It is important to periodically check and bleed the coolant system, to ensure proper cooling and help prevent any damage to the engine due to overheating. Too much trapped air causes water to circulate inefficiently in the home, resulting in cold spots and inefficient heating. A compressor is a device that sucks in air and blows it out the back of your radiator. Generally, these valves vent pressure or release media from within a system.
