How do you replace timing chain on 1998 Nissan 200sx with 1.6 liter engine?

To replace the timing chain on a 1998 Nissan 200SX with a 1.6-liter engine, first, disconnect the battery and remove the necessary components, including the engine covers and the oil pan, to access the timing chain. Align the timing marks on the crankshaft and camshaft to ensure proper timing, then remove the old timing chain and guide rails. Install the new timing chain, ensuring it is properly tensioned and aligned with the timing marks, then reassemble the engine components in the reverse order. Finally, fill the engine with oil, reconnect the battery, and start the engine to check for proper operation.
