My ac doesnt blow the coldest so i bought a recharge kit. when i took the black cap off the low pressure line it appears there is green antifreeze in the system somehow(i released some of the pressure with a screwdriver and it sprayed the antifreeze). i notice the smell of antifreeze sometimes when i get out of my jeep but have never seen a leak. anybody got any info on this?? i searched but came up with nothing, and im not sure what to do about this
