2002 Toyota 4Runner Question: Changing Spark Plugs
The ignition coils cover the spark plugs on one side of the engine and plugs wires are on the other side. When I work on engines I am not familiar with, I will replace one spark plug and wire at a time. This way I do not have to worry about getting the firing order wrong. Autozone's website has free repair guides and has instructions on how to replace the plugs for your 4runner. I personally like to put a small dab of anti-seize on the new spark plug threads when installing new plugs. http://www.autozone.com/shopping/repairGuide.htm If you plan on working on your 4Runner I do suggest finding a service manual. The 4runner and Tacoma have a large following in the off road community and resources online are also widely available. http://www.4crawler.com/4x4/FSM.shtml 4crawler's site has some info on service manuals too. - Andy Y
