Alternator, battery, computer, etc. They might be "water resistant" but not water-proof

I would think you should let it cool all the way down to prevent warping.

XJGrason

well it was cold to the touch

dont spray it on the exhaust manifold if its been running for a bit.

I spray the crap out of mine esp. before anything major is worked on.

Same here. A surgeon could operate underneath my hood. Hot, cold, muddy or just dusty, it's all fair game when it comes to washing this horse. If this is all you have to worry about, I'd say you need a hobby or something.

XJGrason

well i just worry too much, i love my jeeps.

Last time I washed my engine it wouldn't start for 3 days lol so I don't wash it.... its nasty right now and buggin me but I can't have it down for 3 days again.

I have links to a hundred threads about issues following an engine wash but the good news is that I can't find a single one that actually resulted in any sort of permanent damage. The most common problem is a one to three day issue of not starting usually caused by water in the distributor or TPS that takes a while to dry out.

I don't recommend washing your engine but there are many who do with no problems, just be prepared for the possible consequences and only do it when your engine is cool. If you're not having any problems then don't worry about it and be careful of the sensitive electronics in the future.
