Cleaning engine. What to cover in a 3rd Gen?
I'm going to be using a few engine degreaser/cleaner products that I'll rinse out with water. What should I cover, and is masking tape ok for these purposes?

I did this a few years back and placed a plastic bag (as best I could) over the alternator and another on the battery. Two things that water do not play nice with.
That's all I did and turned out ok for me.

I used a pressure washer with a fan sprayer over pretty much everything. Don't point it right at the firewall grommets, generally avoid the alternator - and otherwise just go for it... (assuming you don't have an open element air filter or something like that)
Others may disagree though, of course.

I just deep cleaned my engine bay and detailed it. I try to get everything as clean as I can without water first. Then spray cleaner down strategically (ie. avoid electrical, battery, etc.) and let it soak for a bit. I then hosed everything off (again strategically) and wiped down everything as best I could.
Results:
Products used (and water of course):
It came out very clean, looks even better in person. I do this on all our vehicles and never bag or cover anything, just careful with where I am spraying and have never had a problem on any vehicle. Don't forget to clean the underside of the hood too.

As stupid as this sounds, there should be a "how to" or sticky on cleaning the engine bay and what products people use for each component.
Personally I would pull the battery and bag the alt, service port, fusebox, any extra relays/ballasts, etc just to be safe - but I also like to make extra work for myself
Which reminds me, need to degrease and clean off my skid plates.

I usually spray simple green then rinse it with hose. Try and avoid electrical things. Let it air dry. Then use a compressor to blow out he rest out

I haven't cleaned mine sine I got the truck basically a few years ago. I want to clean it, but as soon as it gets out into the dust/dirt again it's dirty so it's hard to make it a priority. I try to keep up with cleaning the outside more often since that's what you see.

This is after about 6-9 months of driving with some offroading:
Its a little more dusty now (another 9 months later), but as long as you stay out of deep mud, it stays pretty clean... as long as you keep leaks under control and don't use any products that attract dirt.

Battery and alternator don't care about spray from the water. The biggest thing would be to not use a pressure washer as it can rip sensor wires off or force water down into spark plug holes and cause misfires.
Use nothing more than a garden hose and some degreaser, purple power, simple green, etc and a brush or two.
I used to detail vehicles for a dealership and back when cars had distributors, they could get water in them and cause poor performance. Now, as long as the force from a garden hose isn't too great, there's little chance of blowing off a vacuum line or sensor connector, but with a pressure washer, there's a much greater chance of breaking something.

I just use Simple Green and a waterhose with adjustable sprayer. Bag off the obvious electrical.
I park out in the sun so it'll dry faster before 1st start up, and I also used some electrical contact cleaner spray on the obvious plugs to force any sneaky water droplets out.

Haha, I was going to mention the distributor, been there done that. But I figure some of the people on here wouldn't really be able to relate
