I'm having the same problem now. My temp guage hasn't worked in years and i finally decided to fix it. I went and bought the sender at advance auto for 12$ and am going to put it in tomorrow. It is so damn hard to get to though so i'm going to have to take off the radiator hose. THe question I had was that the harness for mine is broken. Does anyone know where to buy a new harness to hook into the sender online or do i have to go to a dealership?
