AOS Procedure

[por356c]

Hello guys - I am going to risk being humiliated, but I am going to ask you all for some help anyway! My 02 Base is in storage for another 6 weeks so I can’t just go look at it. My issue is that in the Spring I am going to proactively replace my AOS before it fails and I am reading and studying. I am a modest DYI guy. I am a little spooked by this project. I am using Pelicans (Wayne Dempsey) instructions but he does not mention any other components that need to be removed before you can get access to the AOS from your engine compartment. I am suspicious of this and bet that there are some components that must be removed out of the way. But, to be certain, I want to ask: is there anything that must be removed to open access to the AOS from the top or is it sitting there just like in Wayne's Figure 2 picture, when you open the engine cover? Thanks fellas.
