NEVER Recharge Your Car's AC System Until Watching This!

Should I first use leak sealant and then charge it with refrigerant or vice versa?

Used to recharge A/Cs by pressure. Now use a machine to recharge by weight of gas. Will never go back to the old method. Get it done properly it is worth the extra bucks.

Are you sure it has a clutch, new system have a Swash Plate which makes the pump constantly variable 0 to 100% not on off with a clutch

very informative and detailed , thank you

God bless you too

I was told by mechanic that you want to bleed the air out of the hose before recharging your A/C 😮

When you hook hose up will it tell you if it's full or need freon before you put Freon in

Good video. Acc in car is complicatec. Could be many things.

Best video ‼️

WOW, not seen a "Sight glass" since the 1980's. Didn't know some cars still had those!

Nice video gonna do mine very soon. Watched from the uk 🇬🇧

Superb video!! Thank you so much for sharing this video, i learned a lot and im about to go outside and perform everything i learned from youe video. Ill post again as soon as im done.

One should use a REAL gauge set and add the refrigerant by weight. Everything else is guessing.

cans are now self sealing and require a different access. that piercing gauge you are showing will not work with the new cans! Update your videos for the sake of newbies man!

dont do it this way folks--- evacuate your system- get the moisture out by putting your system on 30 mercury of vacuum-- use the gauges abd the vacuum pump--- your parts dealer orielly advance and autozome will lend u the tools--- do it the right way- the wrong way will be thousands of dollars in damges--- this technique is a bandaid that he is teaching,,, and never efver ever EVER EVER PUT SEALANT INTO YOUR SYSTEM... ALL SYTEMS LEAK ITS JUST THE FACT OF LIFE--- IF IT DONT HOLD THEN IT HAS TO BE PREPARED PROPERLY-- SEALANT CLOGS ORIFICESM CONDENSORERS AND GLUES THE COMPRESSOR UNTIL IT FRAGS --- THEN YOU BUYING A WHOLE NEW SYSTEM OR A NEW CAR... GO TO FOUR SEASONS AC SUPPLY faq I BELEIVE THE 6TH QUESTION ADDRESSES THIS. AND 4 SEASONS IS THE BEST SUPPLIER OF AC PARTS

Have to do this to my sister's car.God bless

There is a lot of bad information here. As for low pressure side pressure, from hearing experts they say generally , low side pressure is 1/2 ambient air temperature. So if its 90" out when adding gas low side pressure would be about 45. High side pressure 2 x ambient air temperature so at 90 degrees, high side would be up to 180 if your using a gauge set. But your car manufacturer likely gives the exact specs numbers they set per temperature. Also on purging this short line (generally with a short line like this they don't say anything about purging the line), but I believe that the can valve would need to be slightly opened just as connecting to low side to hear a hiss. Otherwise that line is open to atmosphere and will fill right back with air when valve is closed. Also, not holding can upside down. Can's says hold it 12 oclock position and shake/rotate from 12 to 3 oclock position meaning the top of the coolant gas can from straight up (12 noon to 3pm).

Great video. NO ONE talks about the details of how to hold the can- NOT held in the inverted position only- move it in a 90deg. motion. Thank you, !

Great video. Thanks

It's R-12 not A-12 and it's harder and harder to find Also there is also R-1234yf in addition to R-134A .

how do you know when the can is empty to use another can?

This is really good. Best one i think and Ive been watching a bunch of these. One thing i have to say is it seems like MY CAR is the only car around where the opening is not just sitting right up top, nice and easy, clear as day, mine is like under the freakin front wheel up inside the damn fender, like ridiculous, ill need a 20 foot hose to be able to see the gauge. Whyyyyyy??? I can't explain how literally any little thing i do seems like it is just way more difficult than it is supposed to be!!!! Waaaa waaa waaaa 👶😫😩😤 just had to vent. Ps i have a ford focus 2003.

The other refrigerate beside the 134a was R12, and it was not sold over the counter because in order to service the R12 system, you had to have a license, and it was a must-have to have a recover/recharging machine because you couldn't let this freon into the air it was illegal and could kill everyone in a shop.

Hi

Good vidio some cans tell you to keep the tap down so look out for that you will see arrows pointing the way.

Cant believe Im still watching this😂

Thank you Brother.. Your video is simple yet detailed in instruction and I really do appreciate your effort to educate us folk who have never done this before. Thank you so very much and may God almighty protect and sustain you and your family!! God bless you!!

excellent video . education without the need to go to the school to learn it. You are a mechanic teacher. God bless you too.

You are an excellent teacher, you explain the procedure so clearly, thank you. I will follow your steps. By the way, I have a 2013 Prius V, it is 11 years old to this day, and all of a sudden, the strong air coming out is not cool (cold), is this normal?

Jesus bless you brother. Thanks

Thanks I need to get a gauge because I may have over filled my system using one of those all in one systems

See how that do it yourself can has the squeeze handle/connector on top of the can.? Is it ok to just buy a small can and add the squeeze handle/connector to the small 12 ounce can? And what if it say's it's already full (in the green area) but I keep putting more in untill I'm in the yellow area?

I miss the good ol' sight glasses....
But I'd still like to see the pressure readings.

If you have air in the sight glass, how do you remove the air? Is the a/c on when you are bleeding it down?

After connecting the blue hose, there was no way to purge it of air/humidity before it entered the system?!., like with a real manifold or you loosen the connections slightly until you have some refrigerant coming out to be safe for the system.

Best Video I have EVER heard, Not a lot of talking straight to the point with excellent key points, easy to write down notes, Thank You, I am a woman, perfect video, perfect information. Easy to understand. Deb

Is it normal the clutch to engage every 10-15 seconds regardless if the AC is set or high or low? I would've thought that when on low it should take longer cycles than when AC is set on max but it does not seem to make a difference.

Amazing! Thank you so much I come back to this again and again!

What was temperature outside when you did these

That's eligal true gas in the air.

I would not recommend using this hose. There is another kind where the gauge is in the middle. On one end is a conventional can tap, and on the other end is the service port connector with its own valve. These range in length from 18 inches to 4 feet. You should buy the longer one. Pay attention to which style can tap is provided. The kind used for piercing-type cans is different from the kinds that are self-sealing.

Hi Paul...greetings from Ireland. Excellent video....many thanks

It was r12 my 1990 buick century custom 3.3 liter v6 was originally equipped with r12 but I've switched it to 134a

Thanks for the video

Well SHIT!! I NEVER knew to PURGE that shit…WERD NERD!

I take it the connectors on the supply hose are compatible with all vehicles and refrigerant cans. Universal.

I heard that if you get the high side too high, then it wont come back out. So I didnt think you can just bleed out the low side... True?

Excellent explanation!. 👍🏼👍🏼👍🏼👍🏼👍🏼

low presser , high pressure ports ,is what you mean .
