i am going to clean the engine bay this afternoon but i heard that some parts of the engine bay need to be covered and protected from the water or the car wont start. What do i have to do to prepare it to be cleaned, i will just be using plain car wash soap and a sponge to clean it.

 

i also heard u have to cover up the opti, what is that????

oh by the car is a 98 ss

 

You don' thave an opti, only 93-97 F-bodies have the opti. You don't really have to worry about anything, just make sure all your connectors stay intacked while your spraying everything down.
