It's pretty much exactly how it sounds. It's a housing usually made of some type of metal (it's sometimes plastic) that holds the thermostat between the engine and the radiator. Generally speaking, if you follow the upper radiator hose to the engine, it meets the thermostat housing. (There are a few exceptions to that rule, though)

It's the piece that covers the coolant thermostat and typically has two or three bolts that hold it in place. Some thermostat housings hold vacuum switches and or coolant temperature sensors and this adds to the cost if it cracks and has to be replaced.
The thermostat controls the flow of coolant (water/antifreeze) into the radiator from the engine.
Good Luck!

It's a removable cast iron, aluminum or plastic housing that usually connects the top radiator hose to the intake manifold or block. Inside the housing is where the thermostat is placed. the heat sensitive coil spring and copper biscuit on the thermostat always points toward the water jacket.
