The needle has started to dance about like a Thunderbird puppet. Is it 80c or 120c. Before operating on it, is it likely to be repairable. If not anyone got one they want to sell.
I also have problem with my gauge. It does not move.. When u say the sender unit, do u mean the one connected to the cooling water? I`ve tried to change it, but it didn`t help..
There is a check you can do it tells you how to do it in the Haynes Manual. The sender unit I replaced is the bit ! that goes into the engine nothing to do with the gauge itself - sorry if i can't be more helpful but I'm not too technically minded
