I see the thermostat housing (attached photo) at the end of the top radiator hose. Before I take it apart, my past experience with other cars has been that the themrostat sits inside the housing and is a simple take out old/put in new process but I can't yet see nuts to take apart the housing. When I detach from the hose clamps will this become evident or am I to replace the entire housing?? I am assuming there will be some coolant loss when removing from the hoses......do I just add replacement coolant after reassembling or does the system require flushing?
Thank you
