Hey guys,

I just did a motor swap on my car, taking out the engine and all the other stuff. So now i came back to put the A/c on and i put in one can 12oz of 134a and the aux fan kicked in and is working but the air isnt cold enough to put in the system. the system was bone dry as i had to take out the AC lines and do a full swap from one motor to another. Thanks for you help in advance

How many cans of 134a should i put in? and at what pressure should it be at?
