They are right on top of the engine covered by 4 rubber boots. They are easily changed with the right tools. First, obtain a Hayne's manual for about $20.

Read the manual verbatim and you can do it in about 1 hour tops seeing this is your first time. I can do it in about 8 minutes but I've been doing it for about 20 years.
