I have a strange water temp gauge issue. The gauge sits at zero when cold and comes up gradually when warming up then goes off the scale quite quickly. The sender unit has been replaced and no change, the engine is warm but not hot and no signs of boiling or hot spots using a heat gun when the gauge goes to the moon. Thus I presume it is the gauge that is faulty. There are no new gauges listed as available - does anyone have a gauge they want to sell or give a good home to? Please PM me.
