According to his profile, the OP hasn't been back since the day he asked the question. He left before the 4th. post....

 

My point, which I didn't explain, is that we all are learning, at some point, on this forum. It would be nice if posters with questions responded back with an answer.....if did or didn't help, if it was the "thing" they were looking for, OR if they found something better to assist someone else with the same problem. I WAS NOT LOOKING FOR RECOGNITION.

Nuff said.

 

If you r just looking for torque specs or some other basic info, grab the Chiltons manual for a Cobalt and copy it fo for future reference.

 

But anyway, the obvious, but to the neophyte not so, answer is way up there on page 1 of this thread. At first I did not know what to do with the links, you need some "internets knowledge". OK it's for 2007, but what has changed? I use it weekly, but then I put 1500 miles a week on my HHR

Those are only good through the 2009 model year.

 

Found this....

Note that those include the very rare 2005 HHR.......

 

Heres a good tip for everyone looking for any kind of info;

I checked my library for a HHR repair manual but they didn't have one but they have Chiltons.com as one of the many programs you can access, so I logged in there and pulled the hhr repair manual up and within a minute I had the breakdown picture of the 2.2L with the Camsensor location I was looking for.

The best thing is the gal gave me a broucher with all the programs they have and I can gain access to all of them from home just by using my library card number..
How sweet is that!!

 

It's been my experience that Chiltons sometimes tends to be somewhat generic in it's description of things depending on the vehicle. Glad it worked out for you but the factory service manual is a better overall resource.
