Unlike some videos, your explanations are detailed which is what most people look for.
Great video. Have this same machine at work. It does a great job.
Thanks for your time and effort to make these Vids !!! Cheers !!!!!
big fan from Ireland I'm glad found someone as passionate about the job as me . one question did you always want to be a tech cus I definitely did
keep wrenchin bud
What a great tool! How far we've come from the days of slamming a can of R12 in to a system and hoping for the best.
haven't watched your video but I know I'm always satisfied knowing a fellow technician is teaching future technicians __Eddy
Eddy - might want to take a look at his videos.. there are some really cool gems in there. Really Great Videos for sure.
Thanks again Mak! Wow that is some machine! Humans are amazing!
Great informational video. Can you or someone you know do a video on troubleshooting the LCD screen? Thanks for your time.
I’ve got a question for you if I could. I just changed out a condenser in a 2010 Escape that had front end damage. While the garage was trying to refill the system it pulls a good vacuum but when it tries to fill it with the 1.56 lbs of Freon, it only gets to .6 lbs before it gives a failure code. Have you ever ran into this problem?
thank you so much for the information been looking for this exact video for a while
On a 1995 ford ranger 4.0 the a/c system calls for 1.9 LBS. What would cause a failure to compete the charge? We are using a KoolKare plus machine . This machine has the option to charge on the high or low side we have been trying to charge on the high side is this the proper method or should I charge though the low side. Thank,s for the vidos and keep them comming.
Does the machine come with specs on refrigerant and oil capacities for different vehicles?
Excellent video.
Had a question, I have an older robinair very similar to this, and it does not tell me to equalize hoses after charging. I end up with pressure still on the gauges after charging the system and disconnecting the hoses. I normally select recover after disconnecting hoses and get about .25lbs out of just the hoses. Is this .25 not making it into the vehicles system? My manual says nothing about equalizing like yours does.. thanks Dan
Hi, how and where did you inject the oil into the system? THANK YOU FRIEND
If my ford 99 f150 gets low on from I put a can or two in with gages and gets me thru fine. Must be a very small leak. Do you recommend from with the stop leak in it? Never tried that yet
Thank a lot for the class !!
Gr8888 Video and with clear details!!! I subscribed!!!
thanks brian. best repair channel on youtube
Thank you for the great video, very informative. But I do have a question. When you charged the system with R134 you did not start your vehicle or turned your AC on. What"s recommended? Thank you in advance.
when using these types of machines. the machine does all the work. it charges to the vehicle specs. .. disconnect the machine and Then turn on the car and the a/c… its not like the freon can and hose.. where you turn the a/c on and then add the can(s)
Thanks man. I'm in TH-cam heaven. I just watched a Schrodingers Box video, spotted yours on a good subject, and I'll be watching ETCG after this. :)
HAHA. I wish this video came out a month and a half earlier. I would have looked smarter in front of the boss, but that's okay. Your thoroughness always teaches me something.
Screw Scrotumingers Box. He's an egotistical jerk wad that doesn't know half of what some humble youtubers do. He's such an ass in his videos. It's pretty unbelievable.
Banshee365 You know it's an act right? He's actually nervous to share on camera and that's how he covers it.
TH-cam is completely outside his comfort zone.
You like ETCG though? He's pretty calm for his videos.
Banshee365 I agree. I used to watch his videos. But he is too negative about others that I just couldn't continue to watch him any longer. He is a smart guy, which means he doesn't need to put others down.
So if you add oil to the compressor before vacuum, does that oil stay in the system during vacuum?
What should my pressures be on a 2011 F-250 high and low side?
Great Video. I had a problem with wife's 2007 Camry. Thought it was a a possible blend door issue but turned out to be something different. Dealer wanted $2800 to fix the problem. $2500 for a new Control Panel and $300 for diagnostics. I said no thanks and drove home. Watched a few videos and talked to a few friends. Made a trip to the local auto store bought a can of A/C charge for about $50 and all is well in the land. No problems. It was just low on charge. We have no proof but suspect the local repair shop that we recently went to had let the charge out because I made them pay for a new radiator after breaking mine while replacing my alternator. They were also upset that I made them wipe off all the greasy hand / glove / paw prints off the hood and front of the car when they were done. Don't you love just love it when someone uses an oil filled rag to wipe up oil. I mean really, how much oil can a oil filled rag hold before it just smears it around? OK yer cars done!! That'll be $157.99 Please!! We even wiped'er down a bit!!
Hawaiian F150 can't find good shops anymore I tell you. South Florida is garage hell
Yea i worked cars too for brief career (Toyotas)1995-1997
Many times i need repair shop equipment to DIY on my cars . Many tech are not talented or need quick money and will cut corners
Thanks for the video
I saw the option to recharge from both sides( Hight and Low) is that correct or something will be bad?
Very well explained. Thanks.
,I have problem with my grand marquis 2005 ,the compressor going off to fast and run again when i start driving ,gas is OK compressor is new ??
recovery happens with the engine off? is there going to be any oil or dye trapped on any components that don't flow through with the system off?
So when you drain the oil..does it take oil out from the compressor too ?
I have a 2008 toyota corolla ce and a had leak on the low side port I change both valve low side port and high side port valve I did a vacuum for 20 minutes and I put a little oil in the system is don't know what I did wrong it's not cooling like before what the issue do the low side gauge reads 30
Can it suck all the old PAG oil, even without the refrigerant in the system? (et's say lif you installed a new drier, compressor...ect. This way you can put in the correct amt of oil system requires, if you can remove all the oil from the system even from the new compressor which some comes with oil in it. That would be great if it can do that. )
Hi When adding the Freon with the machine has to be with the vehicle turn off ?
How should I dispose of the a/c oil ? Same as regular oil
nice job
thanks for the videos I bought the same setup last year, I have the robin-air die injector gun and it is tiny. Where did you get yours sir?
This is the one I use- amzn.to/2xi3buZ
Do u always need a vaccum? What if u know theres enough in there for the compressor to turn on but not enough for it to be cold
Hello!. I have a 2007 Eddie Bauer Explorer 4.6 V8. The AC never have been recharged and I realized that it is not cooling as several years ago. Can you help me to identify the Low and High ports used for recharge the air conditioning system with the appropriated gas and the maximum capacity of the Gas? Thanks a lot in advance!
Thanks for the great video. My mechanic says they will inject dye to make evident any leaks. Do you do that? Thanks.
Of course
And do you have to close the valves before you charge ?
HELLO AMIGO EXCELENTE VIDEO SALUDOS DESDE COLOMBIA LLEVO BASTANTE TIEMPO VIENDO TUS VÍDEOS Y SUSCRITO A TU CANAL YO TRABAJO REPARANDO EL SISTEMA A/C HERMANO POR FAVOR HACELE TRADUCION A TUS VIDEOS SON DE GRAN IMPORTANCIA Y LA VERDAD NO LE COMPRENDO BIEN EL INGLES GRACIAS POR COMPARTIR TU CONOCIMIENTO
When did you add the refrigerant?
How did you know how much oil to put inside also should the high side be 200?
Can this machine use the old freon to recharge??
Hi. What’s your opinion and advice on mahle ac recovery machines. Why they come for hybrids and regular for separate. Does your robinair ac machine do the service for hybrids vehicles as well? Thank you boos.
Hybrids are no different, the new ones just require a special oil you inject separately for the electric compressors.
If the system is empty because of an accident by a friend who accidentally hit one of the lines to the compressor and all refrigerant leaked out with psssschh it was a very warm/hot gas that was coming out.
Ive replaced that small little line of like 30cm. What about oil then? How much to add? Did the oil escape out when the gas did?
or can the ac machine still recover if any oil are still left in the system and then add the new correct amount?
sorry for my english :)
What about the air that gets introduced when you pulled the low side hose off to inject the dye & oil? I know it's not much, but there has to be some in the hose if you break the connection.
Do you not have a separate hose connection for adding oil? Might be time for an upgrade?
I always put the oil in the compressor, condenser, and accumulator before sealing it up and running vacuum.
Do you need to turn and run the engine when you doing this process?
Thank you for the video, Shouldn't you purge the air in the hoses first if you just want to check the pressure level otherwise air will get into the system? please clarify.
Thanks
With this system there should never be air in the lines at all. The lines should only contain refrigerant or be in a vacuum.
Thank you so much for your reply. I appreciate if you could guide me to the right way to prepare a new manifold gauge by purging it to check the system pressure then connect the yellow hose to a refrigerant can. Not sure how to purse the 3 hoses as well as the manifold. I have not find anyone explain this. Thank you
one more question. when disconnecting the hoses after you are done does that mean air can get again to the hoses from the valve that you connect to the high and low pressure ports?
When you change a compressor do you drain the oil from the new compressor, measure it and put in the amount required in the system specifications?
Yes
Great video as always, thanks for taking the time to teach us so much!

Frustrating
I want to to know if all oil comes out
At 5:44 i cant figure out what word is said referring to oil evacuated too.
Can someone tell me what hw said?
I have a 03 explorer limited when I have ac on the compressor turns on an off quickly an passenger side vent blows warm /cool air driver side blows hot an now lost my rear heat an ac any advice please
Classic low charge indication get the system evac and recharged and add some dye to see where the leak is.
One of the steps when replacing a compressor is to flush the system, but often people gloss over that step. I've seen some use compressed air, which seems like a strange thing to do since high pressure air will always include water that will condense everywhere. Is it common practice in the automotive industry to use compressed air, or do many shops use nitrogen? Is it common practice to use a volatile flush solvent?
I have a #SNAPON at work. I have never had to use it,I figured I would get ahead of the curve. Just in case I have to operate it..
That Milwaukee toolbox is badass
my machine shows "oil drain error 2" when i recover or vacuum the system, what should i do?
How long does this process take
Thanks! Are you charging with the engine on or off?
Also do you ever verify what pressures are in case you ever find yourself helping someone who only has gauges?
I was surprized that you only put the amount of oil in that came out as opposed to putting closer to the system spec back in.
Many times when a bad compressor is taken off it will be completely dry with zero oil in it. When it came new it had 4 oz's.
I was wondering how the amount of freon is determined by the designer. Do the teach that info? Thanks! love the exciting music up front.
Should be on
No done with engine off. The machine has setting to fill as per weight required for your system.
@@aki31286 Just say you had an all new system, line , ac compressor, condensor, evaporator, everything. How much oil would you add above and beyond the compressors oil requirements?
Someone blew my mind the other day saying if you don't add oil to coat the lines and components the lines and components will rob all the compressors oil causing premature ac compressor failure.
Where did you buy this machine?
Wonder how you fix an a/c system that had been Open, then closed and charged with refrigerant and oil, and maybe too much of one or both?
Same way. Pull the current charge out, vac it down and recharge.
Ah so you had to inject the oil? I thought this thing did the oil too or maybe it just separates oil from freon?
Does a recovery unit like the Robinair RG3 have an oil recovery tank? I am thinking of getting one for personal use.
How much does a Recover and Recharging A/C typically run to or at least ball park average figure? Thanks...
Looks to be about 3000 bucks presently. I'm a tool junkie prone to buying tools even for one shot personal use, but this is too rich for me, lol. Half that price I might might start making up some imaginary reasons to justify buying one.
I just bought the same machine. So far I like it but I am more familiar with an automatic machine. Can the Gauges be used on the machine after recharging as long as the panel valves are closed? I like to monitor the pressures to assure there are no potential blockages or other issues. Thanks ! I enjoy your videos!
Yes they can I use them all the time. I use mine a lot now and I still love how well it just works.
Hi....anybony can buy this machine or only licenced people?....one not question, the frion u colect it from a car, can re-use or not....I ask cuz I fill my car with frion but the expantion valve it's block and I want to replace but don't want to toss the frion I already put on it.
@@raulayala5891
For nearly $3000, it's probably cheaper to bring it in or use new refrigerant than buy one. Not practical to get for a one time DIY job, as cool as it would be too have one.
@@raulayala5891 Yea anyone can buy one but if you want to be offical get the mobile AC cert. Its only 15 bucks or so and u can then buy R-12 and now u need it to buy 30lb cylinders of R-134a thanks to Obama and other world leaders at the time who signed that into law. I have the same machine. I used it on my fleet of cars many times , paid for itself already in what repairs would of cost
2013 A/C question F150
ecoboost
when not in recirculate mode using just vent I still get some heat into the cab,... so I have to use max A/C to get any decent cooling,... my question is can I pinch/clamp one of the heater hoses to get around this issue? which one?
the dealer gives the typical everything is normal answer but there should not be heat coming in when I try to use the cool vent on a cool day,.... plus I dont get much a/c unless I am on max but i want fresh air a/c usually at night
what do you think about that story?
robert in niagara falls,.....dealers here are very bad!!
Sounds like the blend door isn't closing all the way. It directs the path of the air coming through the HVAC box. Take it to a different place or dealer and have them check it. It may be normal in that the air intake for the heater system could be getting heat from the engine compartment.
Ford used inline heater valves for a lot of years. I would get it checked first though.
when it is cool outside and I want that fresh cool air inside I use vent but I get warm air, the dealer says its working normal but they always say that so if I dont trade it in on a honda I may put in a valve
Do I need to add oil when charging the system after pulling the vacuum?
yes
I’ve always seen these machines in the shops. Never got to use one.
Brian, You are a maniac! :) One question, where do you get large cans of refrigerant?
I got mine on Amazon for just over $100 I just cant beat that price even with my local suppliers. I only use Dupont amzn.to/1TXCMJB
Question. If i take my car to a shop and asked them to recharge my system, do they add PAG oil back in??? I think i need PAG oil in my system as my low pressure line snapped, lost all refrigerant and i replaced it. I'm in NYC so i dont need AC right now, but just wondering if i have to put in PAG or will the shop put it in with the recharge?
Yes they should add PAG because it gets removed during the recovery process.
@@FordTechMakuloco My new compressor, UAC said it comes with the pag oil preinstalled.... I'm thinking i just need to pressurize the system and fill it will refrigerant.... not sure, i may get one of those kits and save me some money.
Great video and explaining. Are you knowledgeable with old Harrison A6 GM compressors.
Thank you for this Great video ..
but i have question !
most car dealer has common method to fill the AC when engine On and with pressure Gage , what is the difference between them . !?
The different is to know how good is the ac compressor, that's for the high pressure line have to be connected ,so in that case if the compressor is good or not u will know by the pressure
Got my 609 cert. a few years ago - great investment come summer time...
I searched your channel and I have a non-A/C question :
On the Focus Mk1 (2004 SVT) is it possible to remove and replace the _front sway bar bushings_ without dropping the subframe? The end links are good but all the bushings are original double digit years old and it's time for a set of polyurethane bushings. I will also have the lower control arms off during the process but don't have a lift. ANY tips & tricks will be very appreciated.
Im in the same thoughts. Ive read that its possible to do without dropping the subframe but its a very tight job I've read and seen on youtube. People made it though.
how do you know that the bushings are bad?
@@orfeous UPDATE - it's not too difficult if you have a LOT of extensions with a few universals then work it from the top. Factory bushings are _always bad_ compared to urethane bushings.
@@dieselscience I'll guess the bolts will not be easy to remove though after all years. :)
@@orfeous They're heavy to start with but I used breaker bar.
If the compressor seized up and likely sent metal into the system, will that contaminate the ac recovery machine when recovering the refrigerant?
no
Hi, I love your videos.. Great Work. I have a 2003 Tribute with 165k miles. I changed the compressor because of a bad pulley bearing. I used a re-man'd 4 Seasons compressor. It failed after about 8 months(leaked from the compressor). They replaced it, but the replacement had a bent pulley shaft which caused a leak. They again replaced it, but the third replacement was noisey from the beginning... Then it too leaked out the coolant. I gave up and went to a local repair shop. He used a NAPA compressor which lasted 3 weeks, and it too was leaking from compressor. The local shop re-charged the system about 3 weeks ago... So I'm waiting to see how this compressor works. Any ideas?? Each time the compressor was changed, I changed the receiver/dryer and orifice tube. The shop claimed to have flushed the system too. Thanks!!
Just use a Ford reman and be done with it or use Spectra Premium.
+FordTechMakuloco Thanks for the advice!
sorry sir but i will like to ask you a question. i have a 2014 toyota prius and the ac/c was leaking due to hitting a dear, fixed the leaking but i dont know what amount of oil nd 11 to put as everything came out out from the a/c when i change the part. do you know the amount of nd11 oil to put on the a/c. many thanks jose.
Hi! How do I recalculate/recompensate for the lost oil that goes with the refrigerant on recovery or loss? Is there any mathematical formula to determine how much oil is left on the system parts after the recovery?
Does that machine flush the system also?
How fill air for check leakage in ac lines
the system is recharged with the car off ?
Thanks for details will try to recover tomorrow refrigerant to take off ac off the car
Hello,you did not show us how you injected the oil.
arent u suppose to turn ac on to max once you charge the ac system up?
+jini08taeki no
In your opinion, is it possible to damage the compressor by adding oil through the low side, since it will have to travel as a liquid through the compressor? Can the compressor get hydrostatically locked and damaged?
Um no.
Very interesting. After a recovery and a passing leak test, I was taught to "Never " add pay oil through low side because the oil would have to be compressed as a liquid and that it could damage the compressor. Good video though.
The oil injection gun adapter is only made for the low side port, if it was potentially a concern then they wouldn't sell it with a low side coupler.
If you don't mind my asking, what does this machine cost? We need a new one, but I'm not sure what to get.
This is the one featured in this video- amzn.to/266nw2L
It has all the features you need and non of the one you don't like the next model up. I have always use Robinair over the years with great results.
FordTechMakuloco Thank you!
Does it recover from high and low side simultaneously?
+Blade yes
FordTechMakuloco Would I have to flush my A/C as well? Or does the Evac take care of this step?
When you do recovery thats it sucks all the oil too?
No only an ounce or two
Hello boss, I'm vacuuming 2011 but I can't reach -30 hg psi just -17 is that normal
No
@@FordTechMakuloco what could be wrong?
@@tizocchuck5944 The only 2 things I can think of is that either you have a small leak or your vacuum pump is worn. Check your set-up first with out connecting to your car's A/C system to eliminate your set-up is not leaking or your vacuum pump is worn out.
how much should you charge per vehicle when doing this service ?
Each car is different there should be a sticker on the hood or frame
250
It depends on the vehicle. Follow manufacturers specifications. There may be a sticker near the compressor.
@@lashawn2028that’s what I got charged 2016 LEXUS IS for 2hrs
how much does this machine or a similar one cost? and are they reliable or do they break down... also,If i wanted to open up an small ac repair shop in my area do i need a special license, I took an appliance repair coarse where if you work with refrigerant you need to take a special certification test ...i am located in sw florida... great video...thanks
Robinair is the industry standard and I feel the best machines. This is the one I feature in this video and is really all you need- amzn.to/2um9sCm
I have an appointment this Friday for this at Ford. They start price at 179. Is this a fair price? Seems kind of high to me
08 Crown Vic.
Seems pretty high to me ,I bought a Grand Marquis from a ford dealer in Feb . In may I realized the air conditioning blew hot air so I called him up. He said he would take care of it .Him taking care of it cost me $144. 00 but at least it works now !!
I don't know much about this kind of Repair.. but what I do know is that Everything now days is Smaller and cost 3 or 4 times
+John Rhodes It does seem high but it depends what the labor rate is in your part of the country we used to get paid 1.2hrs for an evac and recharge. So if the labor rate is $130 an hour you can see how this can add up. If you are just getting an evac and recharge goto a regular independent shop much cheaper for a basic service.
+FordTechMakuloco I bought the car about 2 years ago and the a/c was dead. I put a big can in and it has held pressure. I live in Rhode Island and bought the car from a guy in Virginia on eBay who told me it was from a small Colorado police dept. I must say for a used CVPI with 69k on speedo it runs excellent. I am just thinking it would be good to have it hooked up to the machine and have proper levels of pag and freon. I think the dealer is 100 more than the independent shop. I don't know if it's going to need any new parts or not and I like OEM just not the prices. Lol
Here in sweden it costs around 150-230 euro
Why no one of specialist youtuber talk clearly about Oil process ...
The machine recover and drain the hole oil system including compressor oil...or just recover oil from condensor, evaporator, dryer and hoses only?
How to know there is excess or missing oil?
How to proceed with ideal oil charge with machine..or we should do it manually?
I searched a lot on TH-cam, websites and forums..But i did not find anyone talking in a clear and practical way about this topic.
For example:
Oil chart :110 ml (hole system manufacturer's instructions)
sir well don
Does it suck most or all the oil out?
Usually 1-2 ounces comes out with the refrigerant and drained in the bottle below to be measured.
I over charged my 2016 Altima, sobI took it to a local ac person and they hooked it up to a machine like this and it’s still blowing hot
does pulling a vacuum take the oil out of the compressor?
Only an ounce or so comes out with the refrigerant you just need to check the oil recovery bottle to see how much.
ok, thanks!
@@FordTechMakuloco Hi what if my AC system already low on oil does the service man know...I mean what if the oil catch can is already low how would the mechanic know that the system needs more AC oil?
Can you explain the last step equalizing the system etc.... in more detail please.
Hallelujah!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
It keeps asking me for a serial number and I have no clue what to put
Can I reuse the refrigerant by this machine instead of recharging fresh
Can I reuse the existing refrigerant by this machine instead of recharging fresh from new container. Because it will save money and stop environmental pollution as well.
The machine recycles the old refrigerant and reuses it.
@@FordTechMakuloco, that means I can suck the existing refrigerant and after that I can also dismantle the whole A/C system to get repared, and recharge the old refrigerant again after reinstalled?
Why the machine recover and drain 4 ounces of oil but you inject only 1 or 2 ounces..!?
Any explanation.!
