Using my manifold set- I'm recharging through the low Port ONLY- the low Port coupling is obviously open. My question is-your highport coupling is open so this way you can READ the pressure on the manifold gauge... The High valve on the manifold gauge NEEDS to be closed...BUT the coupling on the high side is OPEN for reading on the manifold gauge? Is that last part correct??

Close the big red knob before connecting the refrigerant in fact, close both knobs ( blue and Red low|high ) before connecting the yellow service line to the refrigerant. open the blue knob after you bleed the yellow line of air and open that knob only at the manifold and very slowly.

I recommend you plan out a step by step procedure and follow it carefully and try to limit distractions while you preform the job. If I would have done something like that I wouldn’t have had to buy that compressor. Good luck my friend.

I know that it’s taught about the efficiency of liquid charging, but few people know that it also builds head pressure very quickly, and has, on more than one occasion, damaged compressors, and even blown up discharge hoses. If I’m not being paid by the hour to do it, I am more than content to babysit the damn thing and gas charge, then, there is little to no chance of slugging the compressor. Unless the system is a walk-in cooler or something, the time saved by liquid charging is really not worth the damage it could do. I will say that I have learned some things from this video, however. Keep up the good work of making sure that people out there realize the potential they have to hurt themselves if they don’t do this correctly.

We say turn the bottle upside down because we "crack" the valve open where it is released as a GAS not liquid in the gauge set, and again once it enters the system. You can do it either way. Also leave the high side valve closed when vacuuming down, it wont vacuum faster with the valve open, it equalizes through the orifice or expansion valve, no problem.

For everyone asking "Why is there a high side valve if we don't open it?!" It is there to vacuum it down the system a little quicker. The reason I said don't open it is the system is a loop and just vacuuming via the low side will accomplish the same goal a bit slower. BUT if you forget to close the high side when you turn the car on with the keg attached the system pressurizes with the valve open it back feeds into the refrigerant keg and explodes most likely injuring if not killing you. Good? Good. ALSO You don't need to add any in this instance because nearly zero is lost. If you put too much oil in the system won't work at all and is very easy to do. If pag oil was important in this instance I would have mentioned it. -Ryan

I followed your video to the letter, including NOT opening the high-side manifold gauge. I ran vacuum tests for 30 minutes, waited 10 minutes, and perfect -- no leaks! So I proceeded to load freon, and the same thing happened the last two days: within 30 seconds after beginning to add freon, the high pressure switch on the back of the compressor blew out! I assumed it happened yesterday because I had not properly installed the split ring to hold the high-pressure switch in place, so I carefully checked to ensure the split ring was installed properly. Today, the same thing happened again -- within 30 seconds there was a loud hissing, then a 'pop', and the high pressure switch had blown out again.

Really good explanation. You mention a “ AC leak sniffer “ as one method to find an AC leak. I believe another one is to install a “ dye “ in the system. The negative about this method is you put it in, charge 5he system, drive around for a few days / weeks and then using a UV? Light in a dark area to look for the dye. . Then you pretty much evacuate the R 134a, replace the part / parts and then follow your steps from this video. Toyota charged me $175 to look for the problem on my 2017 Highlander when it was blowing “ coolish “ but nowhere near cool air back in 2021. Everything worked fine but the problem returned less than 2 years later. My understanding is that a very common Toyota issue is the AC flow pressure???? valve stops working. To replace it you must evacuate the “ Freon “. Toyota doesn’t even sell the valve they want to sell you the whole compressor which includes the new valve. They do this on a lot of repairs. If I paid $175 to have my AC repaired in 2021 for 20 months I imagine it would cost over $300 now. Buying this “ kit” is cheaper than that by far.

Hey there, when pulling a vacuum on a system, it means to remove air or moisture out of the system. As you can imagine, air and moisture exist in a "vapor" state. The Low side of the system is vapor only, while the high side of the system is liquid only. Therefore, you don't have a need to open the high side if you're not working with the high side. Hope this helped!

The blue gauge is also cut off from your car AC. So how does that prove that your car AC lines and fittings are not leaking ? All what you have done is to show that the valves at you manifold and the yellow line to the vacuum pump is not leaking but you have not shown that your car AC lines and fittings are not leaking !

@2carpros isn't wrong about they process, but it's not the only way. If you follow the steps in this video, you will be ok. But, he is completely wrong about his aerosol logic. Hairspray and A/C do not get cold for the same reasons... at all. Hairspray (and most other aerosols) feel cold on the skin from the process of Evaporation on your skin, after the atomized mist falls out of suspension... Not the pressure change from leaving the can. It's actually the can that loses heat in that process. Remember... Water from a hose feels cold when it's misted over you & it's not high pressure. It's the extremely small size of the droplets, they can't hold heat. Recap: liquid atomized into a fine mist - rapidly loses heat. That Mist falls out of suspension (lands on you) & turns to a thin layer of liquid on the skin - the evaporation process begins. Additionally, the air going across that thin layer of moisture also removes heat - The cold feeling on your skin. This is why we sweat, not how our ac system works.

@@NemonicsRacing this is 9 months old and I'm not even really watching his thing but... While you're absolutely correct about the evaporation of the things leaving an aerosol can, landing on your skin and then evaporating.... A can contains pressurized gas. Sometimes it's even pressurized enough to be liquid within the can. When you expel those out to the atmospheric temperatures that can itself gets cold, for the same phase change reason as your air conditioning system. The best aerosol can example of this is actually the AC cans themselves when you go to recharge the system. The reason they get cold as you're feeding it into the low side of the AC system is that they're going from highly pressurized into a liquid, and phase changing to a gas. So while nothing you said is wrong. Nothing he said is wrong either. You just misunderstood what he said.

Great video. Good information. But I have to say, its enormously frustrating to watch 10 different videos on the same subject, and each one contradicts the other on some aspects. For example, some respectable videos will tell you DON'T turn the refrigerant upside down to force it out as a liquid because it can shock your AC and damage your compressor, which is designed to compress gas. Others will says alternate rotating the canister up and down so that you putting in refrigerant in both liquid and gas form, but not so much that it will hurt the system. Still others, like this guy, are telling people just to dump it all in as a liquid to speed up the fill, with no regard to any potential damage, just to save time. Hard to know what to do when newbies get such wildly conflicting information about the "right" way to do something like this.

@Grrrnthumb Жыл бұрын
Notice the guys saying not turn upside down are DIYers. The pros know that the whole point of a compressor is to turn liquid into a gas. It ALWAYS has liquid coming in to because it is in the loop after the condenser which converts the gas to liquid in order to get the cooling effect. So of course the compressor can handle liquid. Google image search for car AC diagram to verify this is true.

You lost half your vacuum when you connected the high side line. Should have added some refrigerant first, then messed around with the high side. Always break the vacuum will refrigerant before you do something that will lose it.

Ok, so, do what he did in the video, but add a can of refrigerant before connecting high to prevent vac leakage?
@MartyMitchell92660Ай бұрын
@@ShyRage1 Correct. Break the vacuum with refrigerant. You want positive pressure in the system so when you make a connection, refrigerant will come out rather than air going in (not good).

Some systems won't leak while under a vacuum test however, once the system is charged and the compressor is making a LOT of pressure it 'may' leak.

Pressurize nitrogen at 250 lbs into the empty a/c system checking for leaks with Windex or bubble blowing solution . Always use eye goggles and face mask . Inject Pag oil into the system on the high side then close valve . Very good and concisely done .

Liquid charging to the high side of the compressor is faster, mind you it is also risky for a novice, for if to much is fed in too fast you run the risk of blowing your nice new compressor if you just replaced it, it's for this reason I would recommend charging your unit with gas to the low side. This is how I was taught and it never failed me nor a compressor yet ! TY Sir, all and all an excellent video ! 😎✌️✝️💕🇺🇲🦅

Nice. I have some step by step instructions from 2006 for vacuuming and charging the AC system. It differs slightly from what you say. First, it says to open both valves when vacuuming and 2) it says to "flood" the system with liquid via the high side until it takes no more after vacuum is complete. This should only be done during pre-charge (i.e. after vacuuming and before adding refrigerant via the low pressure side port) and then close the red valve. Next to make adding refrigerant faster to jumper the AC cycling switch (if possible but not necessary) to force the compressor on (in my case jumped the AC cycling switch on my Cobra and Ranger) and add refrigerant via the low pressure side. At this point you don't want to open the red valve while charging the system. I used this method to convert my 95 Cobra and 94 Ranger from R12 to R-134a without issue (i.e. pre-charged via high pressure side). Is the way you present charging the new school method?

Try collision repair shop as they have the ac recovery machine but aren't in business to make money with it. 3. Don't go to a corporate chain; local small business will be more likely to work outside the box.
