How to align the timing belt of Hyundai Sonata?

[McJustin]

Sonata timing belt alignment method is as follows: 1. Rotate the engine crankshaft to position the No. 1 cylinder piston at top dead center and fix it; 2. Align the timing mark on the camshaft gear with the timing mark on the chain and fix it; 3. Install the crankshaft drive sprocket and ensure the timing marks on the chain and sprocket are in the same position; 4. Finally, ensure that the three timing marks on the timing chain correspond one-to-one with the two timing marks on the camshaft sprocket and one timing mark on the crankshaft sprocket. Additional information: 1. When the engine is running, the piston stroke (up and down movement), valve opening and closing (timing), and ignition sequence (timing) must always remain synchronized under the action of the timing connection. 2. Timing refers to the process where the engine's timing mechanism ensures that each cylinder precisely achieves: the piston reaching top dead center, the valve closing, and the spark plug firing at exactly the right moment.
