2005 Chevy Aveo timing belt

Does anyone know how to put the motor back in timing on a 2005 Chevy Aveo? My serpentine belt shredded and got inside my timing cover and I think caused the timing belt to slip. I know how to adjust a normal belt, however this one seems to be different than anything I'm used to.

because peices of the serpentine belt were stuck between the timing belt and the pulley and its not hardly running at all, we know that the timing is off for sure, just don't know how to put it back.

I don't understand how the drive belt could have gotten inside the timing belt components without destroying the timing cover. Is there more damage to the cover that we should know about?

A little more info would be helpful....
Did you replace the belt or just take if off & line up the gears? Where did you get the info for the timing marks?
If it was running before & not now then you missed something. Does it have spark, fuel pressure & injector pulse?
The cam sensor is right by the cam gears, double check that area & connector very closely.....

we got the info from a chevy dealer on how to line up the marks. When the serpantine belt started to shred, I could hear it, then I drove it off the road and called my father which is a mechanic and he had told me that I could try to get the car off the turnpike, just to be sure and stop when the belt finally gave, because the car would over heat, so I started the car back up and drove slowly on the sholder for about 1/8 mile, then the car died, I didn't try to start it back up, after sitting all day they picked the car up on a tow dolly. They said they started the car back up, but it was running really bad so they shut it off. When removing the shreded serpantine belt, my husband found that some it between the timing belt and the pully that is lowest on the car. The timing was off three clicks/knotches. Once they got it back in time, the car was smoking out of the exhaust, smelled like oil had gotten into the exhaust. The chevy dealers that I have spoken with have stated that this car is known for this. Before getting the car totally back in time it was still off one click, my husband checked the compression in the valves. I don't know the numbers of the valves, but two did not have compression. He said that the two outside valves came up together and the two middle together and it was the first two valves that did not have compression, the two that don't come up at the same time. We are thinking of just replacing the entire cylinder head. he is thinking that possibly a valve is bent and oil is running down and getting in the exhaust. Any ideas of how possible it is that the head is still in working condition.

Well if the marks are lined up correctly and 2 cylinders have zero compression then unfortunately there is more than likely engine damage. This is an interference engine, meaning when a timing belt breaks or strips the valves can hit the pistons or each other causing damage. It will have to be torn down to assess the damage.
I have seen this scenario before but I wouldn't say it's common, we'll call this one a freak accident.
Just for future reference, when some type of engine problem happens, it best to just get it towed from where you're at. Probably the most common bad scenario is the overheat. Where the driver "just wanted to make it home", those 2 or 3 miles would've made the difference between a few hundred dollar repair bill and a few thousand dollar repair bill.
When somethings going wrong it can go from bad to worse very quickly, now if your safety is at risk then you have no choice, you have to drive it, anything else and you need to park it.
