Washing Engine Bay

This had made for some interesting reading. I have always used a pressure washer (kept the head at least 2' away) on the hood and around the edges of the engine bay. Also sprayed lightly over the engine, but I did cover the alternator. After spraying on soap with a spray bottle and agitating with brushes I would rinse it off and then blow dry with an air cannon. Have never had an issue. But this is my first auto with a splash guard so not sure if things are more prone to water infiltration.

This video shows how I usually do my engine bays. I was curious to know if I had to drop the engine splash guard which I think I would.


You guys are making me a little nervous although I have never had a problem doing one before.

I am really surprised with how many are really worried about causing electrical problems. I have washed the engine bay of most of my vehicles over the years (now 65) and only had 1 minor problem, but that was on a used car that was really dirty and I did get pretty aggressive with the power wand at the car wash. I guess if I am going to wash the bay I have to drop at least half of the splash shield on the bottom. Or try and have the car on a slope.
