Coolent temp flucuates

Hi all,
has anybody else noticed that the coolant temp gauge fluctuates from 90 C to 100 C?

All my previous cars kept the temp at the exact same spot, whether is was 30 C below or 30 C above.

Do you think I might have a faulty coolant thermostat?

Thanks

The other day it was 100 outside and the coolant temps were steady between 199 f and 204 f.

Re: Coolent temp flucuates

Thanks Jim, I'm starting to believe the variation in temperature readings is normal. I've read a number of posts on one of the other forums that suggest this.

FYI, according to my recent work order, the temp that activates the cooling fans is 105*C which is....you guessed it...221*F. Another thing to note is that 221*F digital reading also is dead smack in the middle of the temp "arc" says normal to me. Also, the thermostat opens at 90*C which is 195*F.
