Sounds like water pump needs replacing The main pulley is near the top of the engine. The water pump is toward the front of the engine. It is possible that water appears to be leaking from this pulley, but there is a manifold gasket right above it. Double check to find exactly where the water is exiting the engine block. My first hunch is a leaking gasket.
Leaking? Pulley loose? Noisy? No coolant circulation?
There should be a seep hole in the front of the pump either under or behind the pulley. Usually if the pump is done, there will be coolant leaking from there. If you are rebuilding the motor, it is cheap insurance just to replace the pump.
There is a weep hole at the bottom just under the pulley where there will be a stain of coolant if it is leaking. Or unhook the belt and check the play of the shaft of the water pump.
The water pump on a 97 Nissan Sentra is behind the timing belt. To replace it you will need to drain the coolant, remove the cylinder head, loosen pulley bolts, drive belts, and water pump pulley. Next, remove coolant hoses, water pump bolts, and finally the old water pump. Reverse directions to replace with new pump.
Check the hose that goes into your water pump but most likely it is a bad water pump dripping from the weep hole. I would replace the water pump if you can trace the water from that area
water pump .(gasket,intake,hose)
The coolant will run out of the timing cover from behind the crank pulley.

loosen the tension pulley bolt which is in the middle of the pulley, use a wrench, little work space is provided, just a little bit, then lossen the bolt that is behind the pulley, tho relive tension in the belt. take off the belt, and put on new one and tighten the bolt behind the pulley till belt is tight, then retighten the pulley bolt.
