The inside of my engine bay is a little dirty and just real dusty! I have seen people just spray them out with a hose... is that ok? And what about spraying it down with some purple power or something?
spray cool engine down with simple green let soak in then pressure wash off then air-hose it as dry as you can so water doesnt sit in bays and connectors dont short. Also stay away from the alternator as much as possible. it can get wet but dont drench it
Wellllll... I soak the shit out of mine the only thing i'm careful around is the connectors and the ecm,pcm, and the fuel module by the fuel filter... the rest is fair game, not a lick of trouble after 6 years, this is with pressure washers.
Spray nine works wonders on diesel and oil to btw.
I have used solvent-[mineral spirits] for many-many years. It really cuts the grease/oil and drys fast. Don't have to worry about shorting connectors or electronics. I do it in the garage, and use cardboard to catch the debris.
