In a car, the heart of the cooling system is the water pump. Its purpose is to circulate engine coolant throughout the whole system, beginning with the radiator, and then to the engine and back again. The water pump is what allows your air conditioner to work when it is hot out.

The water pump gets its power from the car’s engine. It will either use a gear and chain system or belt and pulley system. The water pump generates power that then travels to a shaft with an impeller.

Then, the impeller circulates the coolant through the entire vehicle. The impeller is similar to a propeller that causes a boat to move.

The impeller and the shaft spin on a bearing that is sealed. It is essential to check this part of the water pump because it has a tendency to wear out easily. Make sure to look for leaking coolant and a strange noise. Also, know that a wet engine is a sign that your water pump should be replaced.

If you see any of these signs, make sure you replace your water pump. In addition, it is a good idea to sign up for a roadside assistance program in case you find yourself in an emergency situation. After all, you never know when your vehicle will fail.
