I posted here awhile back about having inherited my fathers Cadillac Eldorado with a 501 C.I. engine, and I'm still trying to get on top of the learning curve. Here is my latest dilemma: Looking at the engine heads there seems to be two temperature sensors screwed directly in to the heads. One is on the right-hand side all the way forward, the other is on the left-hand side all the way aft. There is a single black wire coming from the one up front and a green wire coming from the rearward one. They're not intersecting any oil or coolant passageways that I can see, so my conclusion is they are measuring the head temperatures directly. Did Cadillac actually make an engine system this sophisticated back then and if so how do I tell if it is working? Or am I even on the right page of music?
