The car radiator is responsible for preventing overheating of the car engine. When the engine is in use, it creates a lot of friction and heat, and the radiator uses coolant to maintain normal engine operation.
The radiator is connected to the engine by channels through which fluid is pumped. This fluid may be water or another coolant, such as antifreeze. By passing fluid through the engine, it heats the fluid and moves it outside the engine to allow it to cool. It is usually located in front of the grille of the vehicle in order to use the air flow when driving the car.
If there is not enough coolant, the engine may overheat. It is important to monitor the level of the coolant, and instead of opening the radiator cap to check, the coolant reservoir should be looked under the hood. If the fluid does not reach the line marked as “full,” coolant should be poured until it reaches the line. Some coolants are premixed, others are concentrated. If it is a concentrate, prepare a mixture of 50% coolant and 50% water or follow the directions on the bottle. Never add coolant while the engine is hot, as this may damage the engine. If there are bits in the coolant, the system must be flushed. A sluggish or oily surface is an indicator of a possible leakage of the cylinder head gasket.
