One of the most common but serious problems that develop in the cooling system is a leak in the radiator. A crack or leak in the radiator can result in a significant loss of coolant or antifreeze. Without the presence of these fluids in the cooling system, air bubbles begin to form. The most common cooling system problems fall into three common areas, such as overcooling, high temperatures, and noise.
The fourth problem is the internal overheating of the engine. This is seen as burned out valves or worn pistons or rings, caused by overheating of the internal parts. Overheating is one of the main problems of the cooling system. It is due to the insufficient amount of water in the cooling system and the loss of coolant.
Overheating is due to factors external to the cooling system. An engine is said to be supercooled if it is operating below the normal operating range. This problem usually appears in winter because the heater does not work. Overcooling is due to a thermostat that opens too soon or stays open at all times.
Noises can occur in the cooling system due to the dry bearing, a loose pulley on the pump shaft, a loose impeller on the shaft, or two ends of the shaft. Some pumps require the addition of a special lubricant for water pumps to the coolant, making operation quiet. Preventive maintenance can be very useful for your cooling system and ensure that you use your vehicle for longer. When your car has a cooling system problem, your top priority should be to fix it quickly, as engine repairs and major rebuilds cost drivers thousands of dollars a year.
It contains added substances that prevent the cooling system from freezing, lowers the boiling point and helps to coat and fix the cooling system.
