Try to put the question in the right section to begin with and when you come back to view any answers navigate to that specific section.
Use the search feature on this page at the top right to search for any key words in your original question like thermostat housing.
It is possible that nobody has taken the trouble to respond because they either don't know or can't understand the question usually because the original post failed to mention the particular make or model involved - somewhat like this question in a way.
