Syonyk's 7.3 Powerstroke Water Pump Suggestions

Ended up doing my water pump on Saturday somewhat unexpectedly, thanks to three snapped thermostat housing bolts...

Some suggestions from my experience that may or may not help other people:

- Rent the clutch fan tools. Seriously, rent the clutch fan tools. Also, despite all the warnings about "Right Handed Threads!!!!," don't think too hard. It's "normal threaded" - righty tighty, lefty loosy (when working from the front). Hold the pulley steady and perform standard operations on the clutch fan nut.

- When putting the fan clutch back on, the common instructions say, "Put the serpentine belt on first, then put the fan clutch back on." I would generally agree, but then say, "Loosen the serpentine belt before putting the fan on." If you do this, you can freely spin the water pump pulley to get the fan threaded. This is about 100x easier than trying to thread a 25lb fan and fan clutch onto the water pump when it's stationary. Just a suggestion.

- The new water pump o-rings (water-pump-shaped-rings?) are awesome. They have little nubs on the side of the o-ring to hold them into the groove on the water pump! It's awesome.

- After filling the system, you should probably burp the air out of the top of the water pump. Pull the heater hose off the top of the water pump (not all the way, but just to edge of the nipple) and let the air bubble out.

Anyway, hopefully this helps people who find themselves doing the water pump.

I like to stick a big piece of cardboard between the fan and radiator so I don't mess up the radiator with tools, fan/clutch, etc. Put anti-seize on those thermostat housing bolts!! Cheers!
