In the engine system, there is an important part named thermostat housing. The thermostat housing serves as the coolant outlet and the location of it are on either the cylinder block or intake manifold. The main function of the thermostat housing is to contain the engine thermostat and offer a coolant outlet to the radiator. Also, the thermostat housing serves as an air bleed point for the cooling system. However, the thermostat housing is just like all other parts in the BMW car can be worn one day. It is common for thermostat housing to be replaced because of leakage, and another reason for replacement is if pitting develops on the gasket surface, which may be noticed when the housing is removed to service the thermostat.
