I wash the engine bay in my Camaro frequently and I don't cover anything, light fan with the hose etc, etc. How about a 2016 Ram 2500 Turbo Diesel? Long road trip and my engine is filthy. I don't feel as comfy doing the same as my Camaro. Any suggestions, experiences, or just do the same?
I've searched YouTube and I've found from "don't do it" to "pressure washer crazy"......Using pressure washer I think is "Crazy".
