The cover just pops off. Near each corner has a pressure point. Just lift on the corner and it will pop up. It pops back on just as easy.
I've had my cover off just to see what the engine looks like. It's really quite ugly. Nothing but tubes, hoses & lines haphazardly placed. Reminds me of a dieing patient in the hospital hooked up to life-support.
In the good old days, we could clean up the engine bay and show off a beautiful engine. But, watching a 500 pound woman do a strip tease is not a beautiful site. Please, put your clothes back on, before I go blind.
