Your vehicle’s water pump is basically the heart of the cooling system in your car.  It performs the task of circulating engine coolant throughout the system going from the radiator, then to the engine, and back again.  This allows you to enjoy air conditioning in hot temperatures.

Your engine gives the water pump the energy that it needs to work correctly.  It either operates through a belt and pulley, or a gear and chain.  The power that is generated by the pump goes to a shaft with an impeller.

The impeller spins, circulating the coolant all around your vehicle.  The impeller is similar to a propeller that moves a boat.

The shaft and impeller spin on a bearing that is sealed.  It is important to check this because this part of the water pump will wear out.  So, look for leaking coolant or a strange noise.  Also, an engine that is wet is a sign that your water pump needs replacing.

If any of these signs are apparent, replace your water pump.  In addition, to these signs, your water pump will either be working correctly or not.  It is necessary to purchase an auto warranty for repairs such as this that are unforeseen.  After all, you want to protect your wallet.
