In some embodiments, a solenoid-actuated pump includes a first pumping chamber and a second pumping chamber, where the first pumping chamber delivers fluid from the pump to portions of a vehicle to facilitate the operation of the vehicle. The second (or “parasitic”) pumping chamber implements a forced convection cooling method, which utilizes parasitic pumping loss to produce a flow within and/or around the solenoid coil to cool the coil and/or maintain the temperature of the coil during operation. In this manner, the second pumping chamber produces a flow that reduces thermally-related increases in electrical resistance of the solenoid coil of the solenoid-actuated pump.
