Question for those with the failed AC hose

So my warranty just ran out, wonderIng if anybody thought of a solution or cause for the AC line failure and if anything can be done to prevent it. Not sure what causes it. I'm sure I could find it with an hour of searching.

 

Is it movement that cracks it? Material just degrades? any ideas on why it fails?

 

I just don't want the AC system opened up from the factory seal and if there is anything I can do to prevent it, such as reinforce it some how, I'd like to do it.

You can't prevent the failure. It will happen. Flex seems to be the issue as GM tried a bracket with minimal success. GM has a new hose that is another prolonged repair try. Hope this one works better than the last band-aids. Run it until it fails and go for goodwill coverage.

Seems that most of the guys that have had the issue did have the radiator issue that requires the removal and replacement of the radiator moving the A/C line. Several had the A/C line crack thereafter. Seems it is a marginal piece and anything can promote it to crack. I had my radiator done under warranty along with the thermostat as per the TSB and I have figured its a matter of time for the A/C line depending on if they yanked on it.

GM tossed the bracket in the trash 2 weeks ago. The newest hose nolonger requires the bracket. Goodwilled me again 100% at 55k miles so I can't complain about the 2nd failure of the same hose.

Not sure where you heard that from. The service bulletin is still active that states to install the bracket. The weight of the muffler on the line as well as engine vibrations caused the lines to crack. Installing the bracket properly will prevent future failure of the line.

I just replaced the line today myself and installed the bracket.. It was a total pain the rear. Definitely helped having a helping hand from another person. I just couldn't fathom paying the dealers price. They told me it'd be like $500. I bought the hose and bracket for $85 online. Haven't charged it up yet.

Part numbers? What hose is it? Anyone have a picture of the failed hose in the truck?

Don't worry about part numbers. Just make sure you get the latest design as it is a departure from the other band-aid bracket fixes and I am sure it will be revised too as needed.

If only I would have known about this "new" re-designed hose before I ordered the parts a month ago and installed yesterday. It is not a fun job. Hopefully with the new line and bracket it can last longer than the original. Original went about 40-45k not sure exactly, and failed in October. I now have about 55k (didn't change it til i needed AC).

Are these A/C hoses failing on all the 14-15 trucks? Or is it just wide spread? If so I guess i better start saving now for when my fails. I'm at 22,000 now only 1 year and few months till factory warranty is up.

14-17. I would say very wide spread once a vehicle hits 50k miles. GM is taking care of people who ask for good will coverage.

I'll have to remember that if I have problems down the road. Thanks.

I hope mine lasts! I usually drive 5k miles a year but sometimes more if I take the truck instead of the car on vacations so it will probably be a few years down the road before mine goes out.

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
