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

Works great highly recommend this product

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 took it to the company who said we must take off the dashboard and replace the evaporator. They injected it while filling up the gas. It's now two weeks and still perfectly cool, new gas used to last two days.

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.

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.

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

It didn’t work for me. And I passed the return period. Sad!

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!
