Thanks for the video and specially for the clarification about pump oil and AC oil just bought a pump and came with that oil I really thought using that oil for Ac
Hello friend Im hoping you can help me 🙏🙏 I watched you video and followed precisly your methods but when I jumped the clutch and tried to get the refrigerant in it would not take in the refrigerant 😪 I worked one it allay even re vacuumed the system and redid the entire proceed but it would not suck in the refrigerant.. what am i not doing rite?? any help or guidance is very much appreciated 🙏🙏
Yep, and the video poster clearly keeps tapping the threaded portion of the fitting indicating that it's the threads that need taping and this is patent nonsense (just like all the idiot plumbers out there who insist on clarting compression fitting threads with tape, too!

Hello my name is Bill from Medford Southern Oregon this guy is absolute telling you the truth this the way you do it 12 years I'm in AC so I know he's right yeah yeah kudos kudos brother
This guy should have 1 million subscribers already. Your video was so descriptive I feel confident pulling a vacuum and recharging my air conditioning system. Thank you for taking the time to list the items in the video with links. You are the man!
After watching a number of videos, you are the first to tell me that when I am drawing a vacuum, I do not draw off the PAG oil. THANK YOU. I evacuated my system (during the removal of the secondary rear HVAC unit) and wanted to know if I needed to put more oil in the front system during recharging. I bought the vacuum pump as well as the gauges and pulled the vacuum to test for system integrity and extended the vacuum time to ensure complete removal of water (since the system had been opened when ancillary pipes were removed).
I'm glad it was useful! :) Yeah, many of the videos on here kinda suck, or at least, don't go into too much detail, so that's why I decided to make my own! Glad you liked it!
I disagree. Oil CAN be drawn out of system .Professional A/C machines have oil reservoir than need to to be drained. Where does that oil come from? Your system I suppose.
I've been watching videos on this topic ALL DAY while I've been working on this vehicle and this video is BY FAR, the clearest, most informative and concise one. Many thanks Cheers
Nice work! And you included the critical step of purging the air from the service line (yellow hose) and how to deal with the compressor that won't kick on due to the low pressure switch. Bravo.
would air still be in the low side line of gauge still after purging service line or is that small amount expected. also love the content and Russel brand sound.
The low side line is under a vacuum with the rest of the ac system; there should not be any air/moisture in the low side line while purging the service line.
When you get ready to refill your system before you start the car go ahead and purge your valve after you hook your freon to your hose and then go ahead and start to refill your system your system will take the freon without the car running!! If the freon don't want to start coming out get a pan or small bucket and put hot water in it and then set the can of freon down in the hot water and it will immediately start coming out. But you can start to put at least one can in your system before you start your car and that away your compressor will come on when you start your car and that away you don't have to go messing around with relays and fuse and things like that Hope this helps

I have to thank you for all of your videos on repairing the AC system on a Saturn Vue. I have a 2006 Saturn Vue, 3.5L V6. Thanks to your videos, I was able to replace the condenser, compressor, dryer and expansion valve and vacuum/recharge my system. My AC is working better than ever! As a side note, I wish I would have found your video about replacing the scroll valve earlier. It would have saved replacing the other components. Thanks SO much again for all of your work and time with your videos. It is GREATLY appreciated out here!

Thank you!! Had to replace my ac compressor and this had everything I needed to vacuum and recharge my system to include trouble shooting potential issues and purging before recharging!! No other video I watched had those little details that are apparently extremely important. Thank you again, good sir!!
Thank you for making this excellent video. I rented a vacuum pump and gauges from AutoZone, just to draw a vacuum and verify that my system has no leaks and can be refilled. But I thought that refilling it would require some additional components. After watching this video and realizing that I have everything I need to recharge the system (except for the R134A), I am going to recharge it myself and save over $200 that the shop will charge to do the work.
Thanks for the refresher course. On a 2017 Toyota Corolla iM, I needed to jump the pins for the radiator fan relay to jump start the ac compressor which is clutchless. In the engine bay fuse box there are no diagrams on the relays, but I needed to jump the two pins closest to the front of the vehicle.
You are the man I followed your directions and it worked like a champ hopefully the charge will hold. I put new o-rings in the high and low side compressor ports on the Subaru. Supposedly it's a known failure point. The only comment I have I think that stuff looks like smoke is coming out of the vacuum pump I think that's moisture just getting sucked out of a system. I played around with it for a little while every time I introduced air into the system and then drew a vacuum on it I saw the smoke come out of the vacuum pump.
Hey buddy thank you for that video you absolutely deserve a million dollars very detailed explain everything that makes sense to the commoner and you took your time. And you showed some scenarios. That we could try to troubleshoot. but at the enf of the day. You did a h*** of a job with the video. Thanks man.
Incredible video, mate! So much attention to detail. No idea why there aren't hoards of subscribers. You wouldn't happen to be from Zimbabwe, originally, yeah?
Thanks for the kind comments! Slowly but surely getting momentum here on TH-cam. It's a long and painstaking process, but maybe i'll get there in the end :) Never been to Zimbabwe, but I have fancied visiting South Africa; I was going to go this year
@8:16 you left the cap on the vacuum pump exhaust while it was running. Isn't that bad? Also, my vacuum pump is very similar, and the manual says to take the cap off the oil inlet while it runs.
Well great step by step slow pace video for us 101 rookies lol... So now I know how to charge it back !!!!! I will now look for your extraction video process, hopefully it's this clear also cause it's my first time doing this and im not to confident messing with pressure tanks and machines!!! 😅 Even though I definitely do mecanic work... thakx again
I've watch 45 videos this weekend and this was my far the best, especially when using the little cans. The only difference was that you were the only one that instructed to open the high side during the vacuum cycle. But you way must be right because its working for everyone. I dont know why you shouldn't ever open the high side but it was said over and over.
Only during the Vacuum, High side Closed when Charging freon on low pressure side. The high pressure guage will still read the pressure, when valve is closed.
@@Gruindo you mean the high valve is open at the valve stem but closed on The gauge? I assume it would have to be to get pressure reading. I just ordered the kit and the high is only thing not clear to me.
Wow, great video, thumbs up! One note, at 6:04 you said to use teflon tape on the pump threads, but actually that doesn't help at all, could even make it worse. Any time your threads are on brass piece attached to a hose, and they spin independent of the hose (same as a garden hose) then the washer or o-ring or rubber seal inside the hose does 100% of the sealing. Threads do zero% of the sealing because gas/air/water could just escape out the top where the threads attach to the hose and spin separate from it. The job of the threads is only to pull tight on the seal that is already there, and adding teflon just makes it harder for the threads to do their job.
It's to do with the fitting, not the material type. (I.e. brass) IF you have a flare fitting, don't use it. Because the connector won't bottom out, and it CAN leak (Not always) IF you don't, then use it.
@@TutorialGenius Sorry, I didn't mean it depends on the brass material, only that the brass piece you hold up and show us at about 6:05 spins INDEPENDENTLY of the hose. That means you do have a flare-type fitting or similar with an internal washer that does NOT want teflon tape. It is incorrect to use teflon tape on that exact fitting as you claim. It could only make the seal worse, not better.
Under normal conditions, meaning the system is properly sealed, and the pump and gauge set are working correctly, vacuum should pull to 30” of vacuum within the first minute and hold while the pump is running. If the system doesn’t pull down to 30” of vacuum at all while the pump is running, there’s a significant leak preventing it from doing so, or there’s a problem with the pump.
many thanks! First video I have seen that explained why I couldn't get the freon in the system (I didn't know that all the way screwed in AND out meant the can was closed!)
I Did A/ Few A/C In Cars, I Never Used A Vacuum, I Replaced Lines, Replaced Compressors, Replaced Condensers And Evaporator Without Doing A Vacuums And Worked Good Always. Amén.
one thing to also keep in mind is to check your valves with a little spit hawk tuah. if you see bubbles take a small allen wrench and quickly press on the valve to reset the valve seat. probably one of the most overlooked leaks on ac systems
You don't need to bypass the AC relay to jumpstart your compressor. The pressure switch on the high side line prevented the compressor to run because it has both minimum and maximum pressure required in order to run the compressor. Neither too low nor too high on pressure isn't gonna start the compressor. I only saw +/-50psi on your lowside, I say you need to get at least 70psi and then you don't need to bypass or force the compressor to start. Works well. Hope that helps!
It is clear tutorial... thank you . I have a question... For Honda Accord 2008 - 2012... because the condenser come with the receiver drier assembled into one. How much we need to add the PAG oil.... when we replace the condenser that come with the receiver drier . If you do not know a specific amount, in general how much usually AC technician add it.. thank you.
I have a doubt, please help me with that. I could see you did vacuum in both lines low and high but when you added the ac refrigerant you only opened the blue valve and my question is: the hight pressure line don't need to be filled with ac refrigerant? Or only the low pressure line has to be filled with ac refrigerant? Appreciate you can helo to resolve my doubt. Hi from Honduras....
I finally figured it out, some of the fittings had loosened up. I’ll leave this so that others might see it!! Thanks again A new subscriber, very good info. I have done all steps to pull a vacuum and when I open up the dial on the gauges manifold I get no sound change on the pump nor do I get any read like you do get to 30 , I get 0. Any thoughts would be appreciated!!!
@@TutorialGeniusDid my Caravan without incident yesterday. Last night my son brought over his CRV. Even jumping relay, I eventually” noticed the condenser fan fuse was out (clutch required this as well). Once replaced, we were done in 15-20 minutes. I’ve wrenched on cars 40 years, and wouldn’t have thought of forcing clutch. Many thanks again. 👍😎😎
Hello. This is a useful video, thanks. I just have a question: the vacuum pump sucks the oil too, or the oil remains inside the compressor and A/C system? Thank You. Have a great day.
I know I’m late, but is that one of those special Honda/gm Saturns? That looks an awful lot like a j series Honda v6. If so super cool, and also, very informative video!!!!!! I’m a commercial tech for reefer and diesel apu’s. Your video is awesome! I needed to re look up my knowledge on cars as I need to recharge mine and my wife’s. Your video was great.
Does the oil poured into the compressor circulate throughout the system or do you need to put oil in the lines, dryer, condenser, evaporator separately?
I don’t add oil into the charge line as it will spray out when you purge your air but you can use a can of oil charge and add it to the low pressure side. I just drain and fill the compressor oil because I changed the compressor so I don’t add any oil.
No, you can't add a can of oil charge to the low pressure side this way (through the manifold gauge). I tried. Vacuum won't pull the oil up out of the can, and the hole between the yellow and blue lines is too small for the oil to get through in less than an hour.
@@philipgoetz8681 That's interesting because I just made a big boo boo. I opened the valve on the manifold gauge before i turned on my vacuum pump and the system sucked oil out of my vacuum pump. Now I have to find a way to remove all of the oil in my system as I have no idea where all the oil might have gone. I had just put new oil in my vacuum pump and after that happened it was no longer visible in the sight glass so I know it had to go in.
Great Video! When measuring the refrigerant weight for correct filling, how do you take account of the amount of refrigerant in the yellow pipe that was used to purge the pipe? Could a pipe load of refrigerant actually be quite a proportion of the specified amount, especially if it is in there as a liquid, rather than a gas, for pipe purging purposes? Or maybe the liquid refrigerant flows back into the canister under gravity before one opens the manifold to start filling, leaving only an insignificant amount of gas in the pipe? Or maybe you tare the canister once the pipe has been purged and then reconnect the canister? Also, did you purge the yellow pipe in between canisters? Thanks for any clarification given.
You don't need to worry about the pipe, I think you're over-thinking it. It's almost negligible. The psi readings will tell you the pressures in your system, so go off those. Don't add x and y and hope its okay. If you add the 'correct' amount but it's slightly low on the readings, then add some more. Yes, you should always do this: RE: "Also, did you purge the yellow pipe in between canisters?"
my gauge only went down to 25 psi on the mercury, is that normal? I have a 2008 Chrysler Town and Country and my system was emptied on the freon when I did the air bleed
Very informative and thank you. When i turned the pump on and opened the high and low Manifold Gauges, I never heard the sound of the pump changing as i opened them. Any idea why? Does that tell me that the system is not pressurized at all? AC has not worked for years and i just replaced ac compressor today.
I'm assuming the system was contaminated from the failed compressor? Did you flush the system before fitting the compressor? Otherwise, I guess if the pump holds negative pressure, I Wouldn't worry too much. If it doesn't, then there's a problem which may explain this
Your the third video that is great..i know fully understand the automobile AC system..im no longer afraid to work on my ac...my 99 chevy express, has zero freon..i shall repair my own..and save a bunch of money
Thank you for the helpful video. I have replaced the entire AC system in my 1996 C1500. New compressor, accumulator, condenser, all new switches, every thing... I followed the steps here and even jump the compressor, however, I could not get the system to take the R134A. Can you advise? Thanks!
You either wasnt under negative vaccum and wasnt able to push any in. Or your low side hose didnt press the shrader down. If you had a vaccum and it stayed under vaccum you should have sucked the can down in 3 sec
Hello friend I have the exact issue with my new condenser did everything exactly as the video and jumped the clutch but it. would not take in the refrigerant. spent allday last weekend trying to get it to take it but it would not. Did you ever find a solution or what did you do to get the system to take the refrigerant??
Where should I start trouble shooting if after I vacuumed and filled the system with freon, go the test the system and I'm in a vacuum on the low side 50 on the high side with AC set to max, warm air blowing out, 75 degrees outside.
@@TutorialGenius they are in correctly so I have a blockage. My plan is to blow compressed air through the lines, replace the filter drier and the exp valve.
Hello, I have a 2020 Toyota Corolla, I had to replace the condenser due to a leak, I have a question now when I add refrigerant, do I have to add oil to the compressor?
IMO, this is the best and easiest-to-follow tutorial on the subject, and I have watched many. Although I would like a wee bit more vocal enthusiasm. 😂 Very thorough, knowledgeable, and understandable. One thing I like to do for clarity is to photos of any manufacturer directions and add the appropriate links. And, according to Socrates, Wisdom is limited to the awareness of your own ignorance. Meaning, it is inadvisable to self-refer as a "genius." If you think you are smart, you may be overestimating your faculties. Stay humble, friend.
I'm glad it was useful If I charged $50 bucks for this content, I would accept that: RE: " I would like a wee bit more vocal enthusiasm". Sure! But, you know, it's free, right? Take it or leave it haha! I'm a straight shooter, I'll be first in line to say your comment sounds a bit entitled! My kids are the same way. It annoys the hell out of me, but im old school! We are different generations of people, but I appreciate the the inclusion of nice comments a sight to behold! Socrates once said: "Don't look a gift horse in the mouth". Or was that Plato? Who knows!
Don't you also need to add back some PAG (or similar) oil into the system after the vacuum is complete? I was under the impression that evacuating the system removed some of its critically important lubrication oil.
fine video !!!! but i have a question ! how you know how much Pag oil you removed from system if you open high pressure side too when VACCUM the system ???
I've reviewed a few of these over a few years, the question I keep having is about where does the gas go when you vacuum it? Is it in the pump and needs to be released? Do municipalities or shops collect it? I can rent a vacuum pump and have asked them the same thing and no one knows (I think because around here, no one rents them, they just pay someone). Also, you say it should take 30-50 minutes to draw it down? Others say let it go for a few hours? How do you know, till it's fully negative pressure, then let it sit (maybe that's what they meant)?
@@TutorialGenius I think it has to do with the red cap on your pump. Even though it says oil and the oil fill says air, they are pointing to the other caps. By removing the red cap, it will allow the fumes to exhaust.
Can you use this vacuum pump to extract freon from the system? What if in a year from now, I have to recharge my system again? Do I have to extract freon, contaminats, and water from the system using the vacuum pump before putting in freon again? I hope this makes sense. Thank you for the detailed video though.
1. No. (Take it to a shop to get it evacuated first, then begin this video) 2. If you need to recharge, but top it up with refrigerant. It's a closed system, so technically you shouldn't have to do this after a year anyway. 3. Yes You're welcome! :) Good luck!
Just excellent. You answered so many questions although I still have three. I am about to replace just the condenser on a 2011 Audi A4. 1) How much PAG oil should I add (if any). I was thinking about 1oz 2) The vehicle calls for 19.5oz of R134a but that has now been replaced by R12a. The can indicates 40% equivalent to R134a. I wish to confirm that I would only use 7.4 oz of R12a. 3) I noticed that your pressure gauge seems to have different scales for different refrigerant types. Is the desired pressure different for R12a v R134a Thanks
The service manual will say with regards to PAG oil. It depends on the the: make, model, and, if the new part already contains oil for: the part or the entire whole system. Many things to check with that. You need to check the manual AND the manufacturer of the part itself. I covered some of it in the video already, but not it too much detail.

Hey buddy thank you for that video you absolutely deserve a million dollars very detailed explain everything that makes sense to the commoner and you took your time. And you showed some scenarios. That we could try to troubleshoot. but at the enf of the day. You did a h*** of a job with the video. Thanks man.
I'm glad it was useful! Good luck with your project! (I'm assuming you have one to do soon!). :)
Some are mechanics but not everyone is a teacher, you are both!!! I love the fuse jumper cable piece, just in case!
Thank you
You are so welcome! Thanks for the kind comments! :)
Great tip jumping the compressor... thank you!
This video, for want of a better word, is priceless! Thank you to you sir!
Glad it was helpful! :)
Excellent vid and instruction. Thanks so much for taking the time to produce it.
My pleasure! I'm glad it was helpful!
Incredible video, mate! So much attention to detail. No idea why there aren't hoards of subscribers. You wouldn't happen to be from Zimbabwe, originally, yeah?
Thanks for the kind comments! Slowly but surely getting momentum here on TH-cam. It's a long and painstaking process, but maybe i'll get there in the end :)
Never been to Zimbabwe, but I have fancied visiting South Africa; I was going to go this year
Really a good tutorial.....very detailed and great step by step description. Thank you.
You're very welcome!
The most complete service explained
You're welcome! Thanks for watching! :)
@8:16 you left the cap on the vacuum pump exhaust while it was running. Isn't that bad? Also, my vacuum pump is very similar, and the manual says to take the cap off the oil inlet while it runs.
@10:25 Thank you for showing how to use the Adapter in all the details.
You're welcome!! :)
Great Video. Thanks for doing this. Helped me much...watched it twice. Done it before but been some years. Nice refresher. :)
Glad it helped! :) I hope you subscribe to my channel soon! :)
You're a natural ...one of the best on the topic
Thanks for the kind comments! :)
Well great step by step slow pace video for us 101 rookies lol...
So now I know how to charge it back !!!!! I will now look for your extraction video process, hopefully it's this clear also cause it's my first time doing this and im not to confident messing with pressure tanks and machines!!! 😅 Even though I definitely do mecanic work... thakx again
Glad it helped! 💥😊
I've watch 45 videos this weekend and this was my far the best, especially when using the little cans. The only difference was that you were the only one that instructed to open the high side during the vacuum cycle. But you way must be right because its working for everyone.
I dont know why you shouldn't ever open the high side but it was said over and over.
Only during the Vacuum,
High side Closed when
Charging freon on low pressure side.
The high pressure guage will still read the pressure, when valve is closed.
@@Gruindo you mean the high valve is open at the valve stem but closed on The gauge? I assume it would have to be to get pressure reading. I just ordered the kit and the high is only thing not clear to me.
Thanks for this and your attention to detail,I feel totally confident and am going to give this a go.
You can do it! 💪 Keep us updated!
Best video on this topic on all of TH-cam.
Glad it helped! :) Thanks for the kind words!
Wow, great video, thumbs up! One note, at 6:04 you said to use teflon tape on the pump threads, but actually that doesn't help at all, could even make it worse. Any time your threads are on brass piece attached to a hose, and they spin independent of the hose (same as a garden hose) then the washer or o-ring or rubber seal inside the hose does 100% of the sealing. Threads do zero% of the sealing because gas/air/water could just escape out the top where the threads attach to the hose and spin separate from it. The job of the threads is only to pull tight on the seal that is already there, and adding teflon just makes it harder for the threads to do their job.
It's to do with the fitting, not the material type. (I.e. brass)
IF you have a flare fitting, don't use it. Because the connector won't bottom out, and it CAN leak (Not always)
IF you don't, then use it.
@@TutorialGenius Sorry, I didn't mean it depends on the brass material, only that the brass piece you hold up and show us at about 6:05 spins INDEPENDENTLY of the hose. That means you do have a flare-type fitting or similar with an internal washer that does NOT want teflon tape. It is incorrect to use teflon tape on that exact fitting as you claim. It could only make the seal worse, not better.
@@Grrrnthumb Yes, if you have these types of connections, then I cover this in this video: th-cam.com/video/rN4FmSdzgxw/w-d-xo.html
very professional. clear vocals, great camera work thanks a lot my man..great job
Glad you enjoyed it! Thank you for the kind comments! :)
What if it goes to 20 and stays there instead of below 30 when u vacuum the pressure? Great video!!
Under normal conditions, meaning the system is properly sealed, and the pump and gauge set are working correctly, vacuum should pull to 30” of vacuum within the first minute and hold while the pump is running. If the system doesn’t pull down to 30” of vacuum at all while the pump is running, there’s a significant leak preventing it from doing so, or there’s a problem with the pump.
many thanks! First video I have seen that explained why I couldn't get the freon in the system (I didn't know that all the way screwed in AND out meant the can was closed!)
You're welcome! ☺
A very well explained process. Thank you. It worked perfectly. I also learned a bit about R12a versus R134a using 40% less refrigerant.
Glad it helped! :)
I Did A/ Few A/C In Cars,
I Never Used A Vacuum,
I Replaced Lines, Replaced
Compressors, Replaced
Condensers And Evaporator
Without Doing A Vacuums And
Worked Good Always.
Amén.
You did a few.
Educational... Thank you for taking the time to upload this video👍👍
My pleasure! :)
one thing to also keep in mind is to check your valves with a little spit hawk tuah. if you see bubbles take a small allen wrench and quickly press on the valve to reset the valve seat. probably one of the most overlooked leaks on ac systems
Yup, I believe I already covered this in the video, but I did neglect the hawk tuah part, thank you!
Excellent tutorial. I learned so much, that I actually think that I could do this. (Famous last words.)
You can do it!!! 😊💯💯
Loved this tutorial: well explained & you covered all the bases. Thank you!
Glad you enjoyed it!
This is great ! ! 😃👍 You’ve taken the mystery out of working on the ac.
I'm glad the video was useful! :) Thanks for watching!
You don't need to bypass the AC relay to jumpstart your compressor. The pressure switch on the high side line prevented the compressor to run because it has both minimum and maximum pressure required in order to run the compressor. Neither too low nor too high on pressure isn't gonna start the compressor. I only saw +/-50psi on your lowside, I say you need to get at least 70psi and then you don't need to bypass or force the compressor to start. Works well. Hope that helps!
Your excellent explanation I like attending school. Good job
Thank you! 😃
thank you for explaining why the PAG oil wont be sucked out when you vacuum, that had me confused af on other videos
You're welcome!
Great and very detailed video - you saved my day!
You're welcome!
It is clear tutorial... thank you . I have a question...
For Honda Accord 2008 - 2012... because the condenser come with the receiver drier assembled into one.
How much we need to add the PAG oil.... when we replace the condenser that come with the receiver drier .
If you do not know a specific amount, in general how much usually AC technician add it.. thank you.
Check the manual, it'll say the amounts of make-up oil of each component. So just add the two together
I have a doubt, please help me with that. I could see you did vacuum in both lines low and high but when you added the ac refrigerant you only opened the blue valve and my question is: the hight pressure line don't need to be filled with ac refrigerant? Or only the low pressure line has to be filled with ac refrigerant?
Appreciate you can helo to resolve my doubt.
Hi from Honduras....
I finally figured it out, some of the fittings had loosened up. I’ll leave this so that others might see it!!
Thanks again
A new subscriber, very good info. I have done all steps to pull a vacuum and when I open up the dial on the gauges manifold I get no sound change on the pump nor do I get any read like you do get to 30 , I get 0. Any thoughts would be appreciated!!!
Amazingly well done. Perfectly explained. Thank you thank you
Glad you enjoyed it! Thanks so much!
Definitely appreciate the detail of relays. Excellent altogether. 👍😎 Subbed
Thanks!🔥💯💯
@@TutorialGeniusDid my Caravan without incident yesterday. Last night my son brought over his CRV. Even jumping relay, I eventually” noticed the condenser fan fuse was out (clutch required this as well). Once replaced, we were done in 15-20 minutes. I’ve wrenched on cars 40 years, and wouldn’t have thought of forcing clutch. Many thanks again. 👍😎😎
@@joestocker660 That's great to hear!! I'm glad you got it done! Thanks for sharing with us all. Amazing!
Hello. This is a useful video, thanks. I just have a question: the vacuum pump sucks the oil too, or the oil remains inside the compressor and A/C system? Thank You. Have a great day.
It won't suck the oil... I believe I already mentioned this in the video though
Very informative and most helpful, thanks!!
Glad you enjoyed it!
An outstanding video. Thank you!
Glad you enjoyed it! :) Thanks for watching!
Thanks for the lesson. Well done. It's just what I was looking for.
You are welcome! :)
I love those Honda engines in that Vue.
Same here! 🔥🔥😁
I know I’m late, but is that one of those special Honda/gm Saturns? That looks an awful lot like a j series Honda v6. If so super cool, and also, very informative video!!!!!! I’m a commercial tech for reefer and diesel apu’s. Your video is awesome! I needed to re look up my knowledge on cars as I need to recharge mine and my wife’s. Your video was great.
Great it was helpful! :)
Yep, it's hard to miss that Honda engine!
Great video and explanation of the procedure.
Glad you enjoyed it!
Good morning family and thank you very much for the valuable information and for your time. 👍🏼👍🏼
great video very smooth and informative
Thanks for the video. You're a good teacher
I appreciate that! :)
Great video, about to do this tomorrow. Thank you much
Good luck! How did it go?
@@TutorialGenius Man, got it done exactly how you demonstrated and that thing spits out pieces of ice 😂😂😂 Thanks for what you do. God bless you 🙏🏼😎
You're welcome! I hope you saved a bunch of $$$!@@luiscarrasquillo9743
Great video. Very concise. Thanks
You're welcome! Glad it was helpful! :)
Does the oil poured into the compressor circulate throughout the system or do you need to put oil in the lines, dryer, condenser, evaporator separately?
Yes it will circulate! :)
I don’t add oil into the charge line as it will spray out when you purge your air but you can use a can of oil charge and add it to the low pressure side. I just drain and fill the compressor oil because I changed the compressor so I don’t add any oil.
No, you can't add a can of oil charge to the low pressure side this way (through the manifold gauge). I tried. Vacuum won't pull the oil up out of the can, and the hole between the yellow and blue lines is too small for the oil to get through in less than an hour.
@@philipgoetz8681 That's interesting because I just made a big boo boo. I opened the valve on the manifold gauge before i turned on my vacuum pump and the system sucked oil out of my vacuum pump. Now I have to find a way to remove all of the oil in my system as I have no idea where all the oil might have gone. I had just put new oil in my vacuum pump and after that happened it was no longer visible in the sight glass so I know it had to go in.
Great Video! When measuring the refrigerant weight for correct filling, how do you take account of the amount of refrigerant in the yellow pipe that was used to purge the pipe? Could a pipe load of refrigerant actually be quite a proportion of the specified amount, especially if it is in there as a liquid, rather than a gas, for pipe purging purposes? Or maybe the liquid refrigerant flows back into the canister under gravity before one opens the manifold to start filling, leaving only an insignificant amount of gas in the pipe? Or maybe you tare the canister once the pipe has been purged and then reconnect the canister?
Also, did you purge the yellow pipe in between canisters?
Thanks for any clarification given.
You don't need to worry about the pipe, I think you're over-thinking it. It's almost negligible.
The psi readings will tell you the pressures in your system, so go off those. Don't add x and y and hope its okay. If you add the 'correct' amount but it's slightly low on the readings, then add some more.
Yes, you should always do this: RE: "Also, did you purge the yellow pipe in between canisters?"
my gauge only went down to 25 psi on the mercury, is that normal? I have a 2008 Chrysler Town and Country and my system was emptied on the freon when I did the air bleed
Very informative and thank you. When i turned the pump on and opened the high and low Manifold Gauges, I never heard the sound of the pump changing as i opened them. Any idea why? Does that tell me that the system is not pressurized at all? AC has not worked for years and i just replaced ac compressor today.
I'm assuming the system was contaminated from the failed compressor? Did you flush the system before fitting the compressor? Otherwise, I guess if the pump holds negative pressure, I Wouldn't worry too much. If it doesn't, then there's a problem which may explain this
Man, thanks for the video I learned something appreciated.
Glad to hear it!
best video on how to do this Thank you
Glad you liked it! :) Thank you
Wouldn't it be better to fill in the lines up to certain point so when you go turn the carn on compressor can engage?
That's the idea, yep
For the vaccume pulling can I also use it to take out two types of refrigerant that’s in my ac
Your the third video that is great..i know fully understand the automobile AC system..im no longer afraid to work on my ac...my 99 chevy express, has zero freon..i shall repair my own..and save a bunch of money
Amazing! I'm glad it gave you the confidence! Thanks for watching :)
Thank you for the helpful video. I have replaced the entire AC system in my 1996 C1500. New compressor, accumulator, condenser, all new switches, every thing... I followed the steps here and even jump the compressor, however, I could not get the system to take the R134A. Can you advise? Thanks!
You either wasnt under negative vaccum and wasnt able to push any in. Or your low side hose didnt press the shrader down. If you had a vaccum and it stayed under vaccum you should have sucked the can down in 3 sec
Hello friend I have the exact issue with my new condenser did everything exactly as the video and jumped the clutch but it. would not take in the refrigerant. spent allday last weekend trying to get it to take it but it would not. Did you ever find a solution or what did you do to get the system to take the refrigerant??
Where should I start trouble shooting if after I vacuumed and filled the system with freon, go the test the system and I'm in a vacuum on the low side 50 on the high side with AC set to max, warm air blowing out, 75 degrees outside.
Just to confirm, low side is negative? sounds like the manifold gauges aren't tapped into the low side correctly? or there is a blockage of sorts
@@TutorialGenius they are in correctly so I have a blockage. My plan is to blow compressed air through the lines, replace the filter drier and the exp valve.
Very nice demo - thanks!
My pleasure! I hope it was useful!
How do you know how much amount of refrigerant you put in because most of the refrigerant the blue red and yellow hose must be holding..
Watch the video
Hello, I have a 2020 Toyota Corolla, I had to replace the condenser due to a leak, I have a question now when I add refrigerant, do I have to add oil to the compressor?
Does the new condenser include the oil? If not, then yes
Great video. No nonsense. 👍🏻
Thanks! 👍
IMO, this is the best and easiest-to-follow tutorial on the subject, and I have watched many. Although I would like a wee bit more vocal enthusiasm. 😂 Very thorough, knowledgeable, and understandable.
One thing I like to do for clarity is to photos of any manufacturer directions and add the appropriate links.
And, according to Socrates, Wisdom is limited to the awareness of your own ignorance. Meaning, it is inadvisable to self-refer as a "genius." If you think you are smart, you may be overestimating your faculties. Stay humble, friend.
I'm glad it was useful
If I charged $50 bucks for this content, I would accept that: RE: " I would like a wee bit more vocal enthusiasm". Sure!
But, you know, it's free, right? Take it or leave it haha! I'm a straight shooter, I'll be first in line to say your comment sounds a bit entitled! My kids are the same way. It annoys the hell out of me, but im old school! We are different generations of people, but I appreciate the the inclusion of nice comments a sight to behold!
Socrates once said: "Don't look a gift horse in the mouth". Or was that Plato? Who knows!
Don't you also need to add back some PAG (or similar) oil into the system after the vacuum is complete? I was under the impression that evacuating the system removed some of its critically important lubrication oil.
No, there is no need to add any PAG oil after the evac
You are so GOOD ! Good explaining .. Wow ! just wow
Thank you! 😊😊 I hope it was useful!!
fine video !!!! but i have a question ! how you know how much Pag oil you removed from system if you open high pressure side too when VACCUM the system ???
The answer is already in the video!
I've reviewed a few of these over a few years, the question I keep having is about where does the gas go when you vacuum it? Is it in the pump and needs to be released? Do municipalities or shops collect it? I can rent a vacuum pump and have asked them the same thing and no one knows (I think because around here, no one rents them, they just pay someone). Also, you say it should take 30-50 minutes to draw it down? Others say let it go for a few hours? How do you know, till it's fully negative pressure, then let it sit (maybe that's what they meant)?
You take it to the shop, have it recovered, then you begin this video.
The sitting is basically a leak test. A few hours is excessive
@@TutorialGenius I think it has to do with the red cap on your pump. Even though it says oil and the oil fill says air, they are pointing to the other caps. By removing the red cap, it will allow the fumes to exhaust.
Great video, thanks for sharing
Thanks for the visit!
Outstanding tutorial. Thank you.
Glad it was helpful!
That was a very well made informative video sir 👍🏼👍🏼👍🏼👍🏼👍🏼thank you.
You're welcome!
Can you use this vacuum pump to extract freon from the system? What if in a year from now, I have to recharge my system again? Do I have to extract freon, contaminats, and water from the system using the vacuum pump before putting in freon again? I hope this makes sense. Thank you for the detailed video though.
1. No. (Take it to a shop to get it evacuated first, then begin this video)
2. If you need to recharge, but top it up with refrigerant. It's a closed system, so technically you shouldn't have to do this after a year anyway.
3. Yes
You're welcome! :) Good luck!
@TutorialGenius Thank you very much :)
Just excellent. You answered so many questions although I still have three. I am about to replace just the condenser on a 2011 Audi A4.
1) How much PAG oil should I add (if any). I was thinking about 1oz
2) The vehicle calls for 19.5oz of R134a but that has now been replaced by R12a. The can indicates 40% equivalent to R134a. I wish to confirm that I would only use 7.4 oz of R12a.
3) I noticed that your pressure gauge seems to have different scales for different refrigerant types. Is the desired pressure different for R12a v R134a
Thanks
The service manual will say with regards to PAG oil. It depends on the the: make, model, and, if the new part already contains oil for: the part or the entire whole system. Many things to check with that. You need to check the manual AND the manufacturer of the part itself. I covered some of it in the video already, but not it too much detail.
Thanks very much for your speedy reply. I will hunt for the manual. Could you comment on the the other two questions. Much appreciated.
