Can Coolant Leak Out of the Water Pump?

Yes, coolant can leak out of the water pump, and we will talk more about this below. A leaking water pump is just one sign that the pump has gone bad. Village Autoworks is going to list all of the signs of a faulty water pump in this blog post. If you drive a vehicle that has over 100,000 miles on it, this is the average lifespan of a water pump, so yours may be going bad sooner rather than later.

Coolant on the Garage Floor

An old water pump can spring a leak that releases coolant onto the garage floor. Depending on the size of the leak, you may end up with coolant spots or a coolant puddle. The water pump is located in the front of your engine, so you will see these spots on the floor toward the front of where your automobile is parked. It’s important to have any coolant leaks investigated as soon as possible and repaired.

Corrosion Around the Water Pump

Water pumps can also develop minor leaks that result in corrosion around the pump. You won’t realize that you have a coolant leak because there won’t be any indication of one on your garage floor. Rather, the coolant will leak out of the pump and pool around it. When this happens, the pump ends up getting corroded. In severe cases, you may also see tiny holes or pits in the pump that indicate rust damage.

Unhealthy Coolant Circulation

If the water pump is malfunctioning, it may not be circulating the coolant through the engine as well as it should be. This is much like someone who has heart problems that result in blood circulation problems. The coolant needs to circulate through the engine once the thermostat releases it. If the water pump is dead or dying, you may end up with unhealthy coolant circulation in the engine.

Whining or Squealing Noises

One thing that can affect the coolant circulation is the accessory belt. The water pump is attached to this belt and this is the belt that powers it. If you hear whining or squealing noises, particularly when you first start your automobile, your accessory belt may be too loose. This can cause problems with the water pump.

Constant and Fast Overheating

Finally, all of these things will make your engine overheat quickly after you have started your automobile. The overheating engine is an indication that it is not getting the coolant it needs to keep the temperature below 220 degrees Fahrenheit. This could be due to a faulty water pump.
