Hi. I know this seems a common thread but one problem I've had for the last 12 years is the temperature guage steadily going up to the red! I've changed the sender a few times over the years and the voltage regulator ( which presently reads 10.3v). I'm pretty sure the engine isn't hot.I've resorted to taking the thermostat out for the summer! I'd love to know whats going on. Any ideas appreciated.
Temperature guage reads high

Flush it an see if it still does it
Check rad not blocked or air in coolant
Borrow laser thermo and measure temp to rule out injun being too hot
Take stat out and test it or just replace they’re cheap ( stick in a pan of water and boil it see if it opens even if it’s new especially from ****part)
Water pump on way oot
Earths on stabiliser and sender
Install a Capillary thermometer

Dodgy sender. If it's not over heating when in the red, it's the sender. Presuming that the sender is in full contact with the head, no PTFE. I've a good few sensors, none are the same resistance. I swapped until I had one that was nicely in the centre.
I recently replaced sender and you're right they all have different resistance readings. I notice a 'genuine' Landrover sender 560794 made by Britpart in Poland is about £26 and a standard Britpart one made in China is less than a tenner! What do you do? Does anyone have any resistance values for the sender?
