Anyone tried steam cleaning engine bay?

I never used a hose nor pressure washer. Not my method, regardless being save or not.


It's not needed, imo, if you don't do Paris-Dakar with the car, there is no reason the engine bay gets dirty in the first place.

That is the worst advice here yet.



The 1989 technical bulletin doesn't apply here. These cars can take high (wide fan) pressure just fine. Use your head when it comes to spraying areas of concern (for example, if your coil cover leaks, don't fill spark plug holes full of water washing your engine...) Simple Green is a terrific product. Purple Power, even "aluminum safe" I learned the hard way to not trust (use caution if you do use it). You must dry after your wash to avoid water spots, especially in areas with hard water. Towel dry or use a leaf blower.



Super heated high pressure hard water leaves horrendous water spots almost immediately. Heat does not eliminate spotting at all (from the source or hot engine bay).



(E46 is just as applicable here as the electrical connectors are all roughly the same)

proof is in the pudding right there! damn!
