The Chevy Cobalt is General Motor's entry into economical, compact car market--a market previously dominated by the Japanese carmakers. It gets good gas mileage, has some "get-up-and-go" and is fun to drive. As with any manual transmission car, there comes a point where you might have to adjust the clutch.
Check the reservoir for the hydraulic fluid for the clutch in your Chevy Cobalt. If the level is low, this could account for the problems you've been having with your clutch pedal. Simply filling the reservoirs to the recommended level could restore the clutch's performance.
Examine the lines for the master and slave cylinder when the clutch pedal of Chevy Cobalt engages lower than the stock position. You might have a leak. Tighten all the lines, and keep an eye on the level of fluid in the reservoir for the clutch fluid. This may be all the adjustment your clutch pedal needs. If not, continue on top the next step.
Try to adjust the clutch pedal of the Chevy Cobalt when the clutch does not engage as it should. Look for the pivot point at the top of the clutch pedal. There you will see an 8mm bolt.
Loosen the bolt with a wrench, and pull the clutch pedal into the position you think might work--many report this is up. Test the clutch to see whether the clutch engages properly.
Replace the bolt that connects the transmission and the engine may be all the adjustment your Chevy Cobalt's clutch requires. Have someone step on the clutch while you look at the connection between the two. If they separate, you need to replace the bolt.
Check the wear on the clutch line--especially the rubber portion--in the Chevy Cobalt. If someone steps on the clutch and you see them expand, this could be the reason why your clutch is not engaging properly. When the rubber of the clutch line expands, it's restricting the necessary pressure the master/slave cylinder needs. Replace the line, and this might be the clutch adjustment you need.
