You don't pour it in, you insert it through one on the jacks using the proper hose.

 

but see the a/c flush i looked at, was in a rubber bottle with a twist off cap (like motor oil) so how would i hook that to a hose to insert it is what im sayin...

 

ok i think what u do is put it through your condensor and let it run through all of the lines...then u have to get the vaccumm kit and use that through all of the lines...then turn the ac on as hard and cold as it gets then put your freeon and oil back in...the retrofit kits (the blue boxes) go on lowside ports...the blue hose with the blue and black adaptor...the gold adaptor is high side...the kit comes with everything needed to convert besides flush and vaccumm kit....like i said...get ben to get it for u for cheap
