A while ago my 2wd Saff burst a water pipe whilst i was driving along the motorway, i lost all water and the temp gauge started to rise i stopped before it reached the red to investigate (neddle into N of NORM).

I have now fixed the broken pipe and taken the car out, driven down the motorway 60-70mph, and noticed that the temp needle sits higher than half way, when before it sat at around 1/3 up the gauge. The radiator and turbo coller were both hot (water circulating).

Any suggestions as to why the gauge is showing higher now ???

May the temp sender be affected from the loss of water a slight overheating ???

thanks for any help

Hi,
May the temp sender is covered now by deposit (from overheating) that change his reaction.
Remove sender and brush it.
And check wire connection.

will give it a clean and so if it returns to original position.

 

the overheating may have damaged the rubber insulation around the sender centre post, this may be making it read high , as the dilectric strength of the rubber breakes down it can start conducting which would result in the centre shorting to the outer - if this happenes the gauge reads full scale and goes right to the top....

 

ordered a few new sensors including this one, better to be safe and know what is going on with confidence, than sorry.
