The radiator in a car has a very important function. If the radiator is damaged, it can be assured that the car's performance will be suboptimal. Even if the damage worsens, it could potentially damage other components of the car.

One of the damages that can occur is a leaking car radiator. Such leaks can happen for various reasons. Usually, radiators are made of aluminum, which makes them susceptible to leaks due to cracks or tears.

Leaking Car Radiator? It's Better to Replace It with a New One

The function of the car radiator is as a cooling system for the engine. A running car will make the engine work and can increase its temperature. If there is no radiator, the car engine can experience overheating. A condition where the car engine has a high temperature.

The presence of radiator water is useful for absorbing heat from the engine. Later, when the radiator water gets hot, it will flow to the radiator. Then it is cooled again before being sent back to the car engine. However, if the car radiator is leaking, the radiator water will decrease, and the engine may lack coolant.

This is what causes the engine to overheat. Generally, leaks in the radiator occur at the upper or lower tank and the mesh pathways in the radiator water. If such a leak occurs, you will usually be confused about whether to replace the radiator with a new one or just repair it.

A cheaper alternative to address radiator leaks is to carry out repairs. However, you should know that the process of repairing a leaking radiator may not last long. It could even worsen the damage.

This situation can occur if your car radiator is repaired by someone inexperienced. This can happen because repairing a leaking radiator is done by welding. If welded, it is possible that leaks will occur in nearby areas.

In addition, the difference in aluminum materials can also be a cause. When welding, the material may not bond perfectly. Such conditions can worsen radiator damage. You will definitely incur losses by having to spend money again to repair it.

To repair a radiator, it indeed needs to be patched, which can cause the mesh pathways to become blocked. It would be better if you directly replace the radiator with a new one. A new radiator can certainly work optimally, and the car engine will no longer experience overheating.

Replacing the radiator with a new one does require a certain cost and is more expensive than repairing the radiator. However, it is much better to spend a significant amount to get a new radiator that is more durable.

Once you have replaced the radiator with a new one, it should be well maintained to avoid leaks again. To maintain your radiator, it is advisable to regularly change the radiator water every 20,000 km.

Regularly changing the radiator water can keep the tank clean and free from rust. One of the causes of a leaking car radiator is rust. Therefore, take good care of the radiator so that such leakage cases do not occur to you again.

Don't forget to have regular service at the nearest Daihatsu dealer. Also, get interesting and updated information about other automotive topics through the Daihatsu.co.id website.
