Beware. It's 134a not Freon. There are product on the market, both for genuine 134a and what they call "Freon Replacement" for old cars, Freon R-12 is not available for the public to purchase Just read labels carefully

Thank you, one more question, is there an expansion valve in this system?
Yes, There has to be, The laws of physics say expanding gas gets cold. The compressor pushes the gas in to the condenser, in the front of the car, the heat is dissipated there then out to the expansion valve to get cold and in to evaporator in cabin to expand even more and air flows over it. I will show you a diagram, will take a minute to find
I forgot about the drier. Anyway, you can't hook it up backwards, people used to hook the new can on the hifg pressure port and the compressor would pump IN to the can and blow up. Now the ports are different, the high pressure line is bigger than the low and has a different fitting.
That image is generic, now this is Ford, (2) is expansion valve
To clarify, while in condenser it's actually liquid..and actual valve component Ford

This applies to 2011 E250 cargo van, front air only? It has an accumulator
