The thermostat housing is a square 'plastic' block that is bolted to the cylinder head. On the side where the block contracts the cylinder head, around the coolant hole, there's a groove machined into the 'plastic' that contains an O-ring, that seals that surface.

Hello. The thermostat gasket is most likely what is causing the leak. The gaskets overtime become hard and lose the ability to seal the coolant passing by the thermostat. The replacement of the thermostat and gasket is the most prevalent fix. It could also be a crack in the plastic structure of the thermostat housing which is causing the leak. I suggest having the cooling system pressure tested by a well trained technician. Pressure testing the system will expose any coolant leaks. A properly trained technician would be able to inspect the coolant leak and make the necessary repairs to have your vehicle running smoothly again.

  • The rings are bad or you over filled with oil. White steam, on the other hand, means that water is getting into the combustion chamber. That can be caused by a cracked engine block, a cracked head, or a leaking head gasket. Replace the thermostat housing, stop that leak and see what happens next!
