Do you have an expensive leak in your automobile? Well, we know that sometimes fixing the hard part on your car just isn’t an option. If it’s not in your budget or the car is simply not worth it, perhaps a chemical stop leak product is the answer!
A new generation of stop leaks emerging in the marketplace is working hard to shed the old reputation of stop leaks as dangerous “snake oils” that do more harm than good. This includes an oil-based stop leak for mobile air conditioners (A/C) that reacts at the leak point only while lubricating and conditioning the system.
Accompanying the new style of A/C stop leak is a chemical sealant for cooling system leaks that does not use any harmful metallic filings or pellets to plug the leak. These new stop leaks are comparable to hard part repairs in a variety of ways at a fraction of the cost. The products provide reliable repairs for customers who cannot afford an expensive repair cost or for a vehicle in which the owner decides is no longer worth spending a lot of time and money.
The bad reputation of air conditioning stop leaks
Air conditioning stop leaks have been a long-time enemy of service technicians and their recovery equipment, compressors and orifice tubes. With limited success at actually stopping leaks, early A/C sealers do far more harm than good by crystallizing throughout the system. These stop leaks react to moisture and oxygen at the leak point. The leak is moderately sealed, lasting at best for a few months. The danger of these sealants is that the remaining product continues to react with the moisture in the system. The most common place for moisture in the A/C system is the orifice tubes where condensation is ever present. This causes crystallization of the stop leak in these hoses, which eventually clogs the system. Furthermore, these crystals move into the compressor, causing it to fail within three to six months. Once the vehicle is brought in for service, an unsuspecting technician recovers the system immediately sucking these crystals in, contaminating the machine and rendering a $2,500- $5,000 piece of equipment useless. After reviewing this chronology of events, it is readily apparent how previous stop leaks got such a bad reputation.
How do new air conditioning stop leaks work?
The new oil-based stop leaks have a tough road ahead overcoming the negative connotations brought about by existing A/C stop leaks. However, this new era of sealant works in an entirely different fashion. Oil-based stop leaks are activated by pressure and flow velocity at the leak point. The oil acts as a lubricant and is compatible with the PAG or ester oil already present in the A/C system. The stop leak is inert when injected into the system through the low side port. The refrigerant charge activates the molecules in the sealant as it reacts to flow velocity at the leak point only. The result is a flexible yet strong repair.
Once the leak is sealed, the remaining oil will continue to lubricate the system. Therefore, there is never any crystallization in the orifice tubes, no damaged compressors and, most importantly, if the system is ever recovered, the remaining stop leak is reclaimed with the oil, keeping the recovery machine safe and technicians happy.
Endless marketing opportunities for A/C stop leaks
Because this type of stop leak is safe for equipment, easy to use and compatible with a variety of refrigerants, its marketability is infinite. Service technicians can use it as preventive maintenance with almost any repair job. The oil will remain as an inert lubricant in the system waiting for a leak to present itself.
The amount of time and money saved repairing minor leaks results in larger profits and easier sales with a working air conditioner. Depending on the vehicle model, replacing a compressor or evaporator can cost anywhere from $600 to $2,000. There are a lot of vehicles on the road that are not worth that much and a lot of people who can’t afford the expensive repair. Repair facilities can develop lasting relationships with customers by helping them save money when the hard part repair is not an option, while still making a profit on the system recovery and new charge. Positive word of mouth will spread, creating new business for the shops offering the oil-based stop leak as a treatment option.
Red Angel A/C Stop Leaks and “One Shot” takes less than 15 minutes to circulate through the system, sealing any leaks. Its compatibility with a variety of refrigerants also separates itself from its predecessors. This new type of stop leak is compatible with R-134a, R-12 and R-22, as well as newer environmentally safe refrigerants. This compatibility will open the market beyond the automotive industry into home A/C applications as well. The potential for this new air conditioning stop leak is boundless because of its safety, ease of use and compatibility with a variety of vehicles and equipment.

With the compressor not kicking on do I need to add some refrigerate first then the stop leak or does it matter.
Andrew-
You will add the Red Angel A/C Stop Leak first and then the proper recharge of refrigerant.
Thank you!
-BDP
I don’t understand the response you gave to Andrew. If the compressor is not running, how will the Stop Leak seal the leak before adding refrigerant? My logic wants to say add a small amount of refrigerant first to get the compressor to come on, THEN add the Stop Leak and let it circulate, and then finally recharge the system to spec. Am I wrong?
Sara,
Thanks for your question. Your logic is correct in that you need enough pressure in your system to get the compressor to engage. Most often, small leaks don’t leave your system completely empty and the pressure added by the Red Angel AC Stop Leak Aerosol is enough to allow the system to restart. If that isn’t the case then you would need to add refrigerant until the pressure is high enough for the compressor to cycle.
Thanks again for your question!
-BD Auto Pro
BDP,
You are not wrong, but you missed a step. It is a good idea to perform a min. charge to the system enough to circulate the Red Angel at least 10 – 15 mins (unless you recommend longer), after you have introduced the stop leak. Then you need to pull a vacuum on the system to remove the moisture and static air (Autozone, has a free loaner program). If you don’t have a digital gauge with microns of vacuum, then run the vacuum 1-2 hours using analog gauges (dial). Then isolate the pump without disconnecting it and let it sit (provided all your hoses and gauges are in good working order), your system should hold that vacuum indefinitely (I would let it sit for 1-2 hours). If the dial does not move, then you may introduce the measured charge of refrigerant. If you have met all the conditions, your system should be ice cold and should last a while with the aide of Red Devil. If you have a digital gauge (proof that your Red Devil has done its job), you should be able to pull a vacuum down to 500 microns (the time for that to take place depends on how much moisture is in the system; could be an hour or 3 hours, etc.). I did a system down to 750 microns (only because the customer couldn’t wait) and the system worked great. The first time I charged that system the vacuum couldn’t get past 1000 micorns due to a leak (so, if your system can’t past 1000 micons or is all over the place with the reading, you probably still have a leak and need to repeat the precharge and circulate procedure). THE RED DEVIL DID ITS JOB FOR ME!! Thank you RED DEVIL Dan
Dan-
We are happy to hear of the success you’ve had with the Red Angel A/C Stop Leak! Thank you for your positive feedback and detailed insight. Once the product seals, it would be a permanent seal, so you should be good to go at this point.

Your Ford Edge would require R-134a refrigerant. Feel free to contact our technical support line at 888-863-0426 with any other questions.
Thank you!
-BDP
Can this product be used in a isobutane like r6001
John-
The Red Angel A/C Stop Leak is only intended for R-134a. Unfortunately, we do not manufacture a product intended for R6001.
Thank you!
-BDP
Yes, you need some pressure in the system to activate the compressor clutch which pumps the product into the system or you can jump the connector out to engage the clutch. Either way you will still have to fill the system with R134 for the stop leak to work.
Put enough in to activate the compressor then top the system off so you don’t over fill.
It actually is a good idea to jump the clutch connection first to make sure it is not the problem.
so if leak from compressor this product will not help??
Wan-
Yes, the Red Angel A/C Stop Leak is not intended for compressor leaks. A hard part repair would be your best option.

Aren’t there o rings in the compressor that can leak and be inflated by the swelled by the sealer? Is any leak from the compressor mean it must be replaced?
Roy-
The Red Angel A/C Stop Leak is not intended for compressor leaks. However, leaking o-rings, connection hoses or even gaskets would be good candidates for the product. Feel free to contact our technical support line at 888-863-0426 with any other questions.

If it’s a hose or seal leak can’t you just replace the hose or seal? The expensive part is the compressor but it sounds like this product does not fix a compressor leak.
Bobby-
Yes, you would be able to replace a leaking hose or seal. The Red Angel A/C Refrigerant Stop Leak is not intended for compressor leaks. Replacing the compressor would be your best option.
Thank you!
-BDP
you need a compressor if it wont come on if it doesnt spin when you turn on your ac replace it with a used one from a junkyard for very low cost
Wrong Patty Mady. It could have simply have leaked all the R-134a out of the system. Hence needing the stop leak to begin with. If the system is to low on Freon, turning the AC control on will do nothing to make the compressor cycle(if it did, your compressor would destroy itself). There are high and low pressure switches that tell the compressor when it is safe to turn on. To low of pressure and no signal to tell the compressor to turn on. I wouldn’t recommend telling someone to run out and purchase a compressor. That was bad information right there.
Yeah these new cars and trucks have a safety system on them and if your refrigerant gets low pressure it will not allow your compressor to cut on. My vehicle is doing that right now I can charge it and it will work for about 2 to 3 weeks untill it leaks it out again. I’m going to give this stuff a try. What year model is your vehicle?
How we add this stop leak in refrigerant and how does this stop leak work explain briefly please?
Karan-
The Red Angel A/C Stop Leak has a quick connect hose that will attach directly to the low side service port. After removing the tab from the can you may connect the coupler to the low side service port, with the engine on and A/C set to max, and depress the button on the top of the can to inject the Red Angel. After the full contents of the can are released you may recharge the A/C system with the proper amount of R-134a.

Hello BDP,
I came across an advertisement for your A/C Stop Leak product…
I have a 2001 Chrysler PT Cruiser I recently had the compressor, receiver drier, hoses and o-rings.
My mechanic stated the the only thing left was the evaporator core unit and that required the complete removal of the dash down to the firewall to obtain access… and his quote for the labor alone was $1500.
I declined to have the work done… Being a commercial aircraft mechanic I decided to try and tackle the job of replacing the evaporator myself. I took as much of the dash apart as I could and ran into a road block where I could not find any other parts to remove to gain further access to the evaporator… I think the dang thing was welded in place. Long story short – I put the car back together and am stuck with a non operative A/C which sucks big time as I live in south Florida… I am considering giving BDP A/C stop leak a try… I’m trying to determine whether to use the aerosol or the liquid, I’m leaning towards the aerosol as I don’t have the equipment to use the liquid.
Charles
Charles,
Thanks for your question about your PT Cruiser. Replacing the evaporator in almost any care is a significant project, but especially so in yours so do not be discouraged with your project. We would also recommend using the BlueDevil Red Angel AC Stop Leak aerosol as it is easy to use and doesn’t require special tools. The liquid and injector are designed more for garages who will be repairing multiple vehicles. If you have a leak in your evaporator BlueDevil Red Angel AC Stop Leak will seal the leak, then you can recharge your system and get back to having cool air.
Thanks again for your question!
-BD Auto pro
I have a pretty large leak that developed in the condenser unit. it leaks out as i’m trying to fill the system. Will the
Red Angel AC sealant work on this type of condenser leak?
Mark-
Based on your description, you may be losing refrigerant a little too quickly for the product. A system that won’t hold 5 inches of vacuum on the low side for 25 minutes has a leak that is too large to be sealed, and may require a hard part repair.
Thank you!
-BDP
I replaced the air compressor, orifice tube and A/C Accumulator/Receiver Drier on my 2004 Ford E-250. I have a slow leak, takes months for it to lose all Freon. I currently charged the system. Can I add stop leak to it now? Or do I need to evacuate, vacuum and recharge it again? Thanks.
Rob-
Yes, it would be safe to add the Red Angel A/C Stop Leak Aerosol(http://store.gobdp.com/a-c-stop-leak-aerosol-00222/) now; the system can either be empty or partially depleted when adding Red Angel.
Thank you!

My 02 GMC Sierra was diagnosed with a coil leak 2 years ago when the AC first stopped working. No way to tell if the dye showed up there without ripping dash apart $700.00 bucks so I just dealt without AC. My question is after two years should I evacuate the system before trying this product and also will I need to partially charge system to get compressor to start before adding stop leak and then top off with more refrigerant after adding the stop leak?
Gregg-
You should add Red Angel A/C Stop Leak first and then recharge the system with the proper amount of refrigerant. Next you should allow the A/C to run on the maximum setting for 15 – 20 minuted to allow Red Angel to circulate.
Thank you!

I have a Toyota Corolla 1996. Last year I filled the A/C with Freon and it lasted until the end of summer. This year I did the same but it only lasted a few days. I went to a garage and the mechanic checked the system for leaks. He found no leaks under the hood and told me that the leak must be inside the car. He has to take the dashboard off and fix whatever doesn’t work (probably the evaporator or condenser?). He told me that the job may cost up to $800-900. I came across your product, BlueDevil Red Angel AC Stop Leak aerosol and I wonder if this may fix the problem. Should I go back and ask him to try this Red Angel product? What do you think?
Thank you

hello , will this work in hybrid vehicles that uses nd-11 oil?
Ismael-
Unfortunately, we do not recommend using Red Angel in vehicles that have an electrically driven compressor. Hybrid vehicles use electrically driven compressors which require very specific conductive oil.
Thank you!
-BDP
Why doesn’t the can say “not for hybrid electric driven systems” like every other stop leak product on the market? Your website states it is compatible with all PAG and Ester oils, it’s my understanding nd 11 is an Ester oil. I just used your product in my 2006 prius based on what I’d read on your website and your lack of the “standard hybrid” on the can. I hope my car is ok and your over sight in labeling is not market driven !!
Rusty-
Our current labeling does state “not for use in electrically driven compressor systems”. It sounds like you may have purchased a can that was manufactured years back and had old labeling. Literally the only oil that is compatible with electrically driven compressors is ND-11. The owner’s manual for the Prius specifically states “CAUTION: Use only ND11 type compressor oil”. ND-11 oil provides high dielectric properties, which help maintain the integrity of the compressor’s electrical windings.
To be on the safe side, we recommend that the A/C system is evacuated and recharged.
Thank you!
-BDP
My AC evaporator is leaking in my 2000 Cherokee classic and it takes several days before I realize that it is no longer cooling. Would that be considered partially evacuated at that point so I can try your product?
Jeremy-
Yes, it would be safe to add Red Angel A/C Stop Leak at this point. The system is definitely partially depleted if it is no longer cooling properly. After injecting Red Angel you will want to add the proper amount of R-134a to recharge the A/C system.
Thank you!

I have a ’78 Lincoln Mark V 460. 21K miles. It is a show car, so don’t really want to convert it unless absolutely necessary. AC compressor seized and was replaced about 10 years ago. About 5-6 years ago, was leaking R12, my mechanic used dye, foudn a leak, replaced the evaporator O-ring. Charged it up, within a week was blowing warm again (haven’ tbeen back to him since). Currently even with car idling the hose from radiator side to firewall gets icy, but air inside the car is not cold. So I think that means it coudl be low on R12. I suspect htere is still a leak somewhere. About to take it in next week to a different mechanic for leak testing. If he can’t fix it I may give this Red Angel A/C Stop Leak a try. It sounds like it should be compatible with my old R-12 system. Does it come with the necessary valves to attach to my R-12 low-pressure fitting?
Tim-
Thank you for asking about your Lincoln. You would need an oil injector in order to properly add the Red Angel A/C Stop Leak. Based on your description, it does not sound like you are losing refrigerant too quickly, so you would be a great candidate for the product.

So I put a can of R134a in. Now its early September and I’ve noticed a significant decrease in cooling. It still cools, but we’re only in the high 80’s and it doesn’t really get cold on high like it should. My questions are: 1. Should I just let it leak out and start fresh in May or recharge now? 2.

Hi ,
I have a 2010 Mercedes B200 with only 29000Kms on the clock , I had my mechanic re gas it the first week of January , only to feel the hot air coming through here in Sydneys Summer the last week of February , so lasted approx 6 weeks. They checked it the other day, and found a leak on a coupling between the rubber tube and metal tube underneath .
To replace the tube throughout is $400 odd just for the pipe and tubing , then ;labout so up to $900 time its all done .
I said to him is there not anything that can seal that small coupling leak and he said no , not that he had heard of .
Do you think your product would work here as sounds like it would reading the other comments here

Hello there, I have a 2005 Prius with an extremely small leak in the evaporator (takes about a month for the ac to stop blowing cold.) I understand that it’s not recommended to use red devil in hybrid vehicles because of the lack of compatibility with oils for electrically driven compressors. My question is: will using red devil in a hybrid DEFINTELY kill the compressor? Without a doubt?
Thanks
Angelo-
Unfortunately, we do not recommend using the product in your Prius as you should not use Red Angel in electrically driven compressors. Using anything but the recommended oil would compromise the system.

Hi, my 1998 Ford Ranger 2.5L stopped blowing cold several years ago. I never repaired the leak, but recently decided I’d like A/C again. A professional A/C shop diagnosed a leaking compressor seal, but of course rather than just replacing the compressor they recommend changing many things because of wear and the possibility of junk clogging the lines, which is also they only way to obtain a warranty.
I decided to try a recharge from a discount recharger first. He added an inexpensive stop leak with dye that I bought at Walmart, then recharged the system. He didn’t see any leaks, but the A/C only remained cold for about two weeks, and is now blowing slightly cool. Since the system was dry for so long I wonder if the hoses and seals absorbed freon, and now that they’re “conditioned” if another recharge would resolve the issue. Does it sound like your product would be helpful?
Paul-
Thank you for asking about your Ford Ranger. Based on the initial diagnosis from the A/C shop, the Red Angel A/C Stop Leak would not be of any help, as it is not intended for leaking compressors. We recommend having the compressor replaced and getting your A/C back to normal working condition.
Thank you!

I added the red angel as per instructions. When I went add r134 it would not flow into the system.
Any ideas?
Doug-
It sounds as though the system might have been full. Did you evacuate the system prior to adding the Red Angel A/C Stop Leak? Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s condition and be able to make any appropriate recommendations.
Thank you!

I have a 1998 Chevy truck that recently had the entire A/C system replaced with a BRAND NEW (not Factory Remanufactured) compressor and evaporator. After the service center recharged with freon the system worked purr-fectly on my lengthy drive throughout our vast metropolitan area that day.
However, in that I work out of a home office and do not have to use my truck EVERY day, two days later as I left to run errands I found that… I was back to where I started initially – before having the part replaced (including new ‘o’ rings, etc.).
I called around and found a highly recommended “auto A/C specialist” who tested the system NOT WITH a dye, recharged freon then a dance under the “black light”s but, instead, used Nitrogen gas to ‘recharge’ the system then swab connections, hoses and metal fittings with a solution that would show him where the leak was originating. As well, I was told, the gas would push what remains inside the compressor and/or evaporator outside the hardware IF there were any imperfections in these brand new parts.
He was unable to detect any leaks. He then suggested I might consider putting your product in, then recharging w/freon to fix the phantom leak.
A friend of mine, many decades working at a GM dealership and (as an auto collector himself) has worked with many technicians over those decades. When this loss of cooling in my A/C system started I recall him saying “God forbid the leak is in the portion of the closed system on the passenger side of the firewall. THEN it would REALLY be an expensive repair – diagnosing, tearing apart the dash to get at and replace what was needed there…”
SO my question to you would be: All this taken into account (BRAND NEW parts with no sign of leaking) and nothing found with the Nitrogen gas test might it just be “the solution” I have been looking for having the “A/C specialist” I went to for testing put your product in and help me better survive this godforsaken “monsoon” season here in losangePhoenix?
Mike-
Thank you for asking about your Chevy Truck. Based on your detailed description, we would recommend using the Red Angel A/C Stop Leak (http://store.gobdp.com/a-c-stop-leak-aerosol-00222/). The product can actually also be used as a preventative measure as well. So even though it is uncertain where the leak is coming from, it would not harm the system in anyway to add the product in hopes of sealing the “phantom” leak.
Thank you!

Hi, we have an 05 Chevy Trailblazer that has been having some cooling issues. The previous owner stated that they’d need to add refrigerant every summer to keep the ac cooling sufficiently. We live in South Louisiana and it’s scorching hot here right now. Just recently we went to add refridgerant and it was blowing cold for about 2 weeks. Once it wasn’t blowing cold anymore my husband evacuated the system and then added the refrigerant. Again in a couple of weeks we were back to square 1 with the ac not cooling. Took it to a shop who suggested replacing the orifice tube and condenser. So we bought the parts and they installed them then charged the system. Once again, we had cool air for about 2 weeks. When hubby went to look everything over he realized the Schrader valve on the low pressure side was leaking so he replaced the valve and both the low and high pressure switch. Once again he evacuated and recharged the system. This time the ac would only blow cold for 10-14 days. He also tried adding dye to check for leaks and wasn’t able to find anything. Would we be a good candidate for your product?
Amy-
Thank you for asking about your Chevy Trailblazer. Based on your description, we recommend using the Red Angel A/C Stop Leak (http://store.gobdp.com/a-c-stop-leak-aerosol-00222/). Although it is difficult to say where the leak is occurring, it does not sound like you are losing refrigerant too quickly, making the vehicle a great candidate for the product.
Thank you!

I had a very obvious hole in the rubber part of the suction hose that was caused by friction rubbing. I spliced the hose with AC hose end splicers and clamps. My system is completely empty and it takes 40 OZs
I purchased 36 OZs of R134 and want to use a can of REd devil as well. I figure this may act as a back up to the splice repair. So w/ 40 OZs of need roughly how much R134 shld I put in before I cycle in the red devil? How many OZs is th red devil.
Robert-
In terms of adding the Red Angel A/C Stop Leak (http://store.gobdp.com/a-c-stop-leak-aerosol-00222/), you should be adding it to a system that is evacuated or partially depleted. The product itself contains 2.5 oz. of R-134a. Once you have dispensed the product, you would be able to top it off with R-134a.
Thank you!

Is this stop leak hybrid vehicle safe? Electric compressors so oil needs to be non conductive.
Marco-
Unfortunately, we do not recommend using Red Angel in vehicles that have an electrically driven compressor. Hybrid vehicles use electrically driven compressors which require very specific conductive oil. A hard part repair may be your best option.
Thank you!

Hi I’m curious as a mechanic in training and aspiring to become an owner of a shop, would this sealant damage or shorten the life of recovery equipment? In shops I’ve worked for here in Colorado, we turn down every vehicle that tests positive for sealant and for good reason; being that we do not want to damage a $5000 plus piece of equipment
Chris-
No, the Red Angel A/C Stop Leak would not damage or shorten the life of recovery equipment. The product does not contain any solid or particulate matter that will clog the A/C system, or harm a recovery unit.
Activated at the leak point only, Red Angel will not crystalize with existing oxygen or moisture in the system. After repair is achieved, the product will continue to lubricate and condition working components. You can use Red Angel as a repair, preventative maintenance, or to warranty hard part replacement against future leak points.
Thank you!

I’ve always heard to avoid introducing air into the a/c system. When using the red angel stop leak product that is pressurized with r134a, will the amount of air present in the hose create any issues?
Is there any way to further minimize the introduction of air into the system?
I can pull a vacuum on the system and have a gauge set.
Buddy,
Thanks for your question about your air conditioning system. It is best to not introduce air into your air conditioning system as it carries moisture with it and takes the place of a small amount of refrigerant. If you are using the Red Angel A/C Stop Leak and Conditioner aerosol can the amount of air in the hose will not affect your system. If you are adding Red Angel A/C Stop Leak using your own equipment, you should be able to add it the same way you would add a charge of refrigerant.
Thanks again for your question!

Hi, i own a Suzuki kizashi CVT 2013 model. My car ac stopped working a couple of days back now all i hear is a whizzing sound when i start the AC and a weird smell. My mechanic diagnosed it as an evaporator coil leak. He needs to open the whole dashboard and asked me to leave the car for a couple of days…this would cost me upwards of a grand. Could your product help. Is it available in India or do u ship overseas..do let me know

Hi,
Every time when I recharge a Freon to my Armada model 2009, the Freon will no longer be exists after 2 weeks ! the condenser working fine but all technicians have recommended to replace the evaporator, but I don’t want to go deeply in replacing such evaporator which will cost a lot of money and removing the whole dashboard. Does Red Angel A/C stop leak will assist in preventing such leak from the evaporator.
Do you have any retail shop in Dubai.
Thanks,
Mahmoud
Mahmoud-
Thank you for asking about your Nissan Armada. Yes, the Red Angel A/C Stop Leak would be able to seal an evaporator leak. We not have any retail shops in Dubai, however, you may purchase the product directly on our website. Here is the link, https://store.gobdp.com/a-c-stop-leak-aerosol-00222/

May 2017; My trusted shop (of 25 years) said my 2000 Dodge Grand Caravan (261K orig miles) very likely had a leak in the evaporator coil. No dye seen anywhere else. Compressor had been replaced years earlier. Cost to fix evap coil > van’s worth. Began long read on Red Angel. Although my shop was a bit skeptical, I convinced them to let me be their guinea pig with your Red Angel product. I wanted them to do it for their 1st hand testimonial ability even if I could have done it. My shop had said this was a one shot deal with the Red Angel and if the leak returned they said Red Angel could not be added to my system again. I didn’t challenge them on that. Now it is June 2018: System is not blowing very cold and seems sporadic. I was very happy to get a year of cooling since very economical. I read above where you say it is OK to give Red Devil more tries – true, right? Why would a veteran shop say “one time” use? Maybe they were thinking its like other ac-leak sealers?
Ronald-
You are correct. Red Angel A/C Stop Leak could safely be used more than once if the leak still persists. It is possible that previous experiences with other A/C sealers have given the shop this impression. Red Angel will not clog or damage the recovery unit and is removed with the reclaimed oil. Red Angel A/C Stop Leak can be utilized as a repair, preventative maintenance and to warranty hard part replacement against future leak points.
Thank you!

my 2004 grand cherokee ac has a capacity of 27 ounces of r134a. if i add your red angle , 4.5 oz can how much r134a should i add after the red angle? do not wish to overcharge. thanks.
Ken-
Thank you for asking about your Grand Cherokee. The Red Angel A/C Stop Leak contains 2.5 ounces of R-134a. Adding the product to a system that has been fully evacuated, you would top it off with 24.5 ounces of R-134a, after applying the product.
Thank you!
-BDP
I just put a can of your product in. But I know I have a pretty bad leak, enough to go through 4-5 cans in a month or two. Can you recommend another product for compressor leaks? I put dye in as well and it looks like the only indicators are splatter on the very port where I charged the system. Thanks. It’s a 2004 Lincoln LS.
Heather-
Thank you for asking about your Lincoln LS. Unfortunately, there is not a product on the market intended to treat leaking compressors. Replacing the compressor may be your best option.
Thank you!

I added the stop leak my car engine stalled and my compressor stopped. Why. Is there a fuse blown. No ac only outside air. I would assume the clutch did not engage.
Byron-
Did the compressor kick on initially? When dust, grime and/or mineral scales build up on the condenser coil, the A/C can’t expel enough heat from the system and it’s forced to run constantly trying to cool your space. The increased pressure and temperature can cause the compressor to overheat and fail. If your compressor’s bearing goes bad, your engine can seize due to the stuck compressor.
Hope this helps!
-BDP
i filled the a/c gas and it was leaked within 5 days and the mechanic says that the leak is from evaporator. Is this can be repaired by red angle.
Shankar-
Yes, the Red Angel A/C Refrigerant Stop Leak would be able to seal a leaking evaporator. Based on your description, you would be a good candidate for the product.
Thank you!

I put in a can of stop leak of the earlier variety–reacts with moisture. Now that I have read about the oil-based system I would like to remove what I have in the system and properly service it with refrigerant and an oil=based sealant. However, I have several questions. At this point, can I fully remove the old stop leak, or should I replace components? Will a system evacuation sufficiently remove the old stop leak? If not, is there anything I can do, short of component replacement, to remove the effect of the old stop leak? Thank you very much.
Roger-
You should be able to flush the a/c system at this point and fully remove the stop leak you previously used. You would want to replace any non flushable components. Feel free to contact our technical support line at 888-863-0426 with any other questions.

I have a 1986 Toyota Corona. Air con has previously been treated with a stop leak product. Worked great for a few years but has recently started leaking from the evaporator. There is still gas in the system but only cools a minor amount. I would like to try Red Angel. Should I have the system vacuum flushed then recharged with Red Angel and R134a gas or just go ahead and add Red Angel to the system.
Jeremy-
Thank you for asking about your Toyota Corona. It would be best to use the Red Angel A/C Refrigerant Stop Leak when the system is evacuated. Add the Red Angel and then top the system off with the appropriate amount of refrigerant get it up to the proper level, letting the vehicle run for an additional 15-20 minutes. Feel free to contact our technical support line at 888-863-0426 with any other questions.

Hello BDP,
Over two years ago my Ram 3500 Cummins started to push out less and less cold air, until after about three months no more cool air from the ac. I left the system uncharged for two years, because of too many things going on in life. Just a week ago I put in a 12Oz can of R-134A to see what would happen, and it blows cold air again, but I sense that will only be temporary, suspecting I have a slow leak somewhere and the R-134A will just slowly leak out again just like 2 years ago. Do I just add a can of BDP and then R-134A, or do I need to do anything else to the system (vacuum?) since it has been “dormant” for two years?
Marco-
Thank you for asking about your Dodge Ram 3500 Diesel. Based on your description, we’d recommend pulling a vacuum first to allow space to add the Red Angel A/C Refrigerant Stop Leak. After adding the Red Angel, fill the rest of the system up with R-134A until you are at the proper level, and allow the vehicle to run an additional 15-20 minutes to allow for everything to circulate.
Thank you!

I used a can of the aerosol I’m my ‘95 Suburban that has front and rear air. Your product worked for about 24 hours. Due to the amount of lines, 2 evaporators, an expansion valve and orifice tube does this large system need 2 cans? The compressor is not leaking according to my sniffer. The AC was blowing out at 50 degrees yesterday after topping off the 134a. Today it only blew our air at 80 degrees. Evaporator before I put red angel in triggered the sniffer. Do I need to add 2 cans to this system and us it safe for the system to have two cans? WHMac
Bill-
Thank you for asking about your Chevy Suburban. One can of the Red Angel A/C Refrigerant Stop Leak would treat up to a 5 lb capacity. Please contact our technical support line at 888-863-0426 for further assistance.

Does it work with R1234yf systems ? Your post says it works with new environmentally safe systems, but you later say it designed only for R134
Gary-
The Red Angel A/C Stop Leak (2 oz. bottle, #49496) is safe and compatible to use with the new R-1234yf systems. The Red Angel A/C Refrigerant Stop Leak (4.5 oz. can, #00222) contains a partial charge of R-134a and is specifically intended for those systems. Hope this helps!

Hello first time using Angel AC leak 2oz and it’s successful sealed my evaporator leak. But after a month I visit technician to add little Freon gas on my system because I know some of the charge leak when the time my leak cure. But the technician use a vaccum to remove old freon, now system not adding proper freon I don’t know why. My question is the red angel removed from my system when they vacuum it?
Hello if technician use a vacuum is the red angel will remove from my system?
James-
No, drawing a vacuumm on the system would not remove the Red Angel or influence the seal that the product created. Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.
