Yup, when I took out the old sensor, it came apart. They are very fragile.
When I am "burping" the system I drive my truck up my "oil change ramps" so the radiator top is higher than the heater core. You will notice that the heater core intake lines (left side of firewall) are higher than the radiator spout. That means air will get trapped in there unless you raise the front of the vehicle.
You can try the ramps, open the rad cap and start the truck. As it gets warm, the air will burp out.
I am running a 180* t-stat, and my truck runs very cool. These trucks actually run very cool when the air is out, unless the TRANNY is getting hot. The tranny fluid will raise the fluid in the radiator. Dodge knew this for towing purposes and installed the external tranny cooler to take some heat out of the tube in the radiator.

I replaced the sensor, still the same thing. On the highway it reads normal temperature, but in the city it jumps between what I'm assuming 180 and 220, and its only 35 degrees out. If i get on iit, it cools down. The water pump was replaced a couple months ago, and i did not replace the thermostat, which i am thinking is the culprit, but I'm not sure. It never fluctuated like this before. I also suspect the water pump, although it was replaced recently
if it cools down when i punch it, like i said, normal temps on the highway.

If you have to jump on the gas to cool it down some, then that tells me that the clutch on the fan is shot, replace the fan and your worries should be over. Moderate 35 degrees one way or the other means the fan is locking up and unlocking

Well guys, waste of a thread �� i suspected thermostat, so i replaced with a 195 stant superstat, guess who put the thermostat in upside down when i put the manifold back on... All is fine now. It's the little things that always bite you in the a*s! Thanks for the replies guys, but as always it's just me doing something stupid ��

Another is rude noises.
Make sure that it is indeed the pump before you throw money at it though.
She's not leaking... But I smell that bitter sweat coolant smell when I walk around the front as its running. I notice it most when it's warming up to operating temperature... Like when I get up in the morning stop at the store and walking by it I smell it. It's not like whooooah but coolant has a very sweet scent so it's easily identified
