Once up to temp the car will run around 100*C. It fluctuates between 100 and 90. Also there is no pattern to it, heat on or heat off doesn't change anything, idle or highway speeds is the same. It just stays in between those two numbers. The car has never overheated but my biggest concern is that this will eventually hurt the engine. Have you heard of anyone elses running at this temp?

I suspect it could be a bad waterpump. I just had to tighten the belt on the alternator and waterpump a while back due to squealing. Could it be that the belt has stretched and its not pulling the pump fast enough? A new belt is my next step.

I have checked all of the hoses and all seem to be free of any blockages. Could there be a block somewhere in the engine itself? If so would a flush help out?
