Default Stop Leak in auto air conditioning

I just got the news that my 2004 chevey truck needs a new evaprator. It is going to cost $1000.00. It looses its charge in a week. I know that there is Stop Leak for air conditioning and it's contriversal but I would like to try it .
What kind of experience have you all had with it?

Thanks
JD

Don't use it. All your going to do is get that crap in all the good parts such as the compressor and condenser.

Don't do it. Replace the evaporator yourself for $117.

Very bad idea, compressors on those are marginal to start with, dumping that crap in the system will cost you a compressor and condenser at the very least, in addition to not permanently sealing the leak because it's too large. No A/C shop that knows what is doing will hook a veh with that junk in it to their recovery equipment.

It isn't the parts, it's removing and disassembling the dash and evaporator case. It pays about 10 hours. Not the easiest job in the world, take lots of pictures, figure on having it apart for a couple of days.

I understand that. I'm just offering encouragement to the poster that he do it himself for $117 out-of-pocket.

And I'm just explaining why they want so much to do the repair...

Like I said it's doable but fairly intimidating.

I just did one on my Jeep. PITA, yes, but well worth the savings. Helps if you have a manual and be sure to take some pics/notes during disassembly. Also, be sure to replace your accumulator as well. Autozone has a vacuum pump and gauges on their loan a tool program so that'll be free. They also have a good DVD on auto a/c, worth a watch if this is your first time.

Don't put that crap in there or you will probably be facing a firewall forward replacement of everything in the future if you ever want cold air.

Default Re: Stop Leak in auto air conditioning

i try to fix stuff "properly" but realistically sometimes to fix the a/c is worth more than the car. this stuff works well for those situations and does not f up a shops a/c equipment. As i really dont have another 5k to spend on a new machine at work. pretty much if you can pull a vacuum on it for a period of time, this stuff will seal it up.

http://www.usasealants.com/products/...k-conditioner/

and the faq's about it:

Will it clog the recovery unit or any other A/C components?
No. Red Angel is completely safe for shop equipment and A/C units.

How does it work?
Red Angel is inert until it mixes with R-12 or R-134a. Red Angel is activated by air flow at the site of the leak - forming a chemical weld and repairing the system.

How large of a leak does it repair?
Red Angel will seal leaks in A/C systems that can hold 5 inches of vacuum for 25 minutes or 15 inches of vacuum for 5 minutes.

Does it seal evaporator leaks?
Yes. It also seals leaks in connection hoses, gaskets, o-rings & condensers.

How much do I use?
Use one bottle (2 oz.) for all automotive A/C systems (up to 5 lb. system). When adding Red Angel to an evacuated system, substitute 2 oz. Red Angel for 2 oz. of oil. When a vehicle has a slow leak & maintains a partial charge, add 2 oz. of Red Angel along with the necessary amount of R-12 or R-134a (see service manual).

How long will it stay in the system?
If there are no leaks in the system, Red Angel remains as a liquid lubricant in the system. It can stay in the system until the oil is reclaimed.

What happens if I recycle the refrigerant?
Red Angel is removed from the A/C system with the refrigerant. It is then separated from the refrigerant with the reclaimed oil.

Can I install it without an oil injector?
No, you must use an oil injector.

Not to sound rude but I could give a rats ass what the manufacturer says about their stop leak. If it will clog up a hole with 100 psi behind it, then it will clog up my machine. Not worth the risk and I wont touch anything that has had stop leak in it.

We lost our last r12 machine to stop leak. Not worth replacing it with another....sucks too because we were one of the last shops in the area that still serviced r12 systems with r12 instead of a retrofit

my r12 and 134 machine is still going. it has been in contact w/ this stuff. like i said,it is not a go to but a last resort. take it for what it is worth.

also, what r12 machine do you have? i have a spare snap on r12 machine that i have stashed for parts for mine.

I pissed off two mechanics I work with last week when I told them that they didn't have a clue what they were doing after I seen them put stop leak in the bosses truck. Needless to day that went over well, first they asked what i would have done and then they told me if I didn't like it that I could fix it myself.

some shops will pass on servicing your a/c system if they know it has that crap in it.

When I was working in the dealership and customers would complain how much it was I would tell them A/C is a luxury. If you want it you gotta pay for it.
I wouldnt put stop leak in the A/C system. Just fix it the right way and be done with it.
