Thermostat housing, an engine system, and a method for operating a thermostat housing assembly

An engine system comprising:

• an engine;
• a downstream component in fluid providing communication with the engine;
• a radiator assembly positioned between the engine and the downstream component, the radiator assembly in fluid providing communication with the downstream component;
• a radiator bypass positioned between the engine and the downstream component, the radiator bypass in fluid providing communication with the downstream component in parallel to the radiator assembly;
• and
• a thermostat housing assembly comprising:
• a thermostat housing defining:
• a cavity in fluid receiving communication from the engine and in selective fluid providing communication to the radiator assembly and the radiator bypass;
• a first aperture in selective fluid providing communication from the cavity to the radiator bypass;
• and
• a second aperture in fluid providing communication from the cavity to the radiator bypass;
• and
• a valve assembly adjustable between a first configuration that selectively prevents fluid providing communication from the cavity to the radiator assembly and a second configuration that selectively prevents fluid providing communication from the cavity to the radiator bypass through the first aperture, wherein the cavity is in fluid providing communication with the radiator bypass through the second aperture when the valve assembly is in the second configuration.

A method for operating a thermostat housing assembly, the method comprising:

• operating a valve assembly in a first configuration, selectively preventing fluid providing communication from a cavity of the thermostat housing assembly to a radiator assembly;
• adjusting the valve assembly from the first configuration to a second configuration;
• and
• operating the valve assembly in the second configuration, selectively preventing fluid providing communication from the cavity to a radiator bypass through a first aperture of the thermostat housing assembly, and permitting fluid providing communication from the cavity to the radiator bypass through a second aperture of the thermostat housing assembly.
