BlueDevil Products Red Angel A/C Stop Leak and Conditioner

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.

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.

Its a bit fiddly to use but it seems to have worked.

Still not used!

المنتج لا يوقف التسريب ولكن يؤخر عملية تعبئة الغاز، عن نفسي قبل استخدام المنتج كنت أقوم بتعبئة الغاز كل ستة أشهر وبعد استخدام المنتج قمت بتعبئة الغاز بعد سنة، تم شراء المنتج للمرة الثانية

great solution that save load of money

Delay the refill and extend the time in case an AC leakage exists

It saved me 2000$, recommended

Works great

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

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.

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

Worth nothing more than a bottle of water in pressure container. So do not waist your money on such product.
