Hello everyone, I am new to the site. You guys are a wealth of knowledge so I have a quick question for you. We have my wife's car in the shop and they are telling me the "thermostat tube and connector" are leaking and need replaced. I can not find any information on this part so I thought I would ask you guys. All the would tell me is that it goes to from the block to the thermostat housing and it is 175 for parts and 325 for labor. Anybody have any input on what part they are talking about? Thanks in advance for your help. Oh yeah, it's on a 2005 Lincoln LS with the 3.9L.
