What is the proper alignment of the timing marks on a 1997 Chevrolet 2.2 when you are replacing the timing belt?

When replacing the timing belt on a 1997 Chevrolet 2.2, align the timing marks on the crankshaft and camshaft gears. The crankshaft mark should be aligned with the 0° mark on the timing cover while the camshaft timing mark should be pointing straight up, aligning with the mark on the cylinder head. Ensure that the tensioner is properly adjusted and the belt is taut before finalizing the installation. Always double-check the alignment before reassembling other components.
