2008 Aveo Timing Belt

Hello all, I figured this was the best place to come for genuine advice 🤞

I bought a 2008 Aveo the other night. Seller told me the fan belt tensioner needed to be replaced but wasnt a big issue.
Turns out on my way home, the timing belt went.
I was in first gear, taking off and that was it. I dont think it would have done much damage but I don't know much about cars.

Has anyone experienced this?

Can I just put the belt back on or do I need a mechanic to do it? I cant imagine the pins or clogs moved an awful lot but a friend says if I put the belt on wrong it could ruin the engine?

Would I be as well off trying it myself, getting a mechanic to try and fix it or search for a new engine?

I'm on a very tight budget so need to pick the best option and go with it.

Thanks in advance.

The engines are interference engines, so there is a good chance that the valves made contact with the pistons.
Did the belt completely break or jump a tooth?
The belt can be done on your own, but you need to check to make sure none of the valves are damaged before going any further. Otherwise you would be wasting your time.
If you can get ahold of an inspection camera, you can pull the spark plugs and try to scope things from there. Another option which will make things easier to see, but requires a bit more work, is to pull the exhaust manifold off and inspect each cylinder from there.
Good luck!
