Hey guys,
well, in the mists of selling my cavy and picked up an 05 ss/sc. Now i noticed when i drove it home from the dealership that theres a clicking noise coming from cat/exhaust after its been warmed up. I hear it right after the car is parked, or when sitting at a light.

Is that normal? Or is there a recall/fix for that. I also noticed the squeak in the rear susp/deck. When i get a chance, ill pull the deck lid apart and make sure things are good. Not to mention, it feels like the drivers seat is a bit loose. It feels like it moves when u stop. Weird, anybody else have that?

Thanks for the help. Guess after 11years of cavy... i'm a NOOB again!

 

Mine clicked but that was only when the header gasket was cooled down, like sitting at a light and ****, it could have a crack just like mine did, does it do it when you first start her up in the morning or whenever?

 

Mine makes a tapping sound after I shut her down. Almost like a baseboard heater heating up and cooling down. It has done it since brand new.

 

Lots of cars do this. At least many that i've owned have.

 

Yeah, I'm pretty sure it's normal. Things expand/contract with temperature.

 

Mine never did this until I picked up the SS exhaust, it gets annoying as hell, no matter what. Once my cars warmed up it clicks every half a second. it's extremely dumb... and I can't take it to the dealer because they wouldn't warrarnty an SS exhaust on a 2.2L

 

The sound your exhuast is making is 100% normal. The stock resonator makes those while cooling down. And the clicking noises the other posters were hearing was either the trunk latch self test or the fuel cap self test. All 100% normal sounds.

Edit: It's not so much a cooling down noise as a when the resonator is hot noise. Most people just notice it on cool down.

 

That may be true but like I said, the noise has only showed up after I installed the SS exhaust and it constantly ticks once heated up. not just every now and then, all the time.

I wanna know if the SS exhaust is too close to something under the car that is not suppose to expand past a certain point by heat.

 

totally normal

 

Unless you have a non GM, non GMPP exhaust it's going to make that sound. My car made that noise when I had a stock exhaust on. You may have an SS exhaust, but until you go aftermarket or GMPP, it's still a stock exhaust.

 

My exhaust does the same thing, no worries. also make sure your seat lock is completely pressed down, I had the same problem I made a stop at a light and I flew forward.
I was kinda funny. Push the bar down all the way until it locks the one that needs this finessing it the lock that is closest to the center consol. that the one that gave me the trouble. just wobbled it in and it works fine now.

 

come on ppl use the search button b4 u post pls there are tons of threads on this

 

all the stock exhaust systems on the Cobalts do it... the cat-back systems, including the GMPP one do not.

 

Yes, I reserved my "you're a fucktard" comment on this one too. It's okay RedBaseBalt has only had 1200+ posts to figure out how to use the search button. If he hasn't figured it out by now I figured I'd help him out.

 

I do search thanks, and it doesn't help sometimes. and I've got 1600+ posts thank you.

 

So I guess the + didn't cover anything over 1200?

 

Wow that make so much sense! i was always wondering what that locking/clankin sound was. i knew it wasnt exhaust... so it just makes sure the trunk is locked?

 

I have had the same clicking noise also. but from what i have read and what the dealership tells me it is noting to worry about.
