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

@@janenutt4233 No.........

Much appreciated! That's my main goal 😉

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.

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.

my dads an old school mechanic he never hooks up high unless doing a full vaccum refill but not for quick little recharges

Texas heat is awful! Hope you found the leak!

Just bought it for $50

Remember, vote Democrat so we can pay $100 a can. 😂😂😂😂

Lets go Brandon 2024 Trump

​@@hayd3238Yeah, same

It used to be $2.88

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

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

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

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 should the ambient temperature be?

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.

@@kairaiuakc😂

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 🤔

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

Why?

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

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.

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

No shit. That’s not what this videos about

@@rye_too_quick ok

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.

Use a dye

run....system will explode any second

​@@misterx4088Guess he's ☠

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?

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

Not sure, maybe every 30 seconds or so?

Auto Zone or Advance Auto, either one

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.

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

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

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

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?

Blue line

The system is overcharged and could cause problems with the compressor and other AC components

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.

I keep seeing people say this, so why do I see mechanics recharging freon to cars who haven’t had system leaks??

Yeah I didn't show it because it'll just screw on

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!
