- Always use caution when attempting to work on your car, especially the AC system. If you aren't fully confident in doing the work, take it to a professional.
Buy cans without "self-sealer" and with zero added oil. Self sealer will gum up the system and having too much oil in the system will make it not operate properly.
Here's some links for R134a refrigerant:
Full kit: amzn.to/40bN5xo
Two smaller cans with gauge: amzn.to/3mVza01
Just the refrigerant: amzn.to/3Lyiwhn
Here's some links for items I generally use:

For those of you asking and commenting, I'll pin this.
Buy cans without "self-sealer" and with zero added oil. Self sealer will gum up the system and having too much oil in the system will make it not operate properly.
This method can temporarily fix your cooling issues. If you have to add refrigerant, you have a leak somewhere. So take it to a shop and have them fix the leak. They'll add UV dye to the system and locate the leak.
Outside temperature does matter with how much refrigerant you'll need to add. Since I'm keeping this short, a quick Google search on "Automotive Refrigerant Pressure Charts" will have the info you need.
If your gauge is in the yellow or red, there's an issue. This will at least tell you something is wrong and you'll need to take it to a professional to have it fixed properly.
Since TH-cam took away the ability to link products in Shorts, I cannot add links that'll take you to the products I used.
Thanks for watching and commenting, I'll catch you all on the next ride!
Do you need to stop the vehicle before taking off the compressor
Another good reason to not buy any refrigerant that says self sealant is most mechanic shops won't be able to fix it, they'll force you to buy a whole new AC unit setup and that can be expensive. If you're not sure if you have a leak then buy refrigerant with uv dye, and use a uv light on the hoses to check for leaks. That won't cause any issues with a mechanic shop

Bro you made it soooo much easier then the rest of the people on TH-cam
Much appreciated! That's my main goal 😉
I work at Walmart. So a lot of customers recharge their AC in the parking lot. So as I was walking to my car. I saw an empty Freon can with a blue line and gauge attached. So I grabbed the gauge line. Threw the empty bottle away. So now I got a gauge.
Man if you live in California, that can you threw away is $10
Can you use gauge without a can to check if I need to add?
Yep, 10 dollar deposit on those cans.
So glad you found that. Now you have a gauge that's wonderful
@@Scarecrow21 need a receipt though, and the can must be returned within 90 days, according to what i've just googled.
Everything a girl needs to know without watching a 20 minute video of a bunch of useless bs. Thank you so much!!!! I subscribed because of this knowledgeable info ❤
Glad to help out! Love the feedback! Much appreciated!!
😂😂😂
@@jonatanc7624yeah,, she had to pull out the "a girl" card out lol😂
i bet the girl thinks this is also "Useless Bullshit" if you mishandle the Freon it can get on your skin causing frost bite and if it gets in your eye you go completely blind
Honelsty bo, you need proper pressure set ups but sure.
You should be using a AC manifold gauge to get correct readings from high and low pressure lines.
my dads an old school mechanic he never hooks up high unless doing a full vaccum refill but not for quick little recharges
Way to keep it simple and to the point. Great video!
Thanks for the video and I'm glad you said recommended refrigerant because I still have an old freon bottle that still looks good that I wanted to use but now I will just get what the manual calls for.
It worked for about a month and blow warm again that was 4 yrs ago I’m trying to fix it again I did without air this Texas heat not playin I’m gonna get me a black light and make sure I don’t have a leak great video 👍
Texas heat is awful! Hope you found the leak!
Remember when the walmart brand freon was 4.44 ...... now its 9.88 or something like that
Bad kitty
Just bought it for $50
Remember, vote Democrat so we can pay $100 a can. 😂😂😂😂
Lets go Brandon

@@hayd3238Yeah, same
It used to be $2.88
THANK YOU , WELL DONE . . Just watched the most difficult how to video, on this subject that I have ever seen in my life. Your video was very clear and instructive , thank you very much definitely will be subscribing.. 💯💯💯
Thank you! Glad it helped! If you have any suggestions on a video you'd like to see, let me know and I'll try to make it!
I know exactly what video you watched lol
Yeah the reason they are long is because they give you proper information this vid won't fix your AC if it was empty in the first place it's probably leaking so within 2 it won't work anymore
You forgot to add that you should not get a can that says self-sealing.
Why?
@@needs_more_dakka5774it’s because it’ll contain a substance that can block flow thru the pipes and in the long run (or a couple of weeks) it can cause AC flow to be bad snd add gunk and break down the inside of it
They cause blockages and are the reason my system is toast
If there is a leak in the system and you fill it up without vacuuming down the system and removing moisture you can destroy critical components.
this is specifically for ones that still blow cold but not ice cold like usual. if its leaking it would have emptied out within a week max.
@@uzileopard6199 depends on the leak . Could take a couple of weeks
My leak is very slow takes a few months
My leak has taken a year...It's in the hose. Slow
On my Subaru the low side is clearly marked but it is on the smaller line not the larger one make sure to not fill on the high side.
This will only help you if your ac still blows cold but not super cold as he said. As an Autozone store manager I can’t tell you how many people come back upset because topping it off didn’t help or they put too much in
So what do you recommend? I bought my car without it having air. So I don't really know if it leaks dye, or what. I just know my heat gets Hella hot, but when on air, it doesn't blow cold.
@@snowblo1 Compressor could be dirty or shot. Thermostat can cause that too, even blend door. Best course is to have a professional take a look before just throwing money at it. The AC system is alot more complex than people think.
@@snowblo1Recover (remove) all of the refrigerant from the system, pull a vacuum on the system for 45 mins to an hour to remove moisture and contaminants, then hold the vacuum with the valves closed. If vacuum drops after leaving it for 30 mins or more you have a leak, then you would act accordingly to fix the leak
Just go to a real mechanic @@snowblo1
How do you release some of the freon ?
What's the ambient temperature so that the gauge reading is accurate? This is a very serious factor to avoid damage of overfilling!
What should the ambient temperature be?
I have a 2001 Ford crown Vic police interceptor. A neighbor of mine claims that he checked the AC unit for me he was not truthful and honest about what I needed because he wanted my car very badly and I refuse to sell it to him so I had taken my car to another mechanic and that mechanic told me it looks like somebody was trying to sabotage your car. I found out that I need a new spark plugs and coil wires so I purchased all that the guy repaired it plus he had to clean my battery redo my cables on the battery also there were screws missing from under the hood add this guy had told me someone's trying to sabotage your car. I also found out through watching videos for the AC unit this guy not only tried to sabotage my car because he wanted it he didn't have the correct gauges to check my AC unit. Well sadly this man had passed away just a few months ago and I found out that he acted like he knew how to repair people's vehicles and there has been a few people that came back to this guy and wanted their money back because he never finished the job.
It was a drizzly Saturday morning when I popped open the trunk of my car, expecting to find nothing more than the usual clutter. But instead of old jumper cables and an expired first aid kit, my eyes fell on a bright orange bowling ball nestled between a stack of emergency flares and a spare tire. I blinked in surprise, wondering how it had ended up there.
As I picked it up, my curiosity was piqued. It was heavier than I expected and felt solid in my hands. I rolled it around, examining its glossy surface and wondering if someone had mistakenly left it in my trunk. The bowling ball seemed so out of place that it might have been a sign.
That’s when I noticed an old, faded manual wedged beneath it. I flipped through the pages, half-expecting it to be a forgotten rulebook for a game I had never played. Instead, I discovered it was an instructional guide titled “Rebuilding Your Engine with Simple Tools.” My first thought was that it was a quirky coincidence. I had recently been having trouble with my car’s engine, and here was a manual that seemed to offer just the right guidance. I decided to give it a read.
The manual was filled with diagrams and step-by-step instructions, surprisingly easy to follow. I realized it had been published by a DIY enthusiast who had a knack for making complex tasks accessible to novices. Intrigued, I decided to take a leap of faith and tackle the engine repair.
I spent the next few days gathering the necessary tools and parts from local auto shops, all while using the manual as my guide. I wasn’t entirely sure what I was doing, but I followed each step meticulously, driven by a newfound determination. The orange bowling ball, with its cheerful color, became an unexpected symbol of my growing confidence.
I began by removing the car’s old engine components, following the manual’s detailed instructions. The bowling ball, now an emblem of my journey, sat nearby on a workbench. I found its presence oddly comforting-like a quirky mascot cheering me on.
As I reassembled the engine, I could almost feel the manual’s enthusiasm guiding my hands. Each part clicked into place, and I meticulously followed the steps for recalibration and adjustments. It was a slow and careful process, but with each small success, I felt more capable.
Finally, the engine was ready. I turned the key, my heart pounding with anticipation. The engine roared to life, a powerful and reassuring sound that filled the garage. I couldn’t help but laugh with relief and joy, amazed that I had managed to accomplish something I never thought possible.
That evening, as I looked at the gleaming engine under the hood, I glanced back at the orange bowling ball resting on the workbench. It had been a strange and serendipitous catalyst for my learning experience. The manual, the ball, and my perseverance had all come together to create something extraordinary.
In the end, the bowling ball had done more than just amuse me; it had led me on a journey of discovery and accomplishment. And as I drove away in my freshly repaired car, I couldn’t help but smile at the thought of how a simple object had transformed into a symbol of my unexpected triumph.

Thanks straight to the point
Excellent video. Clear , concise and to the point.
You need to read the specific pressure setting for your particular car and also add the freon based on the temperature outside. Its not as simple as this video shows.
Thanks 👍
Thanks.
Actually if it is 85 ° outside it requires you to have 45 to 55 PSI 35 is for lower temps out side
I have that same Guage and mine is at about 46/47 which is in the alert. It feels like it's not blowing as cold as it should 🤔
Love these keep going my man 👍
I accidentally left the can in my very hot car for 6 hrs, is it ruined ? My friend said it has to stay at room temperature. Thanks for the videos
Do you not need to purge your filler line to get the air out before filling low line?
For some vehicles, little to no coolant can also cause an ac to blow warm. I appreciate the short nonetheless
That’s correct my friend, an overheating engine can cause excessive heat in the engine compartment and can then there’s a lot of heat up front by the condenser and also the computer can decide to shut off the compressor as well if it detects a high pressure situation. And yea these shorts showing people how to use these cans is a crime lol, they will damage the compressor and plug up the system
Great job. Nice and easy.
There's instructions on the refill can. You described the process correctly. 👍🏻
Thanks brotha!!
I wish! No longer can get it in Washington state 😢
Why?
Question that’s what did but my gauge still reads zero I also take out the fan, and just have it connected to the ac and reads 0 but when I connect the can to the hose it goes up to red
If your clutch is not engaging it will start at Red you either need new freon in the system so the clutch will engage, or you need a new compressor
Ac systems are completely sealed and don’t leak unless something is wrong you should never have to top off your ac system.
I’m getting weak cool air, not warm air. If I turn AC full blast I’m getting even weaker cool air. Is that a leak? I keep seeing people say thií about it being closed system which it is, so why do I see mechanics recharging freon to cars who haven’t had system leaks??
I was informed the ac system loses refrigerant between 10-20% a year 👍
Should be checking for leaks ,I believe you're supposed to evacuate the line to 0 pressure then fill it with pure freon to the right level,
All 🚘 compressors have a bearing that is fitted on the shaft this is the area that you will slowly loose your refrigerant its not a perfect seal otherwise it would bind up it needs to spin
@@jonschwartz9669 "loose your refrigerant" ... Is that the new English they are using these days? I always thought you "lose" something. Loose is something that is not tight.
Do I have to add oil too? And how do I know if the can is empty?
I saw other video that was 20 mins and couldn’t understand 😅 this one is the best
Thank you!!
What do you do if can is not finished.. ?
It's not a good idea to "top off"
Empty from last year and refill from completely empty to green (or in your case blue. My gauge is yellow green and red)
What about the knob? So confused to turn it clockwise or not
Thank you. It's helpful.
Will it work on the front defroster too?
When do you want it in blue witch compressor spinning or after kicks off when it spins mine is low when it shuts off mine goes into red
On the low pressure line, only refrigerant gas is allowed. Not the liquid. You can put the refrigerant liquid through a high-pressure line before you start the engine
I think it'd be beneficial for you to look up how an AC system works before spreading false information. Thanks for watching!
I cant tell if your trolling or just absolutely clueless
I mean u should never really charge through the high, really how u can charge through the high side is u have a heating pad to warm up the big 30lb refrigerant can or if ur using a charging cylinder, with those little cans from the parts store u can only charge from the low side or suction side or return line whatever u wanna call it, if u have gauges never charge through the high side with the engine running or the pressure will get extremely high and dangerous
Sometimes the ac actuators go out..
No shit. That’s not what this videos about
@@rye_too_quick ok
How to connect is not shown.
Why do I get two separate readings? It reads low when the compressor is spinning and filled near the red when compressor stops spinning. Is that normal and which is correct?
When the compressor is engaged it is in a suction state, so the pressure is lower. When disengaged it is static pressure.
@Oscar Sosa So the accurate pressure reading is which one?
22-30 PSI compressor on, might be higher if it's hot out.
@@orxt So that reading is low with compressor on?
@@fernandocazares5925 Oscar is correct on the higher and lower pressure readings. With that said, when it's engaged and you see the lower pressure, that's mainly what you're going to pay attention to for this scenario.
If it's too low, add a little refrigerant at a time until it's in the acceptable range.
What about oil? Can you just add refriferant?
Need to purge out the air in the line before use
Does it matter what outside Temp is or anything like that?
Thank you 👍🏻
1999 Tahoe had freon filled Topped off 4 years ago.Not as cold as it should be now……compressor turns off and on about how much will I need to add???thanks
Thanks dude
Can you show how to find if there’s a leak?
Use a dye
Appreciate chu
it's not working for me the gage is on red 😢
Can I use an old guage I have to check if I need to buy a can?
Appreciate it!!!!
Going to try this
how do you know when the can is empty?
Short and simple explanation.
The gauge says it’s good and full when the car is off but then when I start my car and turn the ac on it drops all the way to empty. Then when I turn the car off it goes back up to full, what does this mean?? (95 civic)
Mine's jus at the beginning of the yellow and the air isn't as cold as it should be, isn't that just an indicator that there's too much in the system?
I just replaced the compressor, so I know there’s no freon in it.. I’m trying to recharge it, but the compressor cycles on and off.. when it reaches 40psi it shuts off, then comes back on until 40psi.. it does this like every 3secs.. because it’s not staying on, I can’t get freon into the system.. anyone have any suggestions??
Where can I get that knob from ?? To release it he air ?
Don't really work that way. If the gage reads low, there's a leak. If not, you can overfill it.
Wow i have the exact same can and the same gauge
What happens if my Guage stays at 0psi when I press the handle to let the refrigerant in it
run....system will explode any second
@@misterx4088Guess he's ☠
The low pressure line is always smaller
Put mine on stays in red but when I press the trigger it goes completely low and doesn’t goes up
Does this mean I have a leak???
I think red mean its too full and wen its too full that damages the system
It may have been over filled. Have you had it diagnosed yet?
Not serios to not vacum the system first
Don’t put too much in
Be careful, too much will have an opposite effect
Nice but, what do you do after? Blow the rest of the can into the air?
Why would you do that? You simply turn the valve off and disconnect it from your vehicle...Then save it.
Makes sense if there's some left in there, but I think many people would disconnect it just to throw out the can even so. I used a small 2oz can just to get some lube in there, and it had a self-sealing orifice. I would recommend those types to avoid the issue entirely, now that I've seen the process myself. For the first time in ~20 years.@@SlothKingGarage
This guy sounds so similar to Chris fix
WHAT AREAS SHOULD ONE LOOK FOR LEAKS❓❓
How often does your compressor cycle on and off? I have the same engine.
Not sure, maybe every 30 seconds or so?
Thank you yo
Which is filter for the air conditioner from a Nissan Versa 2015
Where do I get a gauge like that from ?
Auto Zone or Advance Auto, either one
What causes the clutch to short out when it looks fine?
Thanks ..
Could be a few things. Like a fuse blowing, low on refrigerant or the fact that it's just worn out and needs to be replaced.
Mine shows in the red pressure zone before i do anything :( gotta take it into the shop 😢
Does this product seal minor leaks as well?
They sell some that does have leak sealer, but I do not recommend that. You're better off getting the leak repaired since it's going to most likely just be an o-ring that's bad
What if its in yellow or red
Is it bad to have a missing valve cap?
It's not the end of the world, but you should get a cap for it to keep debris out of the valve area. Before attaching a hose to it, clean the area so you don't get any debris in the AC system
What if you change evaporator and system is empty. Do you need to add oil ?
You will, since there will be some residual oil in it when it's removed. It could be up to an ounce or a little more. I can't give a proper amount as it depends on the size of said evaporator. Usually the shop manual for the vehicle will list a ballpark amount to add
Found all of this very helpful but when I put the coupler on the low pressure valve and start filling it spews coolant like it's a bad fit. Is that okay? I don't want to waste half the coolant and have to buy more.
Hmm that's not supposed to do that. It's supposed to lock on there, did you hear a click when you put the coupler on?
These just need to be outlawed.
I want this gauge ppz send me Link
How do I know when it’s full?
Blue line
Thanks for your help and remember that God loves you 🙂
The pressure, in terms of being in the blue, depends greatly on the ambient air temperature. If it's 90+ degrees outside you need to go as high as 55psi.
Chris fix
The issue with this, is that you're putting whatever trapped air that's inside the hose into the AC system. Mind you an AC System needs to be purged from air before introducing new freon into it. Otherwise, this method not good in the long term
You got the sub
What’s the huge problem if it’s in the red?
The system is overcharged and could cause problems with the compressor and other AC components
There's a lot more to air conditioning then just shoving refrigerant in it.
Well he did say if it doesn't work it's probably a more serious problem
Not to mention that refrigerant is not a fuel. It doesn't get used up by A/C over time. If your system is low on refrigerant, it has leaked out and will continue to do so until the leak is corrected.
Also ac is closed system if it anit blowing cold you got a leak
I keep seeing people say this, so why do I see mechanics recharging freon to cars who haven’t had system leaks??
Ya didn't show how to hook the can up. Is it just screw/unscrew?
Yeah I didn't show it because it'll just screw on
I know this is 2024 we back in the 80s used hot tap water drop your can in it whilst obviously connected to the manifold took less than a minute to empty just saying to top off ok your method is different we were servicing a empty system plus we worked flat rate
I keep seeing to put it on recirculation before recharging but my lever is broken. I took the panel face off hoping to manually switch it but it won't move. What happens if i recharge and it isn't on recirculate?
It'll be fine if you can't. The temps won't get as cold because it's allowing some outside air to enter the cabin. The compressor also won't be engaged 100% of the tike either. So don't expect it to get super ice cold. Just be sure to charge it while you hear the ac compressor on.
Think of the non-recirculation option as allowing some outside fresh air in and the compressor not turning on as frequently. Which results in less cooler temps.
Now the recirculation part, you'll get cooler cabin temps since you're not letting in outside air. And the compressor is always on, further supplying cooler air.
Hope this helps!
@@SlothKingGarage thanks so much. I took the face plate off and was able to move it manually late last night so I'll be adding it today. Thanks so much for answering me. Have a beautiful day!
