Mine runs between 95-100*c all the time. I've gone round and round chasing small coolant leaks, swapping thermostats, changing an aux. pump and just yesterday a waterpump, etc. so I know the cooling system pretty well now. after swapping from a 87*c to a 80*c thermostat my gauge moved down not even a needle-width. Now with the new waterpump it runs a needle-width higher. My cooling system is flushed and clean. I can put my hand on the upper hose when just off the highway so I know its not too hot. I have come to the conclusion that the gauge is a little wonky. I use the gauge as a "trend indicator" rather than an absolute instrument. If your car runs at 100*c all the time, everything in the system is up to snuff and it doesn't boil over there is nothing wrong with the system, drive it and don't worry about it. RT
