2002 Toyota 4Runner Question: Changing Spark Plugs
Answer #1Andy Y January 21, 2009, 10:36Master
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.
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.
4crawler's site has some info on service manuals too.
