Temp sensor

Thing is, I really don't see any other reason that the temp sensor will not work.

I tested the sensor in a bowl of boiling water and connected it up. The gauge moved all the way to the middle.

Upon installing it back into the car, the gauge only moves to the middle of the "c" on the gauge. I can only think that it is caused by an air bubble near the sensor or something.

What do u guys think?

well, it could be the sensor itself, it functions, but out of scale! normal opertaing temp (middle gauge) is about 82C, boiling water is 100C!!!
a temp sensor here in italy costs like 3-4 euro, get new one and see, if still wrong, then check the gauge itself, it also might have some part burned or something. there was a guy with a Carina E recently on the Bulgarian forum, and his gauge had some part burned, so it always went to the max temp, while the real temp was in normal range, he changed it, and the thing went back to normal. so concider that, rather than a bubble, which is almost impossible, in my opinion.
