Help! I have a minor problem with my cobalt ss. It is related to the intake system. while swaping out the stock air filter for a k&n filter i noticed something disturbing. The elbow that connects the airbox to the turbo has a nipple on it which houses the crank case breather hose. this nipple has broken off!! i have no check engine light but i dont want debris getting absorbed in the crankcase. i have made an extension to the nozzle so i can put the hose back on. its not 100% yet. it looks like the plastic got too hot and just broke like it was brittle. any ideas on where to get a new elbow? or if i need a new elbow?

 

To the op, you have a warrenty, just take it to the dealer and have them fix it.

 

Unless your engine got like 400 degrees or more it didnt affect the plastic also the intake hose is a high strength high melt plastic and the flat area is not to clear the hood there are other things higher on the engine than the intake it makes the air flow faster so for all of the people thinking of changing that it wont be better dought will have as much airflow with aftermarket round piping.

 

That would of been the first thing that came to my mind. Dealer time.

 

i guarantee its the same issue mine had that caused this. as the motor torques the plastic duct is forced out of the holder and moves around. on mine it broke the connector off the fuel pump housing.

 

its going to the dealer its just sunday@!! i have no idea how the hell it broke! i opend the hood this morning and bam there it was. the plastic seems real pourous and shitty quality where it broke off at. This part should really be metal. i almost want to fix it for gm. but oh well. ill just take it to the dealer tom.

 

Ok this is from Service info from GM, i just wanted to inform people so this doesn't happen again, that breather hose is supposed to be removed from the intake while removing the air filter or working on the intake tube!!!!!!!!!!!!!!!!! it is a simple disconnect procedure.If you look at the pic it is the cream color tab that you press together to release tube.Hope this helps people out.






This step applies to the Q release type connectors ONLY. Release the fitting by pushing the tab toward the other side of the slot in the fitting.

 

thats helpful info..

 

Wow, this thread became interesting real quick.

 

Yep figured he broke it noway was it heat that damaged it but wasnt going to say that but what do I know only have been a plastics automotive and custom process engineer for 20 years or so thanks Cobalt/TC for the info on the airfilter change.

 

No prob just want to prevent this in the future, that is my car in the pic i found that out when i tried to check out the filter seemed a little to tight, so i checked it out on SI and found that little info.

 

well you could be right but i was fairly careful when removing it. do you know the part number on that part?

also the point still remains if it was metal it wouldnt have broke

 

not sure on the part number, yeah i understand, stuff happens it shoudl be metal but what ya gonna do ya know

 

Also how do remove that from the intake elbow. wheres the release?

cobalt ss/tc good support man. when you get a chance can you post a picture of how to unhook it. i saw the directions but i still couldnt get it.

 

there reposted with instructions on how to release the connection

 

Probably be a good idea for anyone who doesn't change there own oil to tell the techs to leave the air box alone they love to pull them off and sell you a air filter inflated price of course. And yes I hate some plastic parts myself they can be made as strong as the maker wants with the right polymers and additives like fiberglass some parts are made to fail so you have to buy a new one plastics do not take well to lateral force in thin areas the intercooler and intake pipes are a good example of being made with filler it appears very strong to me not crappy like on older cars like my 92 mustang which has a new stainless intake now with k&n filter my cobalt ss/tc is staying stock until I find out anything is better flow I think it will be found out the flat tube has better flow than any aftermarket round piping just my opinion so take it or leave it.

 

Yeah i feel we will be seeing more of this!!! maybe they will come with an updated part on a campaign. Not sure about the factory intake being better then aftermarket, i can fit my fingers around some of the intake parts, gotta remember they have to meet noise reduction levels too so it is pleasing to everyone.

 

Yeah you are probably right about the intake hope it's better than my mustang had a tiny pipe within a pipe silencer I was more referring to peoples concern about the intercooler pipe where it goes flatter over the valve cover. I've seen performance pipes that had this same feature and it was supposed to make the air flow faster I also noticed that the flat area was wider than the round area so flow should be pretty good I think .Not sure if it was to clear the hood or not if you look at it the air cleaner housing is a cpl inches higher than the pipe is?

 

you should make a "how to" thread out of this

 

That's good to know, thanks for posting it up.

 

FYI for all wondering what thats for, thats part of the PCV system

 

What is the K&N replacement filter for the SS/TC? I've checked on their website and all they have listed is an oil filter. Is it the same one as the Sky/Solstice? I was worried that it might be a different shape...please help because I'd love to get a K&N air filter ASAP!

 

33-2311 is the number for the replacable filter for the 2.2 Cobalt, the lower housing on the 2.2 & 2.0 are the same so it should fit

 

That is great to hear...thanks for the help...can anyone verify this for me?

Also wondering....if the replacement filter is the same for these, would the Typhoon kit for the 2.2 also work for the SS/TC? This is PN 69-4515TS. Thanks for the help!

 

The typhoon kit will not work
