The cooling system in your vehicle is responsible for regulating the engine's temperature, ensuring it operates within the optimal range. It consists of various components, such as the radiator, water pump, thermostat, and coolant hoses, all working together to circulate coolant and dissipate heat. When air enters the cooling system, it can disrupt the proper functioning of these components and lead to a host of problems.
