Air Conditioner Question

[Jason99DSM]

Well, my a/c is pretty much out of freon(sp?). I was at Auto Zone the other day and saw these little cans of a/c recharge. they looked like spray paint cans that supposedly you just hook up to the service port and recharge your a/c. Has anyone ever used these and know how they work?

first off you don't have freon if its a 99 you have r134.

where are you losing it from, mines a 97 and never been charged. you might want to take it to a shop. r134 is not expensive like freon.

 

[Jason99DSM]

so your thinking its probably a leak rather than it just being out? damn that would suck if it is :thumbdown

 

[diggerzmound]

They work, some have leak stop.

It isn't too expensive way to figure out you need to take it to the shop. Just might work if it is a very slow leak.

Before you take your car to the shop, ask how much it will be to look at it. Most small leaks can take some time to find. You can buy yourself a few of those R134 cans to last you a few years, compared to what a shop will charge you to look at it.

i bought two different cans of the r134a recharge stuff and both the nozzles didn't fit the nipple. thankfully the stores allowed me to return them. which one am i suppose to use??? help its hot out

 

[Attack Eagle]

then you did it wrong.

There are two A/C connectors, a High side and a low side.

you did the wrong one... unless your profile is wrong and you have a r12 vehicle like a 1g.

As long as you have a r-134 hose, it will fit a r-134 ac system. You probably tried connecting it to the hot side (High-pressure port) This is a larger port than the one for the R-134. You need to connect the recharge hose to the cold side (low-pressure port). They make the high-pressure port larger just for this reason, so you can't get them confused and hurt yourself.

The port you need is on one of the aluminum hoses coming out of the ac compressor. It will be near the compressor itself, facing the driver's side.

My guess is that you have a leak in your system. Which you should really take it to a shop and have them put dye in your system so the leak can be found. The leaks just going to get worse, and by adding R134 over and over again your doing nothing but wasting your money. Take it to a shop, and get it done right the first time. It should be under $100 to have them test and put some dye in the system.

^ I 2nd that.

Take it to a shop if you don't know what you are doing.

When trying to service the ac yourself, a good set of a/c manifold gauges (atleast) are needed to truly see what's going on with your system. Your system may be full but not cooling correctly. It's very dangerous blindly adding freon to your system. If you have to add freon, you have a leak. It could be something as simple as an o-ring or something more serious like the evaporator. A/C systems are 100% sealed and are not suppose to leak any freon, period. Also, when you have a leak, contaminates and moisture gets into the system. That will cause poor a/c performance, contaminate the system and possibly kill your compressor . Anytime you "open" the system to change an o-ring, compressor or whatever, you have to replace the ac drier and orifice tube at minimum. You also have to pull a vacuum on the system to get all the moisture out before you add more freon to the empty system.

This is why it's recommended to take your car to a professional.

I agreed with everything you said besides this, this is not needed. Just add alittle recommend oil to where you opened the system and call it good. I'm done my fair share of A/C work.

+2 on this part, Also the reason behind pulling the vaccum is to pull the freon back in the system when you recharge. With bigger systems the vacuum is sometimes not enough and the vehicle will have to be turned on and the remaining freon will get sucked into the system.

 

[tunethis]

Good info. I haven't done any a/c work on my Talon since I've yet to put it on the highway. Somewhere, I've read anytime the system is opened, those parts should be replaced. That may be a little extreme though. Unless, the system was completely empty. Atleast those parts are cheap if they have to be replaced.

ohhhhh that makes sense. i'll have to look for the other nozzle and then get yet another refill kit haha thanks

 

[donswan]

Yeah the low (which is the one an R-134 sysetem will fit on ) is on the drive side front near the tire. You will see a little green cap with an "L" on it that is the low. I just too mine out it's not that bad out and I live in texas just roll with the windows down.

 

[motozachl]

man i still can't find this. can someone snap a quick pic please? thanks

 

[Wildman95GS-T]

Mine is down beside the ac compressor, you will need a longer hose than any of the recharge kits have at the parts stores.
