In a car, the radiator plays an important role as a temperature stabilizing unit inside it. This is why this part must always be maintained and cleaned. Cleaning the car radiator is also not too difficult. 

If you perform regular cleaning, the dirt that needs to be cleaned will not be too much. Thus, the cleaning time will also be relatively short. And if you want to know the function and how to clean the car radiator, make sure to read our article below. 

Here is the Function of the Radiator in a Car 

A quality car like those produced by Daihatsu must have a cooling unit inside it. And the radiator is one of the components in the car's cooling or AC unit. 

Thus, the radiator has the function of stabilizing the temperature inside the vehicle. Without a radiator, a car can experience overheat due to continuously burning fuel to move on the road. 

The way a car radiator works is by channeling hot temperatures from the car to the open air. In addition, the radiator also functions to circulate coolant from its tank to various channels inside the car. 

As a result, the hot temperature inside the car can be absorbed and will be expelled into the air. Consequently, the interior of the car can be perfectly cooled by the car's AC freon unit. 

Practical and Easy Ways to Clean a Car Radiator 

The radiator unit in the car must always be cleaned because if not, it can disrupt the performance of the car's cooling system. Here are practical and easy ways to clean the car radiator that you can do yourself: 

Prepare tools and cool the engine 

When you are going to clean the radiator, make sure to prepare the necessary tools. For example, car cleaning tools and new coolant fluid. Don't forget to cool the car engine before cleaning the radiator part. 

Drain the previous radiator fluid 

The next step is to ensure that you completely drain the fluid in the radiator beforehand. The way to do this is by opening the radiator valve located under the tank, allowing the fluid to drain out completely. Make sure there is no radiator fluid left in the tank before you clean that part. 

Clean the core tank 

Next, make sure to clean the core tank part of the radiator. This component is the core part of the radiator responsible for stabilizing the temperature inside the vehicle. Make sure to use the best coolant fluid for this process. After that, try to start the engine until it heats up for about 15 minutes. 

Check the radiator 

When heating the engine, ensure that the water in the radiator tank is completely drained. Thus, when all the radiator water is gone, the radiator should be refilled with new fluid. Make sure that the radiator fan is always on as a sign that the part is completely clean. 

Reassemble the disassembled car parts

As a final step, you need to reassemble the disassembled car parts. Make sure to install the various parts that were removed to clean the car radiator. 

By following the steps above, your car radiator will surely last and be durable. So, make sure to regularly clean the car radiator to avoid damage in the future.
