It is possible to damage the radiator for cooling the engine of a car at a time: a small blow, a tree branch that has fallen into the honeycomb, or some other minor breakdown can damage it. Time also does not make the item newer. And small cracks and constant vibrations from the engine do their job.
To repair the engine cooling radiator on their own, manufacturers came up with a fairly large number of polymers that are quite effective, but such repairs can not be called capital and long-term. However, without an acetylene burner, aluminum solder and the ability to use all of this, such a radiator cannot be repaired, therefore, living away from good service centers, it is better to buy a cooling radiator from trusted and reliable manufacturers.
A defective engine cooling radiator entails overheating and, as a consequence, death, which is why it is so important to monitor its stable operation and prevent the vehicle from moving in case of damage. It should also be remembered that a defective cooling radiator must be replaced with a new one, and not try to repair it.
As such, repair of the engine cooling radiator is not carried out and is not advisable, therefore, the desire to save money in this case is inappropriate and will lead to even greater costs.
