- 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

This was terrible. The hose is barely long enough to reach and still be able to push the button. The button itself is hard to push, the connection leaks so a good portion of it never makes it in. The can is still half full and nothing else will come out. Completely wasted money.

I rarely write reviews, but this is worth writing about. For starters, I am not an auto mechanic. However, based on my education and job I know more about A/C than the average consumer. Keep a few things in mind… almost all of the vehicle A/C refrigerant piping and coils are out of sight. So seeing a leak while looking under the hood is not likely going to happen. Also, you don’t know if you have 1 leak or 25 leaks (or zero leaks because the real problem is something else) or how large each leak is, so using this product (which costs less than filling your tank with gas) requires taking a leap of faith. I used it on a 2013 model year car that I would not be willing to put major $ into for fixing the A/C. I have an A/C refrigerant gauge set, and I had zero pressure on low and high side. I added a good part of a 12 oz can of R134a and once enough was in the system the compressor engaged. If the compressor won’t engage when adding a decent amount of R134a, then there is no point using this leak fixer product because that is not the main problem, and leaks may not be a problem at all. My car A/C system only held the R134a for about 1 day, before back to zero pressure. That rate of leakage is not encouraging, but does not mean all hope is lost. Think of the leaks you may have like a sheetrock wall with holes in it that you want to fix by spreading some “spackle”. If you have any hole in the wall that is large, like say 2” - 3” wide, you cannot reasonably expect some spread on paste/goo with the texture of peanut butter to magically “make the leap” across 2” and cure then hold to firmly seal the hole. However, you could have 99 or 999 much smaller holes in the wall that the spackle could easily cover. So if your A/C system has any 1 large hole, this product cannot work because that would require magic, but on 1 or a whole lot of tiny holes / leaks, this product has a decent chance of working. For me, it was worth paying for the can and giving it a try. I had tried some other brand that did nothing, probably because it only handled “rubbery” kind of material. This product also handles the other components that are not “rubbery”. I did this leak fix about 2-3 months ago and the A/C is still working great.

I thinknit worked. Didn't go into system as easy as I thought It would.

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
