Changing spark plugs on 01 Ford Ranger?

To change the spark plugs on a 2001 Ford Ranger, first ensure the engine is cool and disconnect the negative battery terminal. Remove the ignition coil or spark plug wires from each spark plug, then use a spark plug socket and ratchet to carefully unscrew the old spark plugs. Before installing the new plugs, check the gap with a gauge and adjust if necessary, then screw them in hand-tight before using the ratchet to secure them. Finally, reconnect the ignition coil or wires and the negative battery terminal.
