DOES A/C STOP LEAK REALLY WORK???

I have a 2013 XF and I can’t find the plug for the compressor. Any help?
Thank you.

Because who needs to pull a vacuum? SMH.

not to sound like a wisea*s, but how can you say it works? the leak continued no?

I have 1 question. If you know that there's a huge leak and 15 minutes later it would be empty, its 1.) a waste of money and 2.) Its irresponsible to let it leak into the atmosphere. I know its just testing to see if it works but it should have been tested on a small leak or atleast a leak detector to test for a leak with a recovery unit on stand-by.

Is it essential to hold the can upside down?

It works for the folks that make and sell it.

According to a garage my car had an old leaky condenser and possibly o-ring leaks around the compressor. This is after putting dye into the system, they couldn't give me any definitive but definitely wanted a lot of money from me to fix the problem for good. A can of stop leak and some more refrigerant did the job just fine and it's been over a year.

What can I do if my system doesn't hold any pressure at all? It has leaked all Freon and can't hold a thing.

I have an 07 Dodge Caliber the AC was working fine for years. Then I had to have the alternator replaced in order to do that the shop had to move the AC compressor which involved interfering with the seals on the compressor which they replaced but then AC started leaking we thought that the seal is leaking because they were aftermarket instead of OEM I replace the seals with Lem seals they got the car working with the air conditioner working yesterday said that it was putting temperature out about 45° and I paid for the car and pick it up this morning and it's not producing any cold are all he says he can't find any leaks anywhere so now he's he's saying it's probably the evaporator coil in the dash and it's going to cost like $900 to repair. I don't have that kind of money. I don't know what's involved in taking this car apart myself I'm just wondering if an ACC lore is an option for me it took approximately all night to lose the ac refrigerant which is about right for the car it would sit overnight and lose the refrigerant I'm wondering if an AC stop leak component has any chance of fixing this or am I just screwed and have to replace the AC evaporator thing in dash

There are generally two types of AC stop leaks. One is essentially just PAG oil and the other type reacts to moisture, theoretically at the pin hole leak. The PAG oil types will only work for minor rubber o-ring seal leaks. The latter will work for leaks in metal. If you use the latter type, you will need to vacuum the system (to boil out moisture), otherwise you will clog your AC dryer, or worse, accum/conden/orifice. Adding more and more stop leak with PAG will cause harm if done too many times.

You might want to view the manuf's method for adding R134a. I do not know of a case where you need to turn on your condenser. Adding on the low side will bring up the pressure to satisfy the pressure switch (add vapor/not liquid). Your manuf service manual can verify if this is the case for your vehicle. I believe in some vehicles it would be best not to jumper and run the system dry.

Also add with gauges or by weight. Weight method is the best if you can reclaim the R134A or if the system is empty. Gauge method is good if you are a little low.

You can rent (free) a gauge set and a vacuum pump at your local parts store and do the job correctly. There are a ton of videos showing how to use them correctly with no guessing.

It will take time to tell if a stop leak "hail mary" worked. You cannot tell if it worked by running over short period of time. No stop leak will work for a system that leaks out over a period of a couple of hours. It is best used for a system that has a much slower leak.

The best thing to do is to add some dye and verify where the leak is. If it is in the pump or condenser it is an easy enough job to replace o-rings or even the condenser/pump if aftermarket parts are used. If it is in the accum then it is not an easy fix. You cannot usually view a accum leak because it is buried in the dash, but you can see the dye in the condensation drips on the ground.

no they dont ,,, waist of money ,,,, very very very rare if it does 99.9 percent chance it wont work

It is not a freon

That MacGyver staple move was nice!

i had a slow leak in my truck and put some oreily blue devil stop leak and it fixed it for 3 summers. Before i had to recharged every summer.

It's slowed it down for me but it doesn't "seal" things up

Dude u said it didn't work then u say it works. Lol it doesn't work

I was told that stop leak can destroy compressor...I believe this is a blind try...I'm getting ready to repair my ac in my 99 chevy express...I have manifold gages,vac pump...years ago my friend owned a 98 chevy truck...what we done was put all new seals in everywhere..and lucky bingo, the system held good..so if your gonna go blind,,do it with new seals and pray

That is a very serious leak
..most cars I have had leaks lasted 6 months or more...I would add a can of stop leak to a slow leak maybe,but for this leak I would have added die to locate all leaks and replace parts and seals than recharge..great demo on product. Thanks

Stop leak works great for SMALL leaks like old hoses and cracks in the condenser soldering but large leaks as stated on the container requires part replacement. But the stuff works is the point here. It’s not snake oil but not a magic wand either lol.

Depends where the leak is,if it's o rings or gaskets or maybe rubber hoses, that stop leak MAY work but if it's a metal line or condenser, evaporator leak,you need a stop leak that will stop a metal leak, though those types of stop leak will eventually clog the system but .!

Of it all leaks or up within about two weeks or less to need to make physical repairs like o-rings etc.. no leak sealer well fix that.. is only for very small leaks. Line in my car where the gas leaks or over two years.

Why did you put three different gas. And how did you put all at once?

Question : So for the last can . How do you know how much you are adding ?

I been doubtful since my fereon leaked in about a month or 2, and that's aggressive in my book. My dad had creasida 1991 and had to refill it's fereon only twice in 25 years of using it.
Just put one 30 mo Italian stop leak and hoping this works man.. I have been let down my Toyota. It was the best once upon a time.

Sure would hate to fix it right. You should try transmission rebuild in a bottle next.

Did you let it run during the wait times (15 mins & 1 hour)?

Never turn freon bottle upside down when charging you are putting liquid in it and can knock your compressor out

Good info thanks

Hopefully you see this and can reply. I have a leak on mine and put some refrigerant with UV dye in it and only place as if now I see glowing is the vents inside at dash. What would that be if so??

I can confirm it works on a small leak not big leaks. It fixed my 18 year old car that had a small leak

Toyota's seem to have the most durable ac systems. I've seen 25 year old Toyota's in Florida with all original systems and one recharge in 25 years 😎

compressor jammed after 20 minutes ... 2000 USD of damages and 8 hours of work to fix everything ...

no, they are scam products! They clog your compressor and the expansion valve. These products are the shortcut to a complete failure of the a/c system.

It sounds like it didn't work in this case. Maybe for a smaller leak.

I was super surprised with the supertech AC stop leak. It worked and I had a little more than usual leak. For the price, it's a steal and works.

How do i get this product am in Nigeria

how about that pretty aggressive camshaft?

DO NOT USE STOP LEAK

I have a slow leak in a 2000 Silverado. Blows cold for a few days. Just ordered the above spot leak. Will report back in a few weeks.

It doesn't work not even with a pinhole there are videos you can watch find a leak and solder it

You did not have to use the staple just add a little bit of freon and the compressor will kick in. Then you can do procedures with the rest

will it damage the new compressor i installed if i try to run it and spray it with soapy water. Before taking it to get re-gassed?

A week and it drains out? I would say it's a waste of money and doesn't work.

How can I get same of the stop leak,am in Ghana

I always read (can't cite the source...too long ago) that you should not invert the containers which dumps liquid refrigerant into the system causing "temperature shock", or sending non compressable liquid straight to the compressor. Any thoughts?

I like this guy's video because he tells it as it is.
Today, after 2 years of putting up with no AC, I used proper gauges to fill the system with pure gas, no sealer.
A garage, 2 years ago, told me a new compressor was needed (leaks between moving seals).
So I'll see what happens. It might leak out in 15 minutes. If so, I probably need a new compressor and other seals.
However, if it lasts longer I know it's a slow leak, like a slow puncture that can be topped up.
BTW can "stopleak" totally ruin the car's AC system?.

That shit don’t work never does

So if my clutch is spinning then the compressor is working? My clutch spins with the ac turned on or off

What’s the plastic Walmart gauge for?
