hey guys so i recently was changing my coolant hoses and loosened the bolt to the High Pressure A/C port. It blew out all the Refrigerant in a huge gust of steam. Now my a/c doesnt blow out anything but hot air. I went to walmart and bought the R134A Refrigerant bottle. followed the directions and notice after about 15 seconds of squeezing the trigger the refrigerant was just blowing out of the high pressure port between where the upper block meets the lower block.(not sure if thats what they are but we will call them blocks) Im just wondering if there is an oring or something, between the two blocks that came apart when i loosened the bolt, that got ruined. Should i just take it to a mechanic or is this something i can do on my own?

 

thats what i am thinking i will do.
