Q: Diagnose bad water pump

asked by on

How do I know if water pump is going bad?

My car has 250 miles.

Generally, when a water pump is going bad, you may hear a bit of a whining sound combined with the pump leaking. The most common place for the water pump to leak from is the pulley shaft seal which is in the front of the pump where the shaft comes out of the pump housing. When the pump is leaking, it will typically cause the engine to overheat as well. I would recommend having an expert from YourMechanic come to your location to diagnose and replace your water pump.
