I have an electrical part screwed into a brass T in the starboard block drain hole. The part is metal, circular and a wire plugs into the end. I have no idea what is is and am not able to find it in parts books. Does someone know what the name of the part is.

Look at the parts diagrams on volvopentastore.com

If its in an oil passage, it would be an oil switch.

In a water passage, could be a knock sensor or aa water pressure switch.
