurities and sediment, leading to scaling that affects heat dissipation efficiency. Therefore, regular cleaning is necessary. The cleaning methods are as follows: 1. For the exterior, use a high-pressure air pump to blow out impurities from the gaps rather than rinsing with water; 2. For the interior, use chemical methods to remove scale. Professional car radiator descaler can clean the interior without disassembly and can even be used while the car is running; 3. Follow the instruction manual carefully. You can pour a specialized descaling agent into the car's water circulation system, let it soak, idle, or drive for 20 to 30 minutes, and then drain the descaler from the radiator and system.
