Red Angel Stop Leak - Need Advice
I'm already feeling pretty stupid for using this stuff, so please don't rag on me too much.
Anyway, I've been having a/c problems all Spring/Summer and have taken it to my regular mechanic shop several times. They've put the dye in with the recharge and haven't been able to locate the leak, and it keeps emptying out in about a week. They said they think it's probably behind the dash in the evaporator coil. The guy told me that if that's what it is, it' going to cost a ton of money and take a ton of time and they didn't seem too interested in doing the job. I contacted the Toyota dealership and they quoted me over $1600 to do the job, which didn't sound too great, either. The car is an '09 with 125k on it, so I figured it's probably not worth that, so I started looking online for other options. I found this Red Angel Stop Leak stuff that seems to have worked quite well for many people and they claim that it does not harm any recovery equipment and doesn't clog the system. Here's what they say: Quote:

It looks like you have a large refrigerant leak and your regular mechanic is not really geared up to do AC work and/or he's not really interested in doing it (as you said). A decent shop will have a refrigerant leak detector or "sniffer" that can detect a R134A leak even if it coming from the evaporator core in the dash. You can get a name brand one for around $100 on amazon or a cheap no name brand for as little as $20.
https://www.amazon.com/Robinair-TIFX...+leak+detector https://www.amazon.com/Elitech-WJL-6...+leak+detector If you want to tackle the leak yourself I'd suggest getting a cheap uv light from one of the auto parts stories or amazon/ebay and in dark garage or at night running it along all the AC lines under the hood. The AC lines are on the passenger side of the engine running from the firewall forward to the AC compressor under the alternator and the condenser behind the radiator. If there is a leak the neon green dye will be hard to miss with the uv light. Otherwise take to a shop that has a decent setup for working on AC systems. Also I wouldn't worry about the stop leak damaging their recovery machine as most or all of your refrigerant has leaked out and the remaining stop leak will be in the oil which is not sucked out when they put the system under a vacuum. |

also, if you're going to use a black light,get some CSI yellow tinted glasses as it will help in locating UV dye. i work for RobinAir. in the description of "oil based stopleak" it stays in the pag oil and has "velocity activation." at the end of deep recovery, the RRR machine will perform a "oil drain" cycle. it would pressurize the container that holds the oil/stopleak and opens a solenoid where it flows through a tube into a bottle. i could see it clogging the solenoid and tube. but they always get clogged. it's probably in my top 10 most frequent repairs...
