How do you set timing on 2004 aveo?

To set the timing on a 2004 Chevy Aveo, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Remove the timing belt cover and align the timing marks on the crankshaft and camshaft gears. If necessary, adjust the timing belt tensioner, and then recheck the alignment of the timing marks before reassembling. Finally, start the engine to ensure it runs smoothly.
