2011-2018 6.7L Ford Powerstroke AC Expansion Valve
Expansion Valves are an important part of the A/C system. The expansion valve is a metering devise that controls the flow of Freon entering the evaporator. It also regulates the flow of Freon to match the thermal load. When a compressor fails, it is common for contaminants to get into the expansion valve causing it to clog up or stick open. Anytime a compressor is replaced it is recommended to replace the compressor, accumulator / drier, and the expansion valve.
