Take lots of pictures, from every angle. Tag every vacuum line and harness connection so you know where everything goes. Drink a beer. Put the bolts and nuts you remove back where they go if you can, and if you can't put them in ziploc bags with a tag telling you where they go. Pop the crank pulley nut free before you take the motor off the transmission. If your AC still works, take the pump off the motor without cracking the hoses and leave it in the engine bay. Drink another beer. If you don't have a parts cleaner, save yourself several hours and take the throttle body and intake plenum down to a shop and see if you can give them a couple bucks to clean them for you. Take the TPS off first and don't let anything contaminate it, those things aren't cheap. Drink more beer. Check all the studs in the head on the intake and exhaust side, and if any are wobbly or loose now is a great time to helicoil them, instead of after everything is back in the truck. Take your time and be methodical, and drink lots of beers.
