I have a 1985 Mercury Lynx (Ford Escort) Diesel 4 cylinder. The device shown in the pictures -- below the starter -- has a hose connecting it to the radiator. There is another hose that is connected to nothing, and it has a hole in it. A small drain hose/switch is on the bottom of it was ripped off, and that is leaking oil really bad to the point where the car cannot be a daily driver.
I do not know what this does or what it is called, nor do any of the mechanics around here. Before anyone works on this, I want to know exactly what this component does so I can be sure not to get ripped off when I take it into the mechanic.
I unplugged it -- it has an electrical plug -- and started the car, and it started smoking out of the tailpipe. This car never smokes. What does this thing do? If you can provide a hyperlink to the part, that would be awesome!
Please let me know if you need more information, and I will edit this post.
