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

I saw a lot of mixed reviews so I was going to add mine.I went to an air-conditioning repair shop local to me and that was their specialty . I spent several hundred dollars and they said it was fixed and I went out the door happy. This lasted 5 days.Two months later, I returned to the same shop and they said that my air conditioner pump had failed and again for several hundred dollars more they installed a new one.Both of these times within a week, the refrigerant was lost and luckily winter time came to Florida and I went back to 2 70 air conditioning (2windows 70 mph)I took it to another air-conditioning repair place and they quoted me $2400 to replace my air conditioner for everything that was needed. Here I am six months later with a hot truck.After doing some research, I decided to pull the trigger on this product. I followed the directions and inserted into the low pressure port and was able to get all of the material inside. Unfortunately there was not enough refrigerant inside to fill the system.Waiting a couple days I went to an auto parts store and bought refill kit and brought the system into the green. With the leaks I had before it would usually last 2 to 3 days before going back to blowing hot air again.It’s been three weeks now in Florida and I still have cold air blowing through the system like new. I’m not saying it will work for you but what I am saying is it worked for me and saved me $2000 to $3000 dollars plus time without my truck for work.

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.

Our 2016 Suburban with 200k miles had a small leak in the evaporator core behind the dash. It was losing about a can of Freon every 3 weeks. I did not wish to go through the labor intensive process of tearing out the whole dashboard to replace the evaporator core so I went looking at other solutions and found this Red Angel Stop Leak. While I usually am of the belief that stop leak products are mostly snake oil, I wanted to exhaust all of the options before doing major surgery. Getting the product in the system was tricky because the tight fit of the coupler and extremely short hose but was able to get it in with a few curse words. Topped off the system with R134 and took a long drive with AC full blast. I am pleased to say that it’s been almost 5 months and have not had to add any more refrigerant and the AC is still blowing ice cold. Your mileage may vary, but this definitely seems to have worked for us. Highly recommend.

I use it before in my pickup truck about 3 years ago and so far, doesn't have more leak issues.
