It may be required to repair the engine cooling system in the event of its failure, which is evidenced by such signs as engine overheating or overcooling and coolant leakage. The system failures are most often caused by the use of components of the system parts (pipes, radiator and others), the use of poor-quality coolant, wear of the elements of the car's cooling system, poor-quality maintenance and repairs, clogging of cooling devices. Repair of the engine cooling system is carried out by eliminating breakdowns of system elements or their complete replacement.
