has the temperature switch earthed out ? That will give a high reading. Does the engine still run smoothly

hi yes the engine runs smoothy water is running through the rad and stat so every thing has not froze

Try the connections to the engine coolant temperature sensor, unplug and see if the terminals are clean.

It will look similar to this:

Change the coolant temperature sensor in the thermostat housing , i had the same problem on a 960 wednesday ... ( same sensor , similar engine )

well thanks very much for the advise but as normal nobody has the things in stock when you need them ive unpluged the sensor and cleaned the connections and now the engine symbol light but think thats because the temp sensor is playing up
thanks to all the feed back
think its going to be a great and costly start to 2010

volvo dealers wont stock this but can get it the same day if you order before 9:30 am ...
£28 i believe .... No it wont do harm short term , at least you know your engine isnt actualy overheating ...
