I am currently working on my wife's 93 Bronco with a 351. It has a water leak. The part that is leaking is a two inch tall hex piece that the coolant temp sensor screws into. Also the throttle body has a small rubber hose running to it. I have searched a number of sources to try to find the proper teminology for it without success. Also if you know what this is, do you know if there is anything special about removing it. It has a foot long metal tube coming out the side that the heater core hose attaches to. There doesn't appear to be any way to unscrew it without cutting the tbe off. Any help will be appreciated.
