What are the signs of a failing water pump?

Another sign of a bad water pump is a loss of coolant. Typically consisting of a 50/50 mixture of distilled water and antifreeze, coolant is the “blood” of a car’s cooling system. When the coolant system works as it should, no coolant should escape due to its closed design. But a bad water pump may cause coolant to leak from its gaskets and seals.
