Don't worry about the water pump... it's a $60 dollar item and takes 20 min. to change (Slip the belt off, remove 2 screws, pull out old pump, put in new pump, replace two bolts, put the belt back over the pump pully). Mine started weeping at cold start up at 103K, just a few drops. Replaced it this weekend. Strangley... my original pump didn't have the 'weep hole' that the manual says to inspect and keep clean... new pump does have the hole.
