1997 Dodge Avenger Coolant/antifreeze leak

Hello for starter I would like to say thanks for all the helpfull advice u have given me so far. I have another? Regarding my antifreeze leaking. I have recently did a complete coolant flush and refill I also aired out all the air bubbles so I wouldn't have problems with the cooling system but now it's leaking I have narrowed it down to either a bad water pump, leaking inlet tube, or a bad water pump seal. When under the vehicle with it running inlet the car run till normal running temperatures while using a flashlight looking to see where it was leaking from I focused my attention on the crankshaft/pulley that's where it was leaking from but it didn't leak till the car reached the proper temperature. So my? Is would that be a sign of a bad water pump, bad water pump seal/gasket or my a bad water inlet tube seal? I really would need a good idea of what I should repair first hoping just one or the other. The car has 91910 I assume its about time for a new water pump anyways. P.S my temp gauge stays normal so it's not over heading at all but I have to keep antifreeze in the car to so just in case I do need to fill up.
