It does seem weird that there is that "slop" or "play" in the pushrod. I would venture to say something is wrong with your master cylinder. Was it the one out of the Cobalt, or a new one? If new, it could need to be "bench bled" first. If the old, then I would say just hook it all up, start pumping the pedal, and see if you get any pressure. I bled my clutch the old fashioned way. The Mrs sat in the driver's seat while I opened and closed the bleeder valve on the distribution block on the transmission. Down...up...down...up...LOL Worked really well! We got a ton of gross fluid out first, then it started flowing nice and clean. Great pedal feel. It was a lot easier than I anticipated.

Are you sure you are getting fluid to the MC? See my post about the reservoir fluid level.

So no fluid comes out with the clutch line disconnected and you manually pump the clutch pedal?

yeah, i saw that post, thank you. i remounted my reservoir to the top 2 holes (making it level), and i know there's fluid making it to the clutch because it's pulling it through that first hose before it hits the clutch cylinder

correct. see the play in the pushrod at the beginning of the video, i'm thinking that's a problem and why it's not pumping anything through.

thinking i might just replace the master cylinder but i am curious if anyone else's had that type of play in it -- https://www.carparts.com/details/Chevrolet/Cobalt/Replacement/Clutch_Master_Cylinder/2009/SS/RC31600002.html

I'm pretty sure my push rod jiggled around at the end too. However, I don't remember how much. I don't know how many times you've pumped the clutch, but it could also be that you have air in the line.
It seems to me that you're doing everything right. Bleeding the clutch--just like the brakes--isn't rocket science. I don't mean that in a negative way. As long as your master cylinder has fluid and you've pumped the pedal an ample amount of times, then fluid should in theory come out. If it doesn't, then it might be time to replace it.

Did you check to make sure your hard line isn’t clogged? From the MC to the trans. Saw a post earlier about someone’s hard brake lines from DF had blockage in them. Just a thought.

yeah thanks, saw that too, but i can't even get fluid to flow through the master cylinder to get to the hard lines
