I've just fixed a similar problem with my 1.6K. It was a duff sensor so it may be worth checking this too.
It's located on the water rail running down the near side of the engine. It's at the rear of the rail and has a single wire going to it with a spade connector.
Before replacing mine, I checked to make sure it wasn't an earthing problem (current to earth runs thru the water rail / engine earth).
To do this:
- unplug the wire from the sensor
- ignition on
- with a suitable scrap piece of wire connect (touch) the wire just removed to the casing of the sensor (the brass(?) bit)
- temp guage should shoot round to max
If this doesn't happen, then the sensor may be OK and it may be an earthing problem.
Touch the wire mentioned above to:
- engine
- chassis
- battery negative (if the guage does not respond with FULL deflection then it could be that up the spout).
in that order which should give you a clue where the problem lies.
Hope this helps and sorry response is a bit late, just trying to get my number of posts up ;-)
