95 S6 Coolant leak

[Peter Golledge]

Listers,

 

Looks like my wife's 95 S6 detected that new node in our RAIC (Redundant
Array of Inexpensive Cars) and decided to leak coolant.

 

It is a slow leak dripping down from the block right behind the Harmonic
balancer.  I've felt only the plumbing above (hose under intake, thermostat
cap + hose) and can't find any sign.  I've got to believe the only other
source is the water pump.   I've got a TB replacement due in 4K miles so if
I have to do the pump I know the drill.. Any other thoughts?
