2007-2014 Yukon Suburban rear A/C line replacement

How to replace the rear air conditioning lines, or hoses, with accumulator, receiver drier, add PAG 46 oil, evac, evacuate, and recharge r134a, on Chevrolet, GMC, Cadillac Escalade, Yukon, and Tahoe. This is pretty much the same process for all years from 1994-2014 model years with auxiliary rear air conditioning.

Great vid on the CORRECT way to do it. I been doing AC repairs for years, started out just watching to get ideas for aftermarket flexible line routing on these cars. Watched all the way through to verify my own procedure. Absolutely on point, true professional right there. 👌

[@LovenotHate130]

Thank you Sir I’m not a automotive mechanic but you’re video really helped me save $500 by doing it my you made it so easy it’s 95 out today so I appreciate you

[@danmanners7169]

Great video - used a reference and replaced our lines on a 2011 Suburban in about 2.5 hours.

[@Wisconsin4eyes]

About to tackle this on my 2013 5.3 Chevy express. Thanks for the visual.

[@wolleysegap9740]

Excellent fix, Rick. Nice and neat.

[@nealmont]

The price of 134a has just recently gone out of sight around here. Great video as usual.

[@RustBeltAuto]

Yes. Just got a 30lb a few weeks ago for 1.40 Oz. It doubled since last year. Did it go up again?

[@nealmont]

@@RustBeltAuto $360 for 30lb. here. The last 2 I bought were $120 2 years ago. $580 for a 10 pounder of 1234Y. Yikes!

[@RustBeltAuto]

@@nealmont maybe it went up again. Mine was about 230$. My supplier says if I get a price, I better get it now, because it can change tomorrow. Prices are going crazy. Construction is going through it too.

[@darronchadwick9630]

fantastic video got a quote of 3k to repair these lines from the dealer screw that i used your block off kit suggestion and some 134 and I'm back in business I owe you a beer

[@antonyotrapp7265]

Which line the rear line

[@darronchadwick9630]

@@antonyotrapp7265 yes the rear lines

[@busboyta]

My mechanic said about 1200. That sounds about right since dealers mark all jobs up like crazy. Thank you.

[@andrewfinley4543]

What are those kits called and where did you get it. My friends Suburban has the same blocked off lines and I wanna get it working.

[@MikeSmith-nu9wt]

I took the auxiliary ac box off my smashed 09 gmc denali , im trying to find 63 ft of ac lines , im putting it on the side of my bucket trucks bucket , hoping it blows decent air/wind , im not expecting much cool , but i gotta try it , i put one in my jeep cherokee , cause i didnt want to remove the dash ..i use the hevk out of those auxiliary airboxs , there all self contained fan and everything , makes them handi , zero turn lawn mower homemade cab and ac is next , its more involved i gotta mount the ac compressor on that one ..

[@PaulThomann4555]

I recently (07-11-2023) paid $1,747.34 at my local GMC dealer to have lines replaced. 60% labor and 40% parts. Just FYI, wish I would have watched this first!

[@desaleasmaa642]

Thanks for sharing this video, I wondered where is low pressure switch located I can’t locate on my 2014 Gmc Yukon xl that would helpful.

[@RustBeltAuto]

@@desaleasmaa642 usually on the accumulator, or low pressure line.

[@user-zl4yg9ym6f]

I bought an Auto Cooling Solutions kit for a 2012 GMC Yukon SLT (standard wheelbase, not the XL). I am not sure if the brackets for the side steps are bigger on the XL or what, but there is no way in HECK these line will fit through the brackets without taking the old lines out. This video makes it look misleadingly easy to get those flexible lines through the brackets without taking the old lines out. Just FYI to anyone else viewing this video.

[@RustBeltAuto]

Yours must be a little different.

[@user-zl4yg9ym6f]

As an additional follow-up, I also found that separating the refrigerant lines from the rear expansion valve to be quite troublesome. They do not come off anywhere near as easy as described/shown in this video. I am mentioning this not as a criticism to the OP but rather as a warning to others facing this same repair. Check out other videos as well, some of which mention this. The metal stud passing through the aluminum plate is a source of galvanic corrosion, and is not easy to break free. I spent hours and hours on this yesterday, including an entire can of penetrant. I ended up having to use an air hammer to separate it. And in doing so damaged the expansion valve which I now have to replace as well. Again, not criticizing just want to warn others this is not as simple as seems. I consider myself better than average at DIY fixes and have been doing my own auto repairs for years. But this is one I wish I had passed on. As advice to others, I might recommend trying to see if you can get these line's released BEFORE you order your own parts (my lines were almost $400). Now I am in for $400 for lines, and now a new expansion valve and two days of my time. In retrospect the $1k quote I got for the line replacement might have been worth it.

[@spelunkerd]

Well done, great demo.

[@RustBeltAuto]

Thanks!

[@buddy1976]

I used pool noodle as cushion protection around any metal so it wouldn't pinch the lines

[@RustBeltAuto]

@@buddy1976 those are flammable, and don't like heat, and chemicals.

[@wwcj0000]

I appreciate this. Thanks

[@Saint696Anger]

at 14:00 flare nut wrench would have come in handy, I think I'm going to order some

[@pastrana37]

that's a great video thank you for share.Question where I can buy those flexible line, any feedback will be appreciated,i'm driving a 2007 gmc yukon denali

[@RustBeltAuto]

@@pastrana37 people make, and sell them on ebay, and amazon. You just need to make sure you get the right length, because there are a few different wheelbases.

[@pastrana37]

@RustBeltAuto ThankU So Much Yeah I just Foud it Auto cooling Solution I'm Taking to Them Right now,ThankU Very Much I Really Appreciate you fast Response Have wonderful Day ✌️

[@northpoint1039]

Seems like they would put some rust inhibitor on the lines where they meet the plastic holders. They always seem to rust there first because of moisture between the plastic and metal. Good video. Thank you. Wonder how much it costs to evac a system at a garage? Or perhaps just take the car "out behind the barn" and ... :)

Good video, heart made one Where to buy one for Dodge Journey 2014 R/T AWD 3.6 L Aluminum line leaking ia 5/8" R134a running in. Thanks for helping

That's an amazing story.

[@busboyta]

Can u plz put a link for the air conditioning hoses? I asked my mechanic and he said he would consider doing it your way . I just need to know where I can get the hoses. And what are the names of the hoses. I’m clueless ! Thanks 👍

[@RustBeltAuto]

I think my brother in law got them off of Amazon.

[@ramiro896]

What is the torque spec for the 13mm nuts

[@RustBeltAuto]

If it is 8x1.25mm, I would guess about 12ft lbs.

[@busboyta]

How much did you charge for the fix?? Thanks. If I was handy I would definitely do it your way.

[@RustBeltAuto]

I don't know.
