I've got one of those do it yourself A/C chargers. What's the best way to get the freon in there? Can upside down or rightside up? I put a 14oz can in and I doesn't seem as if the second is going in. I know I need at least one more can after this to get it charged up.

Anyone done this before and have a few tips? Thanks

I've never done it with one of the do it yourself kits. Are you putting the charge in when the car is running and the a/c is on max full blast? If it is it should suck it right in without a problem.

You should always add the freon as a gas - there's a chance that "liquid" can damage compressor, valves, etc...

You can put the can down in some warm water to help empty the can faster...

this is correct. the freon should be added to the suction line (bigger line/low side) while the engine is running and a/c is on full. the can should be held straight up so the compressor can literally suck the freon from the can. DO NOT hold the can upside down. as BuffaloZone stated, this will cause ALL KINDS of problems including the possible lockup of the compressor.

Did your kit come with a guage? Get one if it didn't. Don't just guess on how much you think it needs, over-charging it is worse than not having enough. Put some in then check it and keep repeating that until you get it right. Also keep in mind that the compressor has to be running to get an accurate reading. Having a thermometer in one of the vents helps too.

Your fitting will only fit on the low side. You can turn the can upside down, you will not lockup your compressor.

Freon is cheap - New compressors aren't...

Good luck.

Yes, but he is using a little can, not a 30Lb jug with a 1/2 hose. By the time that the liquid gets to the compressor it will be evaporated. If you try to get every last ounce out of the can in vapor form it will be very hard. Like someone else said put it in a bucket of hot water, it raises the pressure. But if you are not sure and are not confident put it in right side up.

I've recharged the a/c in a several other vehicles, but not a stang. It works great for the summer...But by the spring it has leaked out again. It is usually only a temporary fix. If I was you, buy the can with dye in it as well, it will help you or a shop track down the leak.

"Liquid" installed into the "gas" section of the A/C system will still be "Liquid" - doesn't matter if it is 16 ounces or a "30Lb jug". That's why the "condenser" comes --after-- the compressor..and why the "evaporator" comes --before-- the compressor. And you don't just "Fill'r up" like you do a tank of unleaded - use scales.

I am by no means telling someone to charge a system as a liqiud. I am just saying that I do sometimes for certain reasons. The time the liquid gets to the compressor it will boil off to a vapor.(unless you just carelessly dump it in.) Remember IF the compressor is running it with be warm. Just because the refrigerant is in a certain spot in the system doesn't dictate what state it is in. Alot of different refrigerants must be charged in liquid state and large systems charge alot faster with liquid. Your right on the scale part, but that only works on one ocasion, when the system is totally empty and under vacuum. You can't charge by weight if you don't know how much gas leaked out. Sorry I got off the subject.

P.S. I am not flaming you just stating what I know.
