    Does anyone know where the water temp sensor is on an 83 sub? My gauge doesn't work so I've got to find the sensor. Thankx

    Look on the driver's side between the front two sparkplugs (#1 and #3). There will be a green wire going to it. Try to groud that wire out on the manifold and see if the gauge pegs out. If not, then you have a cut in your wire, or a bad gauge.
