Though I think it might still run too cold while I'm moving....

What started this whole escapade was that when I would fill the rad and put the cap on and shut the truck off after a few minutes you could hear the coolant rushing out. I was always filling the radiator back up with exactly the same amount of coolant.
So I replaced the thermostat with a 195 vs a 180 and still had the same issue. I was reading and people were saying that you can tell if your water pump is working as you can the coolant pouring back into the radiator which I did not see. So this is when I picked up the temp gun to verify what I was thinking as I was told that the upper rad hose can get warm without the thermostat opening due to steam and or residual heat.
Now without the fan everything works as intended and makes me wonder if any of this was working properly before I did the rebuild on the truck.
PS.... The fan in question is the one on the left with the flat rivets. Apparently using this with my truck now is a no no so I will have to pick up a clutch fan to use instead.
