Red Angel 00222 A/C Stop Leak & Conditioner - 4.5 Ounce

Well, I put the Red Angel into my 2002 Oldsmobile Aurora 4.0 v8 that had leak that fully drained in 24 hours, I tried every stop leak on the market but it would always leak out by the next day,So I saw this advertised on an auto parts website but it was almost $50 so I tried looking for it on here at Amazon, I got the stuff on July 1, 2014 I read the directions on the can and it was basically start your car, turn the A/C on high and shoot the stuff in and fill it up with 134A coolant..it took all of 10 minutes..the only drawback was the can, the top was off the can when it arrived and I just put it back on and very little escaped from the top, now here it is July 4, 2014 and it is still blowing ice cold air, now it is too soon to tell, but I went over the 24 hour mark, here it is 96 hours later and it still works 100%.... I will keep you updated as the summer goes on, but I have a good feeling with the Red Angel UPDATE!!!!!!!! Sep 27th 2014 Well it is blowing warm air again. Here in PA it was kind of cold for the last 2 weeks so I did not use the AC but the other day it was hot, so I turned on the AC but no go, it was back to blowing warm air again, but honestly I am not disappointed at all because Last year I would fill it up with the R134A and by the next morning it was gone, so I used the red angel on July 1st and Sep 25th it was warm again(ok it was hot air lol) but I figure this....I spend $20/day to have AC(Nope) or I spend $30 for the Red Angel plus say $20 for 3 cans of R134A and it will get me through next summer? yes the Red Angel did not stop the leak, but it slowed it down so I could at least drive the summer with AC So to recap : The Red Angel sort of worked It got me through a summer using AC I spent $30 for the Red Angel and $24 for r134a (3 cans)(2 cans with the red angel 1 can to top it off on 8/17) so $54 to get me through the summer or a lot more than that NOT using Red Angel now it was Ice cold from 7/1/14 until 8/17/14 when it was blowing cold but not as cold as it was, I used 3/4th of 1 can of r134a and it was back to blowing Ice cold and lasted until 9/25/14...all in all I am pleased with the product.. I got over 2 1/2 months with the Red Angel VS 1 day with the other stop leak products on the market. Next Summer I am going to buy the Red Angel and 3 cans of R134a so I can hopefully get through another summer.... I hope this review helps someone decide whether or not to try this product because even though it stopped working it was cheaper to try this rather than fix my system for $800 on a 13 year old car with 160k miles on it... I will most definitely buy this product again

I purchased this stop leak & put it on my shelf as I was waiting for 134r Freon to arrive. I went to use it & the quick connect hose broke off as I was putting the quick connection on the air conditioning system, the red stop leak went everywhere & made a huge mess, now the hose won't stay on the can no matter what ! It's plastic & it's junk, it is now unusable & the return time expired & I lost out on the money I spent which sucks. Do not buy this product, oh yeah it took forever to arrive as well. I live in the desert & I really needed to have my air working. Don't buy this product, it turned into a huge pain in the a--. I didn't want to give it a single star but I had to, to post it. Signed, a very unhappy & hot customer !!!

After watching ChrisFix on Youtube, I was inspired to try and fix my AC on a 2007 Accord. First, I had to determine if a leak was the cause of my AC woes. I purchased an AC gauge and used it determine what my pressures where. I found that my pressures were extremely low compared to the Honda maintenance guide so I added some UV dye and r134a so the compressor would circulate the dye. I purchased an inexpensive UV flashlight from Home Depot and didn't see a leak. After a couple of days of using the AC, I went back under the hood and noticed a leak on the high pressure tubing coming off the compressor. It was leaking from the crimp that transitions the aluminum tubing to the flexible rubber hose as indicated in the photo on the right. The leak continued to grow so I decided to add the Red Angel and slowly added r134a to the prescribed pressure level while checking the blower temperature. Over pressurizing the system can damage the system, so I wanted to be very careful. I found Red Angel after researching various forums and found great reviews. I didn't want a product that would harm other components that would be really expensive to replace so this seemed like the most conservative product to use. After following the simple directions, I noticed after a day that the leak was still growing. I cleaned off the dye from the crimp and used the AC for another couple of days. After a few days, I noticed the leak was still present but it seemed to slow down. After a week the leak completely stopped. The picture on the left is the residual dye and it hasn't grown since. The AC has been working great and I now am confident that the system is sealed. Great product that saves money. Note: This isn't a miracle cure. It will only work for relatively minor leaks. If the hose is torn or the aluminum tubing is cut beyond a pinhole, the leak will not stop. You will either have to replace the part or patch the damage. Also, be patient with the product. As I described and confirmed with technical support, the product will not seal immediately. It takes awhile for it seal.

Works great

This is probably the best AC stop leak on the market, but the instructions are not sufficient. The first can I used didn't stop the leak, and the second also didn't, but the compound was still in the system, so realizing it is not having enough contact time with leaking area, I just filled the system again with refrigerant and let the car idle for 2-3 hours with the AC at max, and this time it did its job. It needed more time in contact with the leaking area, and having the AC on for several hours meant the compressor kept it circulating long enough to do it is job.

After 3 years of air con not working after being recharged twice, I thought that's it. Saw this product and decided to give it a go. After 4 weeks now and my ac is still working. Dunno how it's fixed it but so far so good. Bit expensive for such a little can but compared to having an ac specialist do the repair it's a bargain.

had a leak in the hose pipe which used to last for 2 months. used this product but it did not fix it. finally has the pipe replaced to fix the issue.

Shipping was super late, even Amazon felt it was late. Put the whole can in, drive for 15min. That’s it. Did not work. Wasted 90dollars. I will not recommend this product. Go get the 25 dollar Canadian tire leak pro. Those last longer
