Thanks Malcolm, great links, am going to try placing the sender in water @ 180F and see if I can recalibrate later today, article refers to a recalibration screw, which if present on mine could sort it. Will not bend needle though.
Interestingly the previous owner had problems with overheating, replaced the radiator but problem continue, but it did have an electric fan fitted to the front of the rad, which I have now removed. I have also replaced the pump with a higher pump rate one from Moss, reviews are mixed so be interested to see if it works. Also the fan blades were a bit flat so have increased the pitch, hence particular importance of the gauge!
Will report back, rgs all, Bill
