Coolant Leak

[Derek Pulvino]

....and I've got a new afterun pump, replaced after the impellor housing 
self destructed about two years ago.

Not to be a jerk but, let me emphasize that I've found the coolant leak to 
be coming from the front of the engine via the trackmarks of coolant drips, 
and where it's dripping from.  So my question on "any suggestions" was more 
toward does anybody know of any other potential leak sources on the front 
(timing belt side) of the engine that I hadn't already named, and for the 
ones named, has anyone come across an easier than pulling apart the front 
end trouble shooting method.
