One sign of a faulty water pump is coolant leakage

Any signs of a broken water pump you may be experiencing could be corrosion. Polluted or improperly mixed coolant can lead to corrosion on the impeller inside the pump. The belt slipping on the pulley could be a problem if there is outside corrosion. In other cases, the only indication that the water pump is broken may be its outward look, such as evident rust or buildup.

As soon as you find an issue with your water pump, fix it. Delaying repairs often results in more costly and inconvenient outcomes. Most likely, you’ll require coolant and gaskets.
