Claim 7:
8. A pre-packaged water pump assembly comprising:
a package comprising a water pump assembly;
the water pump assembly further comprising:
a housing including an exterior surface and one or more openings that extend through the exterior surface of the housing;
one or more retainer structures positioned on the exterior surface of the housing, the one or more retainer structures comprising one or more apertures, each of the apertures in the one or more retainer structures corresponding to one or more openings of the housing;
a plurality of pre-installed fasteners enabling connection of the housing to an engine assembly via one or more of the openings that extend through the exterior surface of the housing, the plurality of pre-installed fasteners inserted into one or more of the retainer structures via one or more of the corresponding apertures in the retainer structure prior to connection of the housing to the engine assembly; and
a thermostat comprising a temperature-controlled valve assembly, the temperature-controlled valve assembly at least including:
a primary valve;
a bypass valve;
a charge cylinder; and
a spring surrounding the charge cylinder; and

wherein:
the thermostat is configured to regulate a flow of coolant to an engine assembly;
the primary valve, the bypass valve, the charge cylinder, and the spring are included within the housing of the water pump assembly;
the primary valve is configured to transition between an open position and a closed position within the housing of the water pump assembly;
when the primary valve is arranged in the closed position, a first passageway inside the housing directs the flow of the coolant to the engine assembly; and
when the primary valve is arranged in the open position, a second passageway inside the housing directs the flow of the coolant through a radiator assembly.
