In the reinstallation phase follow a reverse procedure while using both new gasket and O-ring seals along with adding proper PAG oil amount to the refrigerant system. Finish up the process by filling the engine coolant level followed by evacuating and leak testing the refrigerant system before charging it with refrigerant.
