Komponen Radiator Mobil: Fungsi dan Tips Perawatannya

Car radiator components are among the components that play an important role in the car's cooling system. Although they are considered important, not all car owners understand the function and how to maintain these components. In fact, if these components are damaged, it can have fatal consequences for the car. To prevent this situation, let's take a look at the following review.

A Brief Overview of Car Radiator Components

As explained above, the car radiator is a car component that acts as the engine cooling system. With this component, the engine temperature will remain stable. The car radiator can be referred to as a tool for transferring heat from one medium to another so that the hot engine condition can be cooled. 

To optimize the performance of the car radiator, this component is supported by other components within it. Here are the complete supporting components.

1. Radiator cap

The radiator cap is a radiator component that functions as a cover for the radiator opening, a coolant filling container, and a radiator pressure controller.

2. Lower tank

This component is located at the bottom of the radiator and functions as a reservoir for coolant after the cooling process. The coolant that enters this component will later be channeled to the passages surrounding the car engine to absorb the engine's heat. 

3. Upper tank

The upper tank or reservoir tank is the component located right above the car radiator. This component functions to hold coolant that carries heat from the engine area.

4. Radiator hose

This component connects the engine block with the radiator. The radiator hose itself is divided into two types, namely the upper hose and the lower hose. The upper hose functions to channel hot coolant that absorbs the engine's heat to the radiator. Meanwhile, the lower hose functions to channel coolant from the radiator to the engine.

5. Radiator core

The radiator core is a component that functions as a heat distributor from the coolant that has passed through the engine's exit port. 

6. Radiator fan

This component functions to optimize the performance of the radiator core to release the heat from the outgoing coolant.

7. Drain plus

Drain plus is a component that functions to drain the coolant located beneath the radiator. 

Functions of Radiator Components

From the components above, it can be concluded that the radiator components have the function of cooling the car to prevent overheating (excessive temperature increase). As is known, overheating can cause damage to the system and other car components, even leading to the car catching fire.

Proper Maintenance Tips for Car Radiator Components

To ensure that the radiator components in the car can work optimally and are not easily damaged, proper maintenance is required as follows.

1. Regularly check the fluid volume in the radiator tank

To keep the car radiator components durable, you need to pay attention to the fluid volume in the radiator tank. Make sure to always refill the coolant if the fluid volume decreases.

2. Regularly clean the radiator tank

In addition to monitoring the fluid volume in the car radiator tank, you also need to clean the tank regularly. Make sure to clean it at least every two weeks. Don't forget to also clean the cover, hose clamps, cooling fan, and oil pump.

3. Use the right fluid

Next tip, use coolant specifically designed for car engines to prevent the radiator tank from corroding or becoming clogged with dirt. 

4. Ensure the radiator is tightly closed

Next, you need to ensure that the car radiator opening is tightly closed to prevent coolant leaks.

5. Do not overload the car beyond its capacity

Lastly, you need to ensure your car's load. Make sure the load does not exceed the car's capacity. Because, excessive weight can burden the performance of the engine and car radiator, making the car prone to overheating.

These are the proper tips for maintaining your car radiator. Don't forget to service your car at a Daihatsu workshop regularly and periodically to ensure all components of your car are in optimal condition.
