How Does an Electric Water Pump Function?

There are two general classes of water pumps: electric powered and belt powered. Electric water pumps utilize the vehicle's electrical current to drive the water pump motor. When the power is applied via an electric current, the resulting motion of the interior pump assembly pulls coolant through the inlet valve and pushes coolant out. Since an electric water pump functions on electricity, you may need to replace the fuses for the circuit as required by the vehicle manufacturer. If the electric water pumps fail to engage, check for power at the connection before removing any additional parts.
