Carefull with the cleaners you use. Some can leave the aluminum with white corrosion "dust." Be carefull to get all the water out of the bolt recesses in the plenum. They are excellent "buckets" to hold water, and will corrode the bolts in there. I had to undo my bolts one at a time, work at them with some Naval Jelly and a wire brush, then spray paint them flat black. Someday I may go back and install SS Allen head bolts.
Another detailing trick I'll share - spray down the engine with a nice foaming tire dressing. Best to do with a nice warm engine. When you come back from your drive to dry out the engine compartment, lift the hood, hose everything down with the tire cleaner/dressing, and close the hood. Next day, open the hood, and marvel at how wonderful your engine bay came out!
I haven't had any problem with the alternator, but I don't clean my engine on a weekly basis, either. 2-3 times a year at most. If it does need replacing, I'll go to Autozone for a replacement, and have a lifetime warrenty on the replacement.
