If your t'stat is bad, your pathy will overheat. they are quick to let you know. if it hasn't been changed in a while (since last t-belt change or before) it is time, as is the water pump.

pathys are only allowed 170 degree t'stats. if you run the motor hot.. you will warp the heads.. which is not good. remember.. everything but the actual block on these motors is aluminum. very sissy when it comes to excessive heat.

 

as for your needle location.. yes, that is at 170 degrees/working temp.

 

another way to tell if your t'stat is bad is a jumpy temp gauges (goes hot to cold.. to med in a short period of time driving)
