Hi there

Could be the temp sensor, located under the diesel pump on rear of cylinder head.

Almost certainly as Chris suggests. Will add though, make sure that you get the same colour part - if your original sensor is 'grey' and you fit a 'blue' sensor (as the parts catalogue suggested for my first Galaxy) then you don't cure it. Also, buy a new spring clip and rubber seal at the same time so that if/when you drop the original and it disappears, you still have one to put back in. It is reasonably easy to do from underneath. Not too much water comes out, and you can actually see what you are doing.

 

Use a mirror to check the colour before you go to the shop. Somebody did a 'how to' with pictures on here. Try doing a search.
