How do you change the spark plugs in the 2002 Toyota 4Runner? Do you 
have steps on what and how to remove in order to access the plugs? 
Thanks.
Answer: 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.
