My first feeling was that the water pump was going bad, but I wanted suggestions from others - I seem to remember that it was dripping in a similar pattern last time I had the pump replaced. I've already taken a look at the hoses, and none of them seem to have the white crystals that I'd expect to see from a leaky hose.

Is a water pump replacement a DIY-able job? I've sucessfully tackled the replacement of the fan bearing and clutch before without too much difficulty. Going through the repair CDs I know I'm looking at 20-2100, but do I have to do 13-3200 and 20-3120 (belt tensioner removal and viscous fan clutch removal) also?

Are there any special tools I need? Some of those allen bolts look tricky to get to.
