How do you set timing on a 2002 ford explorer 4.0 liter?

To set the timing on a 2002 Ford Explorer with a 4.0-liter engine, first, ensure the vehicle is off and the ignition key is removed. Locate the timing marks on the crankshaft pulley and the timing cover, then align the marks to the specified timing degree, usually around 10 degrees BTDC (Before Top Dead Center) for this engine. If you’re using a timing light, connect it to the battery and the number one spark plug wire, then start the engine and adjust the distributor until the timing light indicates the correct timing mark alignment. Finally, tighten the distributor hold-down bolt and recheck the timing to ensure it remains aligned.
