Mazda Thermostat & Housing

The thermostat housing (along with other similar coolant ports) serves as an access point between the engine and other parts of the cooling system.  In more recent years, manufacturers have opted to make these housings out of plastic instead of metal to allow for easier manufacturing of complex designs while also keeping down costs.  However, the plastic housings can become brittle from heat and broken due to over tightening fastners or hoses upon installation.
