+1 fix the problem, that crap does the same stuff you would with a radiator.... clog everything up!

you need to go to a real A/C guy, not that shade tree!

i like to see somewhere around 30-40 on the low side, and around 150 on the high side. if you're at 300 on the high side, you've got problems. usually caused by poor air flow across the condensor, or a plugged condensor. another possibility is a sticking expansion valve. sounds like you really need to have someone who knows what they are doing check your ride out, not some guy in a backyard using cans to fill you up.

well i appreciate everyboby's input.. ill see what i do next... definitelly no money right now to have a full ac service/repair....it looks like another hotass summer with no ac... thanks again.!
