I am about to install Super Chip and Airaid system on my truck, but want to powerwash the engine and compartment first. Anything I should look out for aside from the normal electrical componets, etc.
Any help would be appreciated.

 

To add to the spark plug warning, you may want to stay away from the alternator and the fuse/distribution box; they're both fairly waterproof but just don't hold the power sprayer on them. Also don't hold the high pressure water on the engine seals, they get brittle on the outside and the water will knock chunks off of them, weakening the seal.

One more thing, make sure the engine is cold so you don't crack the engine block.

stay away from the spark plugs w/that water

 

Actually, I've always felt it best to leave the engine running when I clean it. I agree with the comments of others saying to not use high pressure directly on the distribution box, etc., but I've always done the alternator too, and haven't had any problems, but I don't use the highest pressure, and I don't do anything more than necessary to get it clean, no extra. Whatever you do, make sure not to spray the spark plug area unless you dry out the well that the plugs reside in, as that what causes a lot of plug wire boots to fail, the accumulated moisture.

I use the typical 110-volt pressure sprayer, so it doesn't really put out a lot of water volume, but produces enough pressure toget the job done in a very tightly focused area, so it's easy to make sure some things don't get a major blast.
