    Hi,
    Can anyone help identifying the sensors on the top of the cylinder head?
    I understand the one on the left is a water temp sensor, but all diagrams i have seen show the other as a blanking plug.

    Many thanks IMG_2856.jpg

    I have no idea, but can say on the disco 200, def 200 and the early 2 litre derv, that back hole is used for the heater matrix.

    Both are water temp sensors. I currently have 2 in mine but I only connect wiring to one. Was cheaper and easier to fit the old one than buying a blanking plug at the time.
