Play in the water pump pulley is a sign the pump is going out. Relaese the tension on the auxiliary belt and then chaeck the pulley for wobble. I replaced the belt and the pump failed promptly after that.
Its important to catch the pump before it fails because when it does, the plastic impeller tends to grenade, which can send little bits of plastic into the tiny coollant passages in the head which can cause blockages and lead to cracked heads or blown head gaskets.
Many people treat the pump as a wear item and replace it periodically, 30-50k miles to avoid problems.
