The piece in back of the thermostat housing is the bypass housing, and a plug blew out of mine. My other failure was the plastic t in the upper radiator hose. One of the hoses is available aftermarket and is much cheaper than oem. It's about $600 in plastic at retail from the dealer.The outlet pipe (it's the back half of the thermostat housing), and the plastic parts in the middle of the two radiator hoses.
