210 seems a little high, is it always that high or does it vary between 197 and 210? Check the radiator for dirt an debris in the cooling fins, backwash it out if needed. Are the cooling fans operating properly? A 2000 model if the cooling system has not been maintained properly it could have a partially plugged radiator internally. Has the radiator been flow tested? The temperature during a hot soak as you described is really normal, it's just that you have a slightly higher than normal running temp so the hot temps are going to be higher. Of course there is a possabality that the gauge is inaccurate, to find that out you would have to install a manual gauge so you can watch the temps through all drive cycles and compare the two readings.

No it just run's at 210 all the time. Should I have the radiator flushed? Before getting the water pump installed?

I would have the radiator checked for flow first, most shops have those little lazer temp guns and can see a problem with a radiator core by testing the difference between the top and bottom of the radiator all the way across the face of it. If they do find a problem you might be better off replacing the radiator or at least a recore.

OK thanks I'll try that and give an update when I get it replaced thanks for your help Joel
