prep for engine bay powerwash

[stayalert]

Next weekend I hope to push my car of the garage and powerwash the engine & engine bay. In preparation I have

- removed the radiator and oil cooler (for more room and I'm going to re-tap the lower oil cooler fitting anyway)

- removed the air cleaner housing
- removed the alternator
- removed the fan
- protected the ac "radiator thing"
- removed the battery

I plan on wrapping any accessable electrical fittings and capping/sealing any open hoses or tubing, or fittings (valve cover breather for example)

Are there other precautions I should take or be familiar with?

looking forward to a fresh look at where all the leaks are coming from.....
