How to change spark plugs... 2003 ES300

Hi!

You need New Spark Plugs, Spark Plug Wrench Socket and Wrench Extension (at least 2-3 inch) size 10 socket and/or size 12 socket.
First of all, please check where the spark plug cover is. Once you figure that out there will probably be size 10 or/and 12 bolts holding it down. Take that off and there you will see sensors connecting to each other and holding the spark plug in the cylinders. Unplug all the sensors and pull out the circular plugs holding the spark plugs down. Pull them out and make sure that you don't drop anything into the cylinderes. You can look down into them and see the spark plugs. Get your spark plug wrench, extension, and socket wrench and stick them down in and push so that the spark plug wrench grabs them. Then unscrew the plugs, pull them out and put the next ones in and tighten them down. Just connect all the sensors, and put the cover back on.
