How do you change plugs in 01 suburban?

To change the spark plugs in a 2001 Chevrolet Suburban, first, ensure the engine is cool and disconnect the battery. Remove the ignition coil or plug wires from each spark plug, then use a socket wrench to carefully unscrew the old plugs. Before installing the new plugs, check the gap and apply a bit of anti-seize compound to the threads. Finally, install the new plugs, reconnect the ignition components, and reconnect the battery.
