Fan/Condenser/Trans Cooler Spacing

For the sake of clarity, here is a picture of the gauge:

The temperature gauge is in the bottom left pod. There are 6 "vertical" lines within this gauge. I will refer to the two middle ones (the two lines the orange indicator needle is between in the photo) as the left one (for the one to the left of the orange indicator needle) and the right one (for the one to the right of the orange indicator needle). Between the left and right lines I am calling the safe zone.




I was able to fill the system up with coolant last night after I installed the new 195 degree thermostat and took the truck to work. It is about 8 miles with speeds going from 25-45 with the possibility of stop and go traffic. Not to sure about the temp this morning, Id say in the 70's with high humidity.

When I first started out the gauge was fluctuating around the left line. Which is okay. After awhile it seemed to hold steady around the left line. I am okay with this. I took this as the system "breaking in" the new thermostat. So I hit the first traffic light behind a couple cars. The temperature needle increased to just below the right line. Higher than I would like but still within the safety zone. Once I finally got through the light it was Pittsburgh hilly roads traveling about 30-45 mph. The gauge still held within the safety zone but about 2/3's of the way to the right line. After about 3 miles the gauge was reading about a quarter away from the left line. I then hit stop and go traffic again. The gauge didnt seem to get as close to the right line but was still reading about halfway between the left and right lines. Once I finally got the truck parked is when this picture was taken.

Would you consider this "normal"? My 68 dart does not have this type of fluctuations with this type of driving



for further reference, I consider normal range on this gauge to have the needle hovering over the left line with being a little to the left of it. or thats where it stays on high way driving. Before I changed the thermostat the needle was to the right of the right line. The gauge does not read that high when it has been running and you shut the truck off, let it sit for a couple minutes and start it up again. Hence why I changed the thermostat. It didnt get that high today, but it is still higher than it was before I switched to this 7 blade clutch fan (it originally came with a 5 blade clutch fan on it)
