In this video I bring you along as I block off the leaking rear A/C lines on a 2005 Cadillac Escalade. It is a kit I bought off Amazon and it fit and functioned perfectly.
-Enjoy!

    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.

  2. Avataaar/Circle Created with python_avatars ROBERT R Penny says:

    EO what did you do with the rear line connections?

  3. Avataaar/Circle Created with python_avatars Steve Perrett says:

  4. Avataaar/Circle Created with python_avatars Maxime Jette says:

    hey Eric do you fill a report every time you use the AC machine on a car? because we dont but got told by a friend that we do have to fill up a report.

  5. Avataaar/Circle Created with python_avatars Thomas Gilbert says:

    Should you have taped off the unused lines to keep debris out?

  6. Avataaar/Circle Created with python_avatars Jon Clark says:

    The rear A/C lines on my Sienna were leaking, but rather than block them off, I repaired them with a repair kit from Dorman (yeah, I know: eww, Dorman. They're actually really nice and work great). Cost about $50 per kit, easy to install, and the rear A/C is still functional.

  7. Avataaar/Circle Created with python_avatars Mark Malikowski says:

    Excellent video as always Eric.

  8. Avataaar/Circle Created with python_avatars Randy Cremeans says:

    I like how everyone says they was a tech for 40 years everyone wish they were as good as Eric O he is the best you would not be watching if you were that good

  9. Avataaar/Circle Created with python_avatars HE4RT says:

    That's a sweet kit right there now, does that company offer a block off for them lines that are disconnected so debris doesn't just pour in them? Ya know like save what components that would still be salvageable in the rear ac. Unless all from the front to rear is all junk then who cares. Just curious Mr O

  10. Avataaar/Circle Created with python_avatars rizzodtheRCvlogger says:

    why does he need working A/C in his winter beater? our winter beater hasn't had A/C in years.

  12. Avataaar/Circle Created with python_avatars Brian Delpino says:

    In my suburban I ended up buying all the parts from a pickup and swapped it over lol

  13. Avataaar/Circle Created with python_avatars Thomas Tommy says:

    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.

  14. Avataaar/Circle Created with python_avatars Dan Hoagland says:

    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.

  23. Avataaar/Circle Created with python_avatars Phil French says:

    YouTube. 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? ๐Ÿ™‚

  35. Avataaar/Circle Created with python_avatars Mike Hudson says:

    Shame the hard lines cost so much and rubber hose replacement kit runs $350 to lose the rear AC use. Guess the kids can sweat.

  36. Avataaar/Circle Created with python_avatars Stephen F. Selden says:

    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.

  37. Avataaar/Circle Created with python_avatars home serve says:

  38. Avataaar/Circle Created with python_avatars brian willoughby says:

    Shade tree mechanic can maybe do this ac job.

  39. Avataaar/Circle Created with python_avatars Daniel Weston says:

    Iโ€™m a little confused. Not super mechanically inclined. What is it exactly this kit does? Will the AC not work anymore?

    I always look forward to a new SMA video!!! By far my favorite, along with project farm.

  48. Avataaar/Circle Created with python_avatars Dan Lemke says:

    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

  49. Avataaar/Circle Created with python_avatars GlassVial says:

    Surprised this is a 2005 and a winter beater and isn't in the crusher already. I'm guessing it's days are already numbered.

  50. Avataaar/Circle Created with python_avatars Joe Butchko says:

    I noticed the stud snd bolt provided were rather long- was there enough to maybe include the old line, thus the new piece acting as a clog in the line. All lines closed off and no open lines to pick up contamination.

  51. Avataaar/Circle Created with python_avatars Mellow Guy says:

    I probably would've put a li'l spot of refrigerant oil on the new seals, otherwise it's all good.

  52. Avataaar/Circle Created with python_avatars Thomas Fraley says:

    just got one from them to block off a Frieghtliner sleeper

  53. Avataaar/Circle Created with python_avatars Robert Geear says:

    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.

  54. Avataaar/Circle Created with python_avatars Renegade's Garage says:

    South Main Auto.. Nice job, but you already knew that Eric. Thanks for sharing it..

  55. Avataaar/Circle Created with python_avatars Ron Johnson says:

    Never trusted an electronic leak detector. If you read the manual that comes with a Matco leak detector it has a list of chemicals that might trigger it and basically if you are in the vicinity of a car it might be triggered. Seriously, it is a list of like 50 things that can all be found in a car.

  56. Avataaar/Circle Created with python_avatars Philly Dee says:

    Hot๐Ÿฅตwe need that a/c bro๐Ÿฅถ

  57. Avataaar/Circle Created with python_avatars Craig Brown says:

    That's funny. "We will check that by doing this" works every time.

  58. Avataaar/Circle Created with python_avatars shumanchu1 says:

    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.

  59. Avataaar/Circle Created with python_avatars Matt Stewart says:

    Nice

  60. Avataaar/Circle Created with python_avatars Ron says:

    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.

  61. Avataaar/Circle Created with python_avatars Keith Bowers says:

    Why not just fix the rear ac ? I'm not being ugly I'm just curious

  62. Avataaar/Circle Created with python_avatars David Ellenbaum says:

    surprised it didnt rust away

  63. Avataaar/Circle Created with python_avatars old biker says:

    too bad the studs weren't longer could of piggy backed the lines to the rear .

  70. Avataaar/Circle Created with python_avatars Guy Cocoa says:

    As long as the a/c was discharged wouldnโ€™t it have been cheap preventive maintenance to replace the Schraeder valves?

  71. Avataaar/Circle Created with python_avatars Michael Johnson says:

    Eric thanks for helping my friend from Maine with her Honda Accord, she said you were awesome.

  72. Avataaar/Circle Created with python_avatars TargaWheels says:

    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.

  73. Avataaar/Circle Created with python_avatars daveyio87 says:

    I like those, we usually use the press on block off caps from FMS. I've used the dorman compression fittings and they do work good but the line needs to be clean or they leak. usually when i block them off i use the caps on the one side and then i crush the other side and roll it up. we both know that once its blocked off that owner isn't going back.

    Mr.O Cool video.

  80. Avataaar/Circle Created with python_avatars Gary Lollman says:

    You donโ€™t need to block off or seal those lines that you removed? Will they not be subject to contamination while left open like that?

  81. Avataaar/Circle Created with python_avatars Wallace Loper says:

    You better tail then about secure the lines. just saying

  82. Avataaar/Circle Created with python_avatars pork chop says:

    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

  83. Avataaar/Circle Created with python_avatars victormendoza871 says:

    Eric thank you!

  84. Avataaar/Circle Created with python_avatars burt bacarach says:

    Seems like a thin.say 1/8 inch thick piecs of stainless to sammich between the lines would work better.That way you'd be able to reattach the lines and not have to worry about the end floppin around and getting full of crud…..

    Reeeeeee. You didnt replace the schrader valves.

  90. Avataaar/Circle Created with python_avatars John Razmus says:

    Should pressure test b4 evacuation. If you have a leak you suck non condensables into system. Use N2 and refrigerant for elevated pressure.

  91. Avataaar/Circle Created with python_avatars phooesnax says:

    How to secure remaining lines??

    If you added a Rear Block Off, isn't that called a "Butt Plug"? (Dirty Dad Joke) =P

  94. Avataaar/Circle Created with python_avatars Orion3 says:

    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.

  95. Avataaar/Circle Created with python_avatars G Flores says:

    Pretty slick
    Eric o

  96. Avataaar/Circle Created with python_avatars Sandbag1300 says:

    Nice solution. Next time you get a chance, block off and tape the rear line(s) so that they do not get contaminants in them. That way, they can be used again if desired.

  97. Avataaar/Circle Created with python_avatars Geo Johnson says:

    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. ๐Ÿ‘๐Ÿ‘๐Ÿ‘

  98. Avataaar/Circle Created with python_avatars RV Shadow says:

    Same company that I got the replacement rear AC lines for my Town and Country from, no complaints. Everyone commenting about not blocking off the rear lines, they are no good and it is his winter beater, so I doubt he cares if the rear gets ruined or not.
