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 !!!

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.

It took a while after using this product to actually feel any improvement with the AC in my car. But after a couple months I felt a palpable difference and plan on buy a second cannister of this stop leak product, to complete the job. Its worth trying rather than facing the $$ burden of replacing an entire condenser or evaporator.

My 2012 vehicle developed a leak in the A/c evaporator, which would cost over $2500 to fix, since it requires removal of the dashboard. Previously, I tried a stop leak product available at the local discount store, but the Freon leaked out overnight. I decided to trade in the car because I can’t live another summer without a/c, but figured I’d give red angel a try before throwing in the towel. To my shock, the Freon did not leak out the next day and still blew amazingly cold air. I’m going on almost 2 weeks now and all is well. Also, many reviews criticized the dispenser and application, however, for me, it worked fine and I was able to see all of the the red product flow into my low pressure port. I highly recommend giving this product a shot when others fail before throwing in the towel on an expensive repair or trade in. Just carefully read and follow the instructions, cross your fingers, and see if it works like it did for me. I don’t know how long this will last but it was certainly worth the cost.

I used this on my '09 pickup. Here's a few things to think about. The directions on the can say to use this when the system is evacuated or significantly low on freon. That makes sense because if you used it on an A/C that's fully charged, you would overfill the system. It also says don't use it if the system leaks more than a pound of freon per day. That's a HUGE leak. My truck leaks a pound in about 6 months. So this should be ok. I saw some feedback that said the stuff in the can leaked all around the pushbutton on top, and some people struggled to get it to go into the system. So here's a tip: Most car A/C systems have a pressure switch that cuts out the compressor when the pressure in the low side suction line gets too low. The way you can tell your A/C is low on freon is to watch the compressor while the car is running, and if it keeps cutting out and back in, that's a sure sign the system is low. The thing to do is hook the hose from the can to the low side charge port, and then watch the compressor. Wait until it kicks off. Hit the button then. Hold it for 10 to 15 seconds or so, let it off, and then wait. The compressor will kick back on when the pressure rises far enough over the limit to trip the pressure switch. Again, wait until the compressor kicks off, that's the point at which the suction pressure is the lowest, and that's when it's the easiest to get the goo to go in. I did it this way until the can was empty. Yeah, a little leaked out from around the button on the top, but only a little. I got probably 98% of the stuff to go in. After that, I filled it the rest of the way up with a can of R134A. Also, (and it didn't say to do this, but I thought it might help), I left the truck running and took it for a 20 minute drive, just to make sure the stuff had circulated real well through the whole system. Now, whether fixed the leak or not is another story. This A/C needs to be charged about every 6 months, so I won't know if it worked until then. I'll update my review at that point.

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.

I had 2 small leaks within my automotive A/C system, both in areas with no moving parts, best suited for this product to chemically seal as designed. The leaks were identified with a Halogen Detector, considered to be too small easily diagnose with UV Dye. Based on the detectors leakage sensitivity level a leak of 6 oz/yr. was detected in the evaporator (looks like the evaporator was leaking in the center out of multiple areas) and 3.5 oz/yr. in the condenser (right in the center of it). Both pieces would need to be replaced so I figured this product would work. After applying a vacuum to the system, I first started with the A/C stop leak, applied the product as directed, dispensing the entire contents first. I followed this by charging the A/C system with refrigerant to capacity. Over the next 2 weeks I used the vehicle regularly with the air conditioner. After I re-verified if the leaks were still present, I found that the leakage rate in the evaporator was within the same leakage rate zone (4-6 oz/yr.) , while the condenser, may have been showing false positives, likely was still leaking, albeit a very marginal rate < (1 oz/yr.). I considered this unsuccessful. When attempting to call upon the product's well stated guarantee claim with the manufacturer (Blue Devil Products), I was ultimately met with this email: Grant- You may have seen on our website under the Warranty/Returns tab: "Any online purchases made from unauthorized re-sellers are not warranted by BlueDevil Products." Unfortunately, we are unable to honor the warranty for your purchase as we can not access your order through our Amazon Seller account. You may contact Amazon direct at 1-888-280-3321 to obtain your refund. Be sure to have your Amazon order number available when you call. Sincerely, Apparently, Amazon LLC is not an authorized re-seller since BDP has their own storefront on Amazon. Additionally, I inquired which retailers were considered authorized retail outlets; after which I was immediately met with supreme sarcasm that all major automotive retailers: AutoZone, OriellyAuto, NAPA (basically the typical brick and mortar store) are all authorized, as well as WalMart. They also kept redirecting me to see their Warranty and Returns page like as if I did not get the Memo. Yeah, since that is my primary goal, to go and decipher a company's red tape and determine every condition in which their warranty does or does not apply. To me, it sounds like a bs scapegoat to wiggle out of that guarantee so proudly slapped on every piece of marketing material they own. The correct answer would have been, "we are sorry our product did not work, could you try giving Amazon a call first and if they are not able to refund you directly, give us a call back and we will make it right! Does that sound good to you?" So if you plan to purchase this snake oil, make sure you do it at a brick and mortar store, or directly from BDP. I was gravely mistaken to think this product would work anyway. To put it into perspective, if DuPont, one of the largest chemical companies in the world, creators and pioneers of most refrigeration chemical technology has not come up with a viable leak sealer with their massive R&D budget, then most likely, neither has anyone else. Note: Amazon was nice enough to cover the warranty (refund or replacement at your discretion) for this product, and will do so for 365 days from the date of purchase. The Amazon representative stated warranty claims are charged back to BDP.
