BlueDevil Products Red Angel Automotive A/C Stop Leak & Conditioner | 2 oz.

Absolutely amazing I went to four different car dealers to get my air conditioning fixed All quoted me over $1,200, said my core needed to be replaced I took a gamble tried this product and it solved my problem this stuff I highly highly recommend if you're in the same situation It will save you a ton of money.

Simple process,delivered as stated.product works.

update new review : i was happy with the product because its held up pretty well for 2 month, after that month the a/c stopped working, and i had to replaced parts on my vehicle to fix the a/c problem and it damaged my pressure sensor due to the sealer. so overall the product only temporarily fixed my issue olds review: I'm very please with this product, I was having problems with my ac system last year and all the refrigerant leaked out within a couple of day after charging the system on my vehicle, i checked to see if any leaks were present and we not able to find a leak even with dye on the system. My thought were that the evaporator was leaking. I saw some good reviews and bad reviews about this product so i went ahead and gave it a try since the product had over 4 stars. i recovered my ac system and vacuum the system for 30 minutes, i installed the red angel a/c stop leak 2 ounce liquid in the a/c system before recharging the system, after i recharge the system with the refrigerant and ran the a/c for at least 15 minutes more like 30 minutes as instructed by the instructions. Its been about a month an a half and the a/c system is working like a champ. Ill be coming back to update my review and to let everyone know how good this product has worked for me

I evacuated my old car a/c system, put this product in quickly before air could get into the system through the leak. It has been 6 months of Florida summer and it is still leak free and working good. I didn’t think it was going to work, but it still surprises me how well it is holding up.

I initially had a slow refrigerant leak in my 1993 Audi. The system lost about 50g per month. A sniffer could not pinpoint the source, but I suspected the evaporator core. These cars lack low-pressure ports for adding refrigerant. I evacuated the system and added half a bottle of Red Angel. I was hesitant because stop-leak products can damage AC compressors. For several months, the AC functioned normally. Long-Term Results (1 Year Later) One year later, I had to disassemble the air handler. The evaporator still leaked. I now face major system problems. The mesh on my orifice tube is completely clogged. I also found unprecedented oxidation on internal AC components. I do not recommend this product. It is a waste of money and causes expensive repairs. I still have an unopened bottle I ordered because the hope dies last and I wanted to believe this was the magical solution. I will throw it away.

Finally got around to using this product at the end of August. 2015 Nissan Versa for reference. Had a very small leak causing Ac to blow hot within 1.5 months. True Evac and recharge on the small system. Followed the directions and No issues after 1 month. Will update review if product didnt work or caused premature failure of compressor/ac system.

Stopped the air leak. Sucks to need, but it worked.

Works great highly recommend this product

Made the leak worse 😞

Just used I auto A/C and seems to work perfectly

bought this product last june when in bullhead city az and it didnt work till the middle of july it[ was used every day]when on the way to canada then it leaked when i got to my destination purchased another in canada installed it[ end of july and its now the middle of sept] and it sealed with in 1/2 hr in bullhead there was no humidity and in canada the humidity was high enough for the a/c to drip on the pavement so i believe its definetly the humidity that makes it work even think it says on the bottle that fact [ installed #2 bottle at the end of july its now the middle of sept and is still sealed ]

I have a classic car (1984) that has a leaky AC compressor. I was refilling the r134a at the beginning of summer and within a few weeks it was all gone. I didn't want to shell out $3k for a new compressor/install, so thought I would give this a try but had little hopes of it working. I'm now going on 2 months+ of it holding the r134a, which is by far the longest I've ever seen. I don't know if it's permanently repaired, but even if I can make it through the entire summer would be a miracle. So it works!

Bloody good product!
