Water Pump - Coolant Weepage

Don't Cry Over
Weeping Water Pumps

A little coolant leakage from the water pump weep hole doesn't necessarily mean the pump seal is shot. The weep hole is just doing its job of keeping the coolant away from the water pump bearing. As long as there's no measurable coolant loss, the pump is still good.
