A faulty water pump (WATER PIPE LEAKING) in a vehicle or other systems can lead to several signs and symptoms. Here are the most common indicators that a water pump may be malfunctioning:

1. Overheating Engine:

   • One of the most common signs of a faulty water pump is an overheating engine. The water pump circulates coolant throughout the engine to prevent it from overheating. If it fails, the engine may quickly overheat, causing potential damage.

2. Coolant Leaks:

   • If the water pump is leaking coolant, you may notice puddles of coolant underneath your vehicle or around the water pump area. This is often caused by a worn-out gasket or seal.

3. Whining or Grinding Noise:

   • A worn-out water pump bearing can cause a whining, grinding, or squealing noise coming from the pump area. If you hear unusual noises when the engine is running, the water pump may be to blame
