To change the spark plugs on a 2001 Lexus GS300, first ensure the engine is cool and disconnect the negative battery terminal. Remove the engine cover and spark plug wire harness to access the spark plugs. Use a socket wrench to carefully unscrew and remove the old spark plugs, then install the new ones, ensuring they are properly gapped. Finally, reconnect the spark plug wires and battery terminal, and replace the engine cover.
The 2001 Toyota Sienna spark plug gap is .023. Most spark plugs will be pre-gapped by the manufacture of the spark plug.
