My Dad just ran my VIN and he said there is nothing out for my car right now...I have an 08 that was built in April of 2008...

streat screamer

my bracket broke and the piping shifted in the engine bay and got smashed between my engine and the hood. I already had bsr/ppc,hahn 3",and hahn cold air intake, so i figured it was a perfect excuse to get the hahn piping. Installed and drove the car, about 50 miles later the engine light comes on. so i end up replacing the MAF sensor,& MAP sensor (first one in the contry)and buy a scanner to reset computer. Car seems to run fine again for about 50 miles till the light comes on again. Missfire codes everywhere.

So i take the tune out of the car, change the plugs drive about 50 miles not only do iget miss-fire codes but i get a U0073 code that i dont what the hell means. So I start to take it back to stock and discover oil in my turbo. Did i just discover my problem or a catastrify? And what is the next step?!?

I looked at a 09 SS/TC at a dealership. The charge air pipe fell out of the "stud" and the salesperson didn't know anything about a TSB (PIP-4485). I wasn't sure if it was a bolt or stud, but I popped it back into place. It seemed like they changed it into a rubber grommet so that it would just clip onto a stud. That looks like a problem down the road. Has anyone found a sure-fire fix for this? I popped it back into place in front of the salesperson.

Nonetheless, the plastic charge air tube was STILL rubbing against the A/C line. Any ideas?

did u completely miss page one of this thread??? zip ties are the fix man, GM won't do *** all about it so either get better charge piping or suck it up and zip tie it.

metroplex

I saw the pics but that still doesn't move the air tube away from the A/C line. The one at the dealer was rubbing that line badly even after I moved it back into place.

Is there an aftermarket pipe available that clears everything?

It seems odd that I had to fix a new car at the dealership in front of the sales person.

Have you checked to see what is involved with the TSB? GM obviously knows about it, otherwise they wouldn't have assigned a case/number.

widowedeight

yeah i am at 24500 miles and haven't had this problem yet either....

metroplex

Is the paint on your door (near the lower part of the A-pillar area) still intact? I'm just curious if there is a correlation between the Cobalts with properly attached air tubes and other defects.

1WhiteSSTC

it's moved far enough away and secured with zip ties to prevent it from ever touching the AC lines anymore, several members on here have my ziptie mod and have never had any issues since doing it.

Highbeamz

If you use black zip-ties you might not even notice they're there...

metroplex

When I repositioned the pipe, it was still jammed against the A/C line. I don't see how the zip-tie would have solved that issue on this particular car.

09CobaltSS1

only 1300 miles on my 09 and mine just broke. freakin p.o.s. charge pipe

metroplex

Here's a pic of the stock clip on my 09 SS/TC:



Is this what everyone gets from the factory?

2ndWhiteSSTC

that look slightly different from mine, it appears that yours has an extra piece that would keep it clipped in, maybe it's the piece that was on mine and fell off........all i know is wat i posted in the original pics on page 1, there is a way to make it work and unless i'm standing right there i can't point it out any better than my pics. FYI, u can't use a 2inch ziptie, u need like a 3-5inch ziptie if u intend to get it attached to anything solid.

metroplex

I noticed the 09 SS/TC's in the lot didn't have this clip or the rubber insulator for the fuel injection pump.

2ndWhiteSSTC

yea i'm not sure why GM did that, all I know is that my zip ties do wonderfully, u just need long enough ones to attach to something solid, if u still are having problems I could go back and take new pics and see if they help at all, let me know.

Mazdaboi318

mine just broke

metroplex

Yes, new pics would definitely help. I might use zip ties to reinforce it.

Jaemon52

I still don't know wtf they were thinking with plastic charge piping. They need to do a gm accessories thing to solve this if they don't want everyone going hahn.

Terminator2

If you look closely at the stock pipes you can see that AEM makes them for GM. You would think that they would be better designed and better quality.

swazzees

so its random if we have to zip it down on an 09???
nice

Terminator2

Mine never popped loose but I ended up blowing a small hole in the rubber hose coming out of the Turbo. I would get aftermarket chargepipes if you can afford them.

RBC

Mine broke aswell. The plastic clip on the charge piping that goes over the stud is what broke on mine so I really had to zip tie it. Mine looks more like the picture on the first page than the last picture shown, but I don't have the little rubber peace on the top. I have charge pipes ordered but if there's a TSB on it I am going to go get it fixed so I have a perfect stock part to put on if ever needed. Mines an 09 sedan.

SilverSSedan

ok, i look at these pics, and it looks like you have a picture of the insulator around some wieres, then you got a picture of a smooth rubber hose clamped to the intercooler, maybe i'm blind, but can someone maybe put an arrow at where were looking from one of the whole engine bay pictures...?

2ndWhiteSSTC

This should help
