The thermostat housing is located in the engine between the engine and the radiator. When the engine cools off below the operating temperature, the thermostat housing is closed.
The common symptoms of a thermostat housing leak are a stuck thermostat valve, an illuminated low coolant warning light, and the P0128 or P0125 code.
If the thermostat housing is broken or leaking fluid, it needs to be replaced as soon as you can.
