Coolant leak from the weep hole
Coolant dripping from the pump body means the seal has failed. Replace the pump before the engine runs low and overheats.
Overheating
A worn impeller moves less coolant. If the engine runs hot with a good thermostat and radiator, check the pump.
Bearing noise or play
A rumble or play at the pulley means the bearing is worn and the seal will follow.
Service at the same time
Change the thermostat, belts and coolant while the pump is off.
