I want to and this is my first 3.5L and am used to just cleaning 4 bangers all my life. Wasn't sure so I want to ask everyone here how they do it if they do it. Do you still cover the alternator with a plastic bag? What else should I cover? Spray lightly with a hose then spray a half degreaser/water mix, let it soak and scrub lightly with a soft brush all around the compartment then rinse and dry with a leaf blower?
