Rear AC Block Off Kit, Fits: 2000-2014 Suburban, Yukon XL, Tahoe, Escalade: amzn.to/3PJN3HG Just so I'm clear. This is a winter beater. The rear lines are complete garbage underneath the vehicle. That is why I never cap them off or cover them up. If somebody wants to go back they would have to replace the rear lines and evaporator so there is no sense in doing anything to prevent dirt from getting in the old ones. Just thought I'd clear that up 👍
@@johnnysechrist6313 ASE is a joke when it comes to most things, it shows you can pass the test ONLY, doesn't demonstrate that you can actually understand the systems and do the work. Also ASE doesn't have any say in AC work, That would be the EPA, and the tests for both certificates for AC work (608 for fixed installs and 609 for mobile AC) are a joke as well. Why? They are open book tests!
I was a tech for 40 years. I really like watching your videos you are spot on with your diagnosis & repairs. I always told my technicians 90% of the repair is diagnosis the rest to clean & repair you're a great technician. Keep up the great work
Block off kits ??? Well, I've learned something new today !!! Will wonders never cease !!!!! You've been holding out on us Eric !!!!! This is a good thing to know !!!! I'll make a mental note of that for future use !!!!! Never a dull moment at SMA !!!!!!
A huge THANK YOU on behalf of my father! His '02 Yukon has been without A/C all summer due to severe corrosion of the rear A/C lines, and now he'll be able to get the system up and running and recharged! You rock, Eric! :D
Always enjoy watching AC work. Great job Eric! Rear AC lines in WNY can really give problems! Thanks for showing the rear-line block-off kit too. Have a great upcoming weekend everyone!
My lines on my suburban had a hole in them I found a set of rubber lines online through auto cooling solutions as well that go from front to back. Was easy to install and had lifetime warranty, can't remember. 5 years later still no issues.
Hard to believe how many worry warts in here about the rear lines that aren't to be used again. I have a hard time readin the comments when most are just nit pickers. You all come in here to see an experienced mechanic do great work, and an awesome gift of gab I must say, and yet so many question the trivial things that would drive most to drink. I guess maybe it is just a way to feel included. Ok, done bitchin, feel much better... TGIF
First let me say Eric is awesome so don't get thinking I am some hater! I have an 05 Tahoe rear air. I used a block off until I had time to go to the salvage yard get a used/ good line. My experience with block off was now the orifice tube would have a high pitch fluid sound as the compressor started. Wife found it annoying!
I have an 08 Tahoe. By the book, the repair is a body off job...But we found an aftermarket vendor that makes rubber lines that got us back up and going. Super happy we got it nice and cool in the back again!
I have an 05 Tahoe. Was able to go to the salvage yard pull a good used one off. Was able to get it in on my vehicle. I did have one of those nice compression fittings that I have seen Eric use To repair just in case I am to make it two pieces to get in.
Did the same to my 99 suburban 2 years ago, I bought the kit and let my mechanic install and charge it for me. Still plan to repair the rear AC one day when I have money to spare for it
Where I worked we did A/C on company cars. We were sent to school to get certified on A/C service. We were taught if you had a system that had a leak and was without a charge even for a short time to change the receiver/ dryer because it was most likely contaminated.
Pretty cool option for those that are looking to maximize the life out of there vehicles reasonably and still have some functionality like AC that works. Another great video Eric
Anotehr simple and awesome video. This is what I consider the practical reality of owning cars in the rust belt. it's not so much always repairing everything as much as making it livable for the next couple of years until the salt gets the job finished.
Every time I view your channel I learn tons. I'm retired so I'll probably never get to apply any of this knowledge. But thanks anyway for the many many hours of viewing. D Thurston
we have fixed the rear a/c lines on a 2005 & 2007 as both were leaking above the rear wheel. We used brake lines to fix the leaking liquid line. We did the 2005 4 or 5 years ago and it's still going strong! (Sold the 07 so no idea)
Good video. The rear AC in our 2005 Yukon and now our 2011 Yukon work very well, Arizona. But the kids are grown up now and we rarely have rear passengers. Good to have the rear AC blower fan going however, so R134a becomes a gas and doesn't flood compressor as a liquid.
So I went to the local shop and asked about pulling a vacuum and they had me walk 3 times around the shop pulling a ShopVac by the cord. I didn't notice any leaks, and I thought it was a strange, but for $100 I guess they're the experts! Happy Friday (and early Saturday) everyone!
Used this kit from Auto Cooling Solutions a couple times before on our prior Tahoes - getting ready to do the same on our latest one - Thanks for the tip on the Big Blu leak detector!
Pretty clean vehicle for a winter beater in your area! Haha. Good solution for that issue if you really don’t need that rear A/C. Here in Texas, we’d fix that A/C. Much needed here.
I used them for my 99 tahoe. Got the rear lines and evaporator. I was pretty proud of myself for actually accomplishing the job. Been working for a year now. The replacement lines are not rigid so installation is easier. Its nice to have rear air for the dogs.
I didn't put the kit on but I did put a new ac compressor with dry and hose along with a new expansion valve on myself then , took it to a machanic and had him pressurize it and add ac for me.
I didn't know these were a thing. My 2014 Tahoe the rear a/c line has some tiny holes in it and the line it's self is about $1,800 and not including any labor. Awesome I can get some a/c back in my Tahoe.
it appears the little nut and washer for the high pressure side block off goes on the end of the bolt where it passes through the fitting. They are probably not necessary (because that area is threaded as you mentioned) but it's nice they included them in the kit.
UA-cam. Gotta love it. You hover over the thumbnail for this video before playing it, and it scrolls subtitles of what is allegedly being said. "Welcome back to the self-made auction channel...". WTF? :-)
Lol. Your transitions to the comments are getting funnier. You kind of lagged a little like you weren't sure if you really wanted to say it that way but you did. I quietly chuckled.
Nice job! I'd be taking that gm dealer to court. There tech was just going to throw parts at the problem. The problem would have still been there. Again, Great Job.
I’m a auto technician I do this all the time that kit is like $7 Ac recharge with dye is like $120 so customers pay $127. Or The new lines with labor is like $600 with ac recharge $120. You choose $127 and nice cold ac or $720 and have cold ac.
Blast it with dry nitrogen and check for leaks. Only time that has ever let me down is with a compressor seal. And it naturally removes moisture so its a good test before the final vacuum.. And if ya want to go over the top you can get a hydrogen tracer in the bottle. But the hydrogen leak sensors are $$$$, However they really work.
honestly i don’t blame people for doing this i have a 2006 ford explore i just did the rear lines on and the amount of poo i had to remove to change them uhhhhh the only reason i did change them is that they were not that expensive and i had access to a lift but otherwise wow lots of work and i got lucky to have access as a friend of mine working at a shop that is crazy cool this never happens
Seems like the kit should have covers to cap off the rear lines as well to at least preserve what shape they are in now vs. let them get destroyed (unless they are all one piece to the rear). 36 is pretty cold for 134a systems, usually you are lucky to see 40. I've always liked the GM A/C designs vs. the others out there.
I’ll 2nd that motion should be caps to plug off the rear lines. Especially if the reason for using those fancy plugs is to be able to return the system to full capacity sometime in the future.
That's a nice option if you dont care about the rear air. Couple questions, why not replace the orrifice tube or check it for debris? Since the rotted out rear lines were connected to the system then there is good chance that there is debris trapped in the orrifice tube right? Second question, how do you know how much oil to add to the charge? Presumably there is some unknown amount of oil stuck in the rear lines/txv/evaporator. Lastly, to anyone who might try to DIY this, remember to only add the refrigerant charge called out for a GMT800 without rear air, otherwise you'll be adding WAY too much. Might be confusing if you try to search for r134a charge amount using "caddillac" or "escalade" since I think every single trim had rear air.
First of all, it was just a leak. Second, the oil charge would still be correct. Third, why would you keep opening lines and runnin up the bill? 4th, seems like it worked out very well. Quit your belly achin.
@@danlemke6407 👍Agree ! Eric did what was wanted by the owner ! Done every day ! Oil good , if the customer don’t care about his rear lines,,,,why should we ? Orfice tube,,,in high side line,,,not serviceable, have to buy new line ! F, it the guy wants cold air ! Not a heart transplant or MRI on his beater !
You have to watch which cap goes in the high and low. On the low side the Schrader valve sits up higher (not all of these trucks/SUVs), and if you put a high pressure side cap on the low, it'll touch the Schrader valve and create a slow leak. Since the replacement caps all touch the low side Schrader, we have to leave it uncapped.
If you manage to put the caps on backwards you are defying physics. The ports are different sizes. Large is high pressure. Small low pressure. Schrader vale should never be proud of the service port if it is installed correctly.
I have a 2012 Caravan where the rear A/C went FUBAR so I made the mistake of taking it to my Dodge dealer. They told me what the problem was so I said block it off. "We can't do that." So $2300 later I was cool again. The rear A/C on Caravans seems to be a common problem and is why the dealer keeps new units on the shelf.
Very popular vehicle , I’ve done many,,, reality check,,, “all vehicles with aluminum rear lines exposed to salt & now Brine , leak ! Regardless of the Hood Emblem ! +/- 5 yrs. ( made in China )
Great video I did not know you could close AC lines off like that. What happened to other AC lines? Did you just leave them hanging loose? I take it these two lines have nothing to do with the Transmission or colleant? Awesome video thumbs up. Stay well & safe everyone.
Thanks for the video Eric. Excellent views. Eric, just wondering, did you have formal training or are you self taught? My dad had an auto repair shop back in the 50s & 60s. He had no formal training but was a very good mechanic and everyone in the surrounding area brought their cars, trucks, and tractors to him to repair. I am 75 now and a lot of what I learned about repairing and maintaining vehicles back then has stuck with me. I was in high school back then and worked in my dad's shop until he sold it when I graduated. Cars are so complex now and you have to be an electrician as well as a mechanic to work on them. You amaze me with your electrical diagnostics and I learn from watching your videos, as well as Rainman Ray. Love both of you guys. 👍👍👍
I'm not Eric, but I know he worked for his father's truck shop (big semi's) and may have gotten his chops that way. Whether he got any formal training, don't know. He I think opened SMA in 2006.
Eric O has mentioned in a few videos that he had no training, not ASE certified, but did work on semi trucks for his dad's shop (now owned by one of his brothers).
I believe he grew up on the job training, but he has mentioned he attended some seminars and tech classes for CAN and other scope related topics. Other than that, he just has a great diag process system. Having some expensive scanners and scopes, along with expensive monthly subscriptions to access wire diagrams helps as well. I sure wish Eric was on UA-cam 30 years ago when I was starting out in the trade, I would have been more inspired by him back then, than I am now, when it’s just too late for me to start over.
@OneTwoThree FourFiveSix Except he was simply disconnecting the rear AC with no intent to get it running, the line to the back unit were rotted out. Mostly a winter beater now so the rear AC is not as crucial. Otherwise, he'd be doing all that.
@4:42 when I see those PED, Packard Electric Division, or Delphi connectors reminds me of my time at Delphi. I worked in the compound facility and they made millions of pounds of pellets in all of the colors you see a week. Things were good before the destruction / bankruptcy.

Just so I'm clear. This is a winter beater. The rear lines are complete garbage underneath the vehicle. That is why I never cap them off or cover them up.

In NC best not do any AC related jobs unless ASE certified in this field.

Nice find. I have worked on computers for over 40 yrs then hvac field. I have fixed many problems from corroded or loose wires.
I always look forward to a new SMA video!!! By far my favorite, along with project farm.
Eric thanks for helping my friend from Maine with her Honda Accord, she said you were awesome.
Anotehr simple and awesome video. This is what I consider the practical reality of owning cars in the rust belt. it's not so much always repairing everything as much as making it livable for the next couple of years until the salt gets the job finished.
Well Said! In salt areas , start moving cheap aluminum lines around,, hmmmmm looking for trouble ! Nip it @ the bud ! Good repair Eric !
I've done a little AC work recently, but it still seems like dark magic... But I always learn something from your shenanigans...
Getting my Friday fix of SMA... Have a great weekend Eric O.
You make everything look easy
Every time I view your channel I learn tons. I'm retired so I'll probably never get to apply any of this knowledge. But thanks anyway for the many many hours of viewing. D Thurston
I have made one by cutting the pipe and pinching it off and aluminum brazing it. It was a cheap fix for a vehicle that I wasn't keeping long.
They make caps and compression fitting kits. Just turn them on with open end wrenches.
we have fixed the rear a/c lines on a 2005 & 2007 as both were leaking above the rear wheel. We used brake lines to fix the leaking liquid line. We did the 2005 4 or 5 years ago and it's still going strong! (Sold the 07 so no idea)
Excellent video, thanks for presenting!!! The OCD in me says the kit maker should include plastic caps to plug the no longer used lines.
Wow never knew you could block off the back side of a AC system like that unreal unreal at a Cadillac has that kind of problems love the video
Lines made in China ! No salt ! LOL
Its not completely blocked off. The block happens when the lines split, so the freon has a path to still go through.
Good video. The rear AC in our 2005 Yukon and now our 2011 Yukon work very well, Arizona. But the kids are grown up now and we rarely have rear passengers. Good to have the rear AC blower fan going however, so R134a becomes a gas and doesn't flood compressor as a liquid.
GM uses an accumulator so you don't have that problem.

Very cool! Uncles Tahoe needs same. Thanks
That's funny. "We will check that by doing this" works every time.
Dude, you have been On Fire. Much appreciation for all the great content!!
Hey Eric O. Looks like you got a live one here.
Great Job 👏 Eric. Thank you for tip on what’s good on Amazon. There is a lot of junk on Amazon too
We all will be working for Amazon ! Sooner than you think ! Agree with the “junk” comment! LOL
The shop I worked at manufactured barbed fitting. On those trucks we'd solder on fittings and run reduced barrier hose back to the expansion valve
I used them for my 99 tahoe. Got the rear lines and evaporator. I was pretty proud of myself for actually accomplishing the job. Been working for a year now. The replacement lines are not rigid so installation is easier. Its nice to have rear air for the dogs.
The ground wiring was aussem. Thanks for sharing
South Main Auto.. Nice job, but you already knew that Eric. Thanks for sharing it..

👍 Just another day in Paradise !
Good ole Kendra & Natalie makin an apperance
Yhe good ol 34788 Robinair. Good machine. Great content Eric. Keep it going!
I didn't know these were a thing. My 2014 Tahoe the rear a/c line has some tiny holes in it and the line it's self is about $1,800 and not including any labor. Awesome I can get some a/c back in my Tahoe.
Hey there Eric. Happy Friday and thumbs UP!!
Cool love your work 😊I was gonna say just use some deedle nose vise grips 😅
Didn't know they sold Block off kits thanks for the info brother
2014 Chevy equinox a/c blows cool then blows hot and then blows cold
There were a couple of vales 6hat had had a visit from the valve nibbler
it appears the little nut and washer for the high pressure side block off goes on the end of the bolt where it passes through the fitting. They are probably not necessary (because that area is threaded as you mentioned) but it's nice they included them in the kit.

Best auto channel on the tube since Scotty shut up...!
You're the best! Another awesome video!
First thing to check! Clean your grounds.

Thank You Eric❤❤❤❤
Sweet. Didn’t know about this work around.
I’m a auto technician I do this all the time that kit is like $7
Ac recharge with dye is like $120 so customers pay $127.
Or The new lines with labor is like $600 with ac recharge $120.
You choose $127 and nice cold ac or $720 and have cold ac.
Blast it with dry nitrogen and check for leaks. Only time that has ever let me down is with a compressor seal. And it naturally removes moisture so its a good test before the final vacuum.. And if ya want to go over the top you can get a hydrogen tracer in the bottle. But the hydrogen leak sensors are $$$$, However they really work.
I had a 1982 Suburban with the rear A/C...it leaked...I decided to block it off.
A couple of small Vise-Grips and what do you know...no more leak!
I thought of body ground (said it to myself) and here we go fixed correctly.
Just by the way things were and were not operating correctly.
Nice kit! Chevy thunder!
I would do the same had some on Mercedes using that type of braided strap they hate the salt eats away and fitted a solid type no more problems 👍
Great fix and quick.
I like the AC stuff thank you.
honestly i don’t blame people for doing this i have a 2006 ford explore i just did the rear lines on and the amount of poo i had to remove to change them uhhhhh the only reason i did change them is that they were not that expensive and i had access to a lift but otherwise wow lots of work and i got lucky to have access as a friend of mine working at a shop that is crazy cool this never happens
Thanks for all of the vids Eric
Spent most of my life in manufacturing. Unfortunately, some people have no pride in producing a good product.
Ya, I wish I had an R134A machine. Don't know where you could rent one, never heard of that, but it would be a big help.
Nice work Mr. O!
Maybe I'm wrong, but I think he means rent the vacuum pump. Vacuum down the system and the charge with 410a cans.
I probably would've put a li'l spot of refrigerant oil on the new seals, otherwise it's all good.
Seems like the kit should have covers to cap off the rear lines as well to at least preserve what shape they are in now vs. let them get destroyed (unless they are all one piece to the rear).
36 is pretty cold for 134a systems, usually you are lucky to see 40. I've always liked the GM A/C designs vs. the others out there.
I was wondering this also.
I’ll 2nd that motion should be caps to plug off the rear lines. Especially if the reason for using those fancy plugs is to be able to return the system to full capacity sometime in the future.
For that price, they should have provided the block for the now open rear lines, no question in my mind. .
It is only running the front evaporators, rear ones leaked and are disconnected. Super cold.
Thought so too but I think he said the rear lines were leaking. If so, probably need to be replaced anyway hence capping front only.
Another Cool video Eric 😎🍦🍦, top job there 👍
@6:00 Sure is a good optical illusion, it looks like both service ports are on the same line.
Both ports may be on the same line. One before the restrictor and one after. High pressure ahead of the restrictor, suction pressure beyond.
That's a nice option if you dont care about the rear air. Couple questions, why not replace the orrifice tube or check it for debris? Since the rotted out rear lines were connected to the system then there is good chance that there is debris trapped in the orrifice tube right?

Hot🥵we need that a/c bro🥶
just got one from them to block off a Frieghtliner sleeper
As long as the a/c was discharged wouldn’t it have been cheap preventive maintenance to replace the Schraeder valves?
I wouldn't. Schrader valves are long lasting in a sealed system (caps on) . One of those mechanical things you don't fix if it ain't broken.
Eric thank you!

I sure wish Eric was on UA-cam 30 years ago when I was starting out in the trade, I would have been more inspired by him back then, than I am now, when it’s just too late for me to start over.
@OneTwoThree FourFiveSix Except he was simply disconnecting the rear AC with no intent to get it running, the line to the back unit were rotted out. Mostly a winter beater now so the rear AC is not as crucial. Otherwise, he'd be doing all that.

@4:42 when I see those PED, Packard Electric Division, or Delphi connectors reminds me of my time at Delphi. I worked in the compound facility and they made millions of pounds of pellets in all of the colors you see a week. Things were good before the destruction / bankruptcy.
Nice kit and job , thanks
