I've been a mustang guy most of my life, but I've researched the Cobalt SS/TC the past year. I picked one up, finally, a couple of months ago and damn, I love this thing.

Great gas mileage (not as good as the cavalier I sold), and awesome horsepower available. I was on this site the same week I purchased it and all y'all convinced me to go GMS1. It was installed the next day.

A few things I've run across the past month:

As mentioned in several threads, make sure the TMAP in the cold charge pipe isn't grounding on the AC compressor! I wasn't having this exact problem, but occasionally I was getting a random missfire under load. I finally checked it a few days ago and noticed the TMAP bolt was loose. It was just flopping around. Thanks GM technician! I tightened it down and no problems since then.

Also, the vacuum line that runs from the cold-charge piping to the intake manifold has a bad habit of rubbing on the fan shroud. I re-routed it because a few thousands had already worn off the hose. Just run it behind the AC hose so it won't hit the fan shroud.

Thanks for all the information available on the site! Long live the SS/TC cobalts! Down with mustang 5.0's!

PS - The oil leaks are pissing me off. DIAF GM.

 

Welcome!

 

Welcome I also have the K&N drop in and I will be having the GMS1 installed soon.

 

Welcome!!!

I sold my Camaro Z28 and got my 09 Cobalt SS I love this car and have no regrets getting it!! oh yeah did I mention its super fast, great gas mileage and looks sick!

 

Welcome to the family. After a year of ownership, my balt still puts a smile on my face everytime I drive it

 

Welcome to the site. Glad to see your enjoying the new car.

 

once you go ss/tc you dont go back

 

I lost my ass and traded my 05 Mustang with everything but cams in it for my cobalt tc, I wanted one the minute they started being built but no dealers up here would order me one so I went with the Mustang instead, after rebuilding the diff 3 times with 10000kms on the car I quickly realized that although it looked cool and everyone loved it the car was after all just a ford..... I have already put half as many miles on my cobalt in 6 months of owning it as I did the mustang in 3 years and have not had a single issue with it. It is as fast as the mustang gets 20mpg more, better brakes, better handling, under waranty and after GMS1 I dont see myself needing or wanting to spend anymore money on the car, The mustang I paid $21000 for and dumped $10000 into got 18000 on trade for the cobalt everytime I get behind the wheel of my cobalt I spool the turbo and fly, everytime I drove the mustang I would be waiting for a tow truck or drive it so lightly so it wouldnt break it was to the point where it wasnt even fun to own anymore, I did have one last run with two srt challengers one 6 speed one auto the auto fell behind after about 130mph the 6 speed couldnt shake me I stayed with him till 155 or so pulled into the dealer and traded it for the cobalt lol

 

I like my balt, but I'm going to have a hard time not trying to afford one of the new 5.0s.

 

Pics?

 

I was 3 sheets to the wind when I made this post, it looks as though I was a little excited, with my exclamation points and all.

I have one pic I took with my crappy phone:



I'll try and get some better ones when the weather lets up.

Thanks for the welcomes!

 

Black is the best color.

 

looks nice.

what kind of Oil leaks do you have??? i got 105K on my LE5 and no Oil Leaks. im just curious

 

I've had it into the dealer 3 times for oil leaks. Once for the crank seal and 2 times for the driver side of the head. They replaced the cam position sensor the first time, but now it's leaking again. Probably the cam end plate or fuel pump. I'll probably end up doing it myself with some Toyota FIPG because I can't trust someone to do it right.

Just got done fixing more rattles... it's still a blast to drive, though.

Edit: The cavalier I purchased new in May, 2002 had a 126,000 miles on it when I sold it. The 2.2 Ecotec had no leaks.

 

oh so you must got a bastard form the plant. that blows. hope you can get it all straight.

 

i went from a mustang gt to my cobalt ss/sc and i am in love. better mpg and its actually faster than my mustang. wish i could afford a tc but my sc is awesome! there is always twin charging down the road.....lol

 

I have my 07 Mustang GT and 09 SS/TC. I like the SS/TC better for driving ergonomics and fun factor. The Mustang is built a lot more stout and doesn't have as many quality issues as the Cobalt.

 

Yes it is. Its also the hardest to keep clean and shiny Took me forever to find the right combo of products to keep it lookin' good lol

 

nope. yellow is better

 

Black hides lines on a car. I hate it. Just my opinion, though.

 

I have that leak too .... it this one on my car

--------------------------------------------------------------------------------
Condition
Some customers may comment on an oil leak.

Upon further investigation, a technician may find oil leaking from the high pressure fuel pump area.

Cause
This condition may be caused by a camshaft cap that is not sealed correctly to the cylinder head, causing oil to leak out.

Correction
•Verify the customer's concern.
•Remove the fuel pump. Refer to Fuel Pump Removal in SI.
•Remove the camshaft cover. Refer to Camshaft Cover Removal in SI.




•Remove the camshaft cap (1). Remove all excess sealing material from both surfaces.




Note: It is critical during installation to ensure the bearing rear cap and cylinder head alignment is correct and the mating surfaces are flush.

• Ensure that all sealing material has been removed from the components and the sealing surfaces are clean and free of contamination prior to applying the sealer.

• Install and align the rear cap within 20 minutes of applying the sealer.


•Apply a 2.5 mm (0.1 in) bead of sealer, GM P/N 12378521 (in Canada, use P/N 88901148) to the cylinder head at the number 6 intake camshaft rear cap mating surface.
Note: Apply the sealer to all locations centrally locating the bead on the rail.

• Run the bead to 5 mm (0.2 in), dimension "a", as shown.

• Where the cap ends on the perimeter rail, extend bead approximately 4 mm (0.2 in) beyond edge of cap.

• Run bead, dimension "c", 32 mm (1.3 in) from the edge of the cylinder head as shown.

• Run bead, dimension "b", 20 mm (0.8 in) from edge of cylinder head as shown.


•Install the number 6 intake camshaft rear cap.
6.1. Tighten the cap bolts evenly to 5 N·m(44 lb in).

6.2. Tighten the cap bolts evenly to 10 N·m(89 lb in).

6.3. Back the cap bolts out 120 degrees.

6.4. Tighten the cap bolts evenly a final pass to 10 N·m(89 lb in).

•Install the camshaft cover and gasket, GM P/N 12609291. Refer to Camshaft Cover Installation in SI.
•Install the fuel pump. Refer to Fuel Pump Installation in SI.
Important: When installing the fuel pump, install a NEW high pressure fuel pump O-ring (GM P/N 12600313), high pressure fuel pump gasket-to-cylinder head (GM P/N12595951) and high pressure fuel pipe (GM P/N12615401).
