Just did this on a 2011 JL Wrangler to replace rusted/leaking lines with new ones. Couple things I learned: 1) Old rusted lines at press in fittings don’t allow a quick disconnect tool to work (had to use two picks). 2) To get clips out manually, had to soak clips/fittings in PB blaster and work them to loosen the clips. 3) Scraped out the fitting edges for a while around the line press fit to get rust out and PB blasted again. 4) used one pick to press between line & clip bump out to push it outward so I could hook clip from outside with other pick. Longhandled needle nose pliers are a must for grabbing clips, etc on this job. Here’s where it got even harder…😢 5) after clip removal Fittings at radiator were rusted in place and would NOT come out… Kept at them with PB blaster and grabbing metal line with Longnose pliers and cranking back and forth to eventually pull the lines free. Was tough and took at least 10 mins of wiggling forcefully while pressing outward on the line… PITA. I heard some people recommend cutting lines and using a deep so it to remove fitting body… my fitting body just spun near radiator as it seems like a compression fit at radiator tube… I didn’t want to mess it up so left it… spinning that fitting nut without cutting lines might help to break the rust free from the stuck line … but I just kept using the long handle needle nose and wiggling and pressing til it eventually popped out. Removing lines at trans much easier. 6) Had to do some slight bending of the new lines to get them in correct shape and fit so they didn’t rub on anything or each other and didn’t have odd angles or tension when fitting them into the clip fittings… you want the line end to push straight in and pop in all the way so the clips can be installed and hold get in front of the line end flanges so the lines wont pull out. Test pull these after you get the clips reinstalled. 7) Reinstalling clips was sorta a pain because you had to make sure the lines were fully seated so the clips got in front of the line flanges to hold them in… the clips have 3 bumps or spots the snap in to holes on the fitting clip channel. Hard to see but the center clip goes into the short hole (channel) and the end of clip slide into the longer channel hole openings. 8) Test pull on line and make sure clips are fully seated into fitting as evidence by clips being full down into the channel and not protruding (needle nose to make pure they are pressed down fully.. if not the line flange may not be all the way pressed in - must press in straight which might require a slight line bending). 10) once all closed in a pull tested, start engine and check for leaks. 11) no leaks push plastic cover back over clip fittings (might need to use a bent nose long handled needle nose pliers as I had to put tip on either side of plastic cover and give it a hammer bump to get covers to seat fully. 12) Install line plastic retaining guides so lines don’t rub on anything or each other, hit anything or press against any other parts. 13) replace the amount of fluid you caught in pan when you pulled lines.

perfect video. I love it when people just start working right away, and save the talking for as they work.

[@gregbloch2765]

How much would this cost in labor

[@DoubleoP]

​@gregbloch2765 Depends on how much of a rip-off artist the Mechanic is.... I just bought both of those fittings of Amazon $33 Ac- Delco. Half hour labour charge is in order max.

Great video. I'm working on a 2006 GMC Sierra 1500 but it's probably a very similar set up. I will find out when I get under the vehicle later today. Thanks for the information.

[@mikedavidson7470]

Thanks for the video!! Just changed both of them on the trany and no more leaks! And it was easy. Get you a cheap set of picks, makes getting the clips off easy.

[@DirtyNate98]

Tip for 98 s10, the upper fitting on the trans is really really tight. I unbolted my flex pipe to give me room and will be unbolting the cab on that side and will jack up the cab to give me room for a ratchet. I have to weld in a new cab mount anyways so might as well do it all at once. Also for some of the fittings I used a sawzaw to cut the line that wouldn’t come out, in order to get a socket or box end of the wrench on. Used pb blaster for a long time. Supported the radiator with a wood block since my mount was rusted. And slowly slowly torqued the fitting of as to not crack the plastic radiator. If you can spray pb on the fittings days in advance.

Excellent explained Video

[@jameshaney4494]

Nice video. Well done.

[@chickenstick2109]

Thank you!

[@hutfrd]

Kinda forgot to tell us to put the clips in first cuz on mine, I didn’t. And now I can’t get them on. So it’s a good thing I didn’t know what I was doing wrong til I saw how you didn’t tell us how to do it right so thanks!

[@DirtyNate98]

Did you not watch the whole video? you see he has the clips in as he pushes the line in clear as day at the 3:00 mark. It’s the whole point of the quick connect fitting to be able to do that… same as fuel line quick connectors and so on…

Took me 5 hours to do that today on the lower Inlet. 2013 Acadia Denali. Couldn't get the clip (3 flew away) in the nut. New clips assortment $18.00 Yes, I had a Pick. Wasn't sure that fitting came out of the rad. I ended up putting the pipe in then the clip. Put a small rad clamp on it just to be sure.

[@shawnrahm6254]

Thank you boss I'm going to get at it right now

[@how2af263]

Did it work?

[@SmOoThYwOoDy]

How much transmission fluid needs to be put back in after changing that same fitting? Does a lot come out when changing a new quick connect fitting? Just wondering how many quarts I need to buy before doing this.

[@j.r09160]

I can't find the oil cooler line online for my 99 intrigue

[@killemtoenjoythesilence]

Thanks for the reference. You can actually just replace the o ring though. You can pick the old one out and get a replacement from an auto or hardware store. I've just done that myself. I replaced the top one on the trans cooler about a year ago and it's still doing just fine. I've just changed the bottom one a few minutes ago but have no reason to believe it will fail. It was actually pretty easy and both repairs cost me a buck 50.

[@bmindful]

Do you have the part number for the o ring? I was going to do what’s being done in the vid before reading your comment. I believe it’s just the o ring now that I think about it

[@killemtoenjoythesilence]

@@bmindful unfortunately I've lost the packaging with the part number but the ones I use are from the plumbing section at Lowe's. They are an outside diameter of 0.500" or half inch and a thickness of 0.075". It's a standard size they stock. If you remove the fitting and carefully remove the old one with a pick you should be able to match them by eye with no trouble. Just remember that the old one will of course be a bit compressed so your replacement will look a bit thicker. Not a huge difference as they do have some on the rack that will be considerably thicker. You don't want those as they will not fit. As long as you use a bit of common sense as far as matching it to the old one you should be just fine. It's a pretty easy fix. Good luck. Any other questions, feel free to ask.

[@bmindful]

@@killemtoenjoythesilence Greatly appreciate the reply. I’ll take that advice of yours and see if I can fix my car. If I have any problems I’ll meet you back here

[@kaydee6883]

Will topping off the fluid make the trans slip when doing this ??

[@liveandletlive2894]

Is this the same for a 96 gmc sonoma?

[@chrisstromberg6527]

Thanks, this helped!

[@maxdeniel]

Thank you very much for sharing your knowledge. I have a question, in my Dodge Avenger 2008, one of the cooler lines just disconnected it self from the fitting and all the transmission fluid spilled out... then I bought some universal o-rings and installed the metal line back into the fitting, and of course pour more transmission fluid. So the question is, is there some chance to the metal line to disconnect again from the fitting???, do you recommend to change the whole cooler line?

[@jimblack120]

best bet for you buy a Bus ticket

[@Prof.Squarepants]

The oring's can be replaced Iv'e done it many times to many different Chevy models this will save you alot of money if you were to replace all the fittings on the vehicle. Its about 30 bucks for oil and trans cooler fittings as opposed to under a dollar for the orings.

[@drzg2640]

Ryan Shepard cause it’s a 6 dollar fitting 😂 jus change the whole thing

[@438marcus]

@@drzg2640 lol and it takes more work to replace just the o-ring lol

Same procedure for Hummer H3?

Hopefully this will solve my transmission leak problem!

[@robertmoreno9876]

So when you put the new one on you not supost to take the clip off. The hose just slide in

[@vondalewright4128]

What do you do when that line is leaking ? O ring ?

[@JohnEidson-dn7kp]

That's the way to do it straight to the Point, but you left out a very important step. You gotta put the o ring back onto the fitting before you slide it on there. You can't just assume people know that

[@larrygeorge5220]

Is this different on a Chevy half ton 2 wd

[@debcampbell1640]

Why was it so hard to take the fittings out of the radiator, and put them back into the radiator after following all the directions.

anyone have the part number for the other fitting he didn't show how to replace lol

[@jacksmith3189]

Part number for clip?

[@joebrown967]

If these are leaking would it cause a pressure issue? Mine drips and sometimes I get semi-hard shifting.

[@peterm3333]

Yes it can. As the fluid leaks by the ring, it also allows pressure to escape and possibly causing shifting issues.

[@joebrown967]

You don't need to do transmission oil change after this?

I didn’t change the oil.

Buenas noches como se llama la pieza que cambia me acaba de derramar todo el liquido el silverado 2001 y quedo neutralizado lo apague inmediatamente y mañana quiero cambiarlos y rellenar de aceite ala transmisión

[@jeremymorgan5009]

Will it over heat if this bolt is leaking an not tight

[@how2af263]

I’m sure it wouldn’t be good. The reason why I changed is because it started dripping on my driveway. I didn’t drive the car until it was replaced.

[@jeremymorgan5009]

Ok well I haven't got up under it yet but looks like it's leaking there an that's only place I see leak as it's over heating nothing in oil showing head bad

[@fabianarredondo2572]

are you supposed to leave the grease in there?

[@how2af263]

Yes

[@RomarioZ11]

So how do I get the new line back in if it doesn’t want to go in? And yes it’s the right size

[@Danny-ow7hl]

Why does it have grease inside?

[@chickenfoundation9323]

How much fluid came out?

[@how2af263]

I would say little less than a quart came out when the line was disconnected.

[@trentbuckle6880]

what year and make was your vehicle?

[@how2af263]

Hello thanks for watching. The car in the video is a 2011 Chevy Impala LTZ 3.9L.

[@Whit_Siever]

This looks like the Chevy Uplander minivan I need to look at. The hex bolts aren't bad the hose itelf has excess leak downline where metal coupling meets nylon hose.-As far as removal, can I just unbolt the hexes on each end and transfer them to new hose separately on the bench or do I HAVE to unclip hose before removing hex's?-(Also had a different Buick that the A/C was leaking, compressor good but one hose had same metal pipe coupling into rubber hose, so shows what GM knows about making their inline metal to rubber couplings durable.....)(and of course it was an all-in-one hose ASSEMBLY so even though only high side hose was leaking, it took the perfectly good low side hose with it, more GM logic)

Man those fittings are garbage. Some engineer needs to take himself out back and commence the beating of a lifetime for wasting everyones time and money - as fancy as he got, he didn't find ten seconds of greater reliability over an old npt/hosebarb style fitting. I think the el cheapo compression fittings I use under my kitchen sink are quicker than that [and they probably last longer too].

There was definitely a mechanic fucking the guy who designed this fitting’s wife.
