With all these stupid sensors on and around the engine it’s hard for me to clean the engine. Anyone have a good solution to cleaning the engine bay ?

 

I've always used a good degreaser, usually Super Clean or similar, then hit it with water. Never covered anything. I do mine at the car wash and use the pressure washer. Just don't soak anything for longer than a second at a time and you'll be fine. Dry after, or shut the hood and let the heat dry it. Apply your favorite dressing. done.

 

Remove battery, cover alternator and keep water out of the cop/plug wells. Honestly....I'd just use some degreaser and a bunch of damp/dry towels

 

It's an engine, not a kitchen table.

 

While I agree for the most part, some people just enjoy cleaning what they own.

 

I spray mine with simple green. Let soak for 10 minutes. Rinse with low-pressure water spray, and immediately dry off with my electric leaf blower, ensuring that I get all the electrical and nooks and crannies. Living dangerously, am I.

 

Awesome from the dollar store

 

Agreed. Hidden gem, and good cleaning bang for a buck.

 

One might could say.....that it's awesome

 

I've been in the car business all my life and am now retired. If you go to the dealers used car reconditioning shop, watch how they clean an engine bay, you'll get an idea of what an engine can withstand.

In my experience, they blast the daylights out of it with hot water or steam.
Yeah, I know, it's not their car (truck), but whatever they do, there seems to be no ill effect. Not what I would do, but that's what I've observed.

When I do mine, I spray some foaming engine cleaner around, being careful to not saturate the electronics. I do this at the quarter car wash with a warm engine.
I also spray the underside of the hood edges, being careful to not get too much cleaner on the fiberglass pad.

Then, after the cleaner has had time to soak, I get after all the crud with the high pressure wand, again, being careful to not saturate any electronics. Common sense goes a long way here. I'm careful to not direct high pressure spray into my alternator, coils, and fuse panel. You can damage your under hood pad with the high pressure, so be careful there too. As soon as I'm done, I start the engine and let it run until I'm confident that everything has dried out. It's 12 miles from the car wash to my house, so that's usually enough to dry everything.

Simple Green does a good job if you use an old wash mitt and can rub into the nooks and crannies. Probably less chance of an issue that way.

Good Luck, L.M.
