GMC Savana Van A/C Expansion Device

The air conditioning system includes many major components like compressor, condenser, evaporator, accumulator-drier, expansion device etc. Among these, one of the important components which help in controlling the cooling effects inside the passenger cabin is the AC expansion device. The AC expansion device helps to vary the flow of refrigerant based on the cooling requirement. When you require more cooling effect, the valve opens more than the normal opening to allow more flow of refrigerant to the evaporator and when the cooling effect is reduced, the opening of the valve contracts, reducing the flow of refrigerant.

The AC expansion device consists of three point’s evaporator, bulb and the spring. The pressure is controlled at these three points. It is connected to the sensor bulb to monitor the cooling effect. If the bulb pressure is increased, it opens the valve and more refrigerant flows. In either way, it reduces the refrigerant flow. When your GMC Savana Van A/C expansion device is not functioning properly, you can feel the difference in the cooling effect of your AC system. That is the right time to look for either repair or replacement of AC expansion device. At Car Parts Warehouse we have a variety of car parts.
