Water temp gauge

I have a mecanical Smith water temp gauge and futher to a overheating engine (I assume that was the root cause because of bad purging) my gauge is ending at 50° C when 'normal' temperature.
My question is trheefoild:
1.Does anyone had same experience and is the gauge broken?
2.If I need to buy a new one,my concern is the line lenght connecting to engine (from front to back) as normal replacement do not have the lenght for a GT40.
3.Can I replace gauge with existing connection?

If your system has air in it and the temp sender is mounted in the top of the intake it will not read correctly.

David,
Tx I will check this first

I believe if you remove the sender from the engine and drio the end into water you chould get a reading.

If that is the case then boil a kettle and drop the end in - it should read 100 degrees.(or there about)

If it doesn't then probably some damage somewhere.

I'll send you an e mail with details and prices of Smiths gauges from Speedy

ps I have nothing to do with Speedy - just had the info to hand
