What is the lifespan of the EA111 timing chain?

[KendraAnn]

The lifespan of the EA111 timing chain is: it can reach 150,000 to 200,000 kilometers. Its main functions are: 1. Driving the engine's valve train to ensure the intake and exhaust valves open or close at the appropriate time; 2. Ensuring the engine cylinders can properly intake and exhaust. The method for aligning the timing chain is: 1. Rotate the engine crankshaft to position the first cylinder piston at top dead center and secure it; 2. Align the timing mark on the camshaft gear with the timing mark on the chain and secure it; 3. Install the crankshaft drive sprocket and ensure the timing mark on the chain aligns with the mark on the sprocket; 4. Ensure the three timing marks on the timing chain correspond with the two timing marks on the camshaft sprocket and one timing mark on the crankshaft sprocket.
