How to align the timing belt of the je4d25q5a engine?

[SanHarmony]

There are timing alignment marks on the engine's timing gear, the front end of the crankshaft, and the flywheel. Rotate the engine crankshaft to position the first cylinder piston at the top dead center. Align the timing mark on the camshaft gear with the timing mark on the chain and secure it. Install the crankshaft drive sprocket and ensure that the timing mark on the chain aligns with the mark on the sprocket. Finally, make sure that the three timing marks on the timing chain correspond with the two timing marks on the camshaft sprocket and the one timing mark on the crankshaft sprocket.
