Whilst around with the radiator sh!tfight, I discovered that the factory coolant sender unit cannot be used to run Speco coolant temp gauges. Was a very long shot, but worth a try given the simplicity of the job. The sender must have a different resistance or whatever makes them work, as the gauge seems to read almost twice as high as the actual water temp.
I may go out and pull the sender out, to see what sort of thread it had, in the hope the speco sender will go right in. I had been holding off just incase Morpowa wanted to use the factory sender for the Haltech install. I am gonna hope they'll just use the ecu sender only.
Ironically, there doesn't seem to be a coolant leak from behind the water pump any more. No matter how hot I got the car, or how high it revved, the leak seems to have fixed itself. (now I know that never happens, so we'll wait and see. Hopefully the new gasket comes in from Toyota soon so I'll have it on the shelf when it is needed)
