Coolant Temp?

[onefastman]

I have read around and found a variety of responses as to what is a normal coolant temp. My expierence (none with water cooled p-cars) has been with air cooled 911's, and bmw's. All of my bmw's have the needle in the middle, always. My 98 boxster is in the middle of the 180 and the next tic up all the time, sometimes just a bit hotter. I am running a 15w50 oil as well. The temp doesnt change in the weather I have driven it in (50-85F) nor does driving style change it (crusing at 75 or wot for extended periods).

Is this a normal operating temp?

If not, will a lower temp thermostat help or maybe flush my coolant?

Thanks for the advice and reading!
