2014 3500 - Low Coolant Sensor issue -
A couple of weeks back I got a low coolant message. I saw some dripping from the side of the radiator, it turned out to be a bad clamp that was letting some spray out of one of the hoses. Issue resolved, all good.
The low coolant light is still coming on. The level in the bottle when cool does not change. There is none in the engine oil. It is also not low according to the bottle.
I pulled the wheel well and jumpered the wires to the sensor, and the light goes off. I ordered a new sensor and replaced the old one, and it still says coolant low. Part number is 68354536AA.
Is it possible that I got a bad sensor? Sure. But I'd like to figure out a little more about the coolant bottle itself before I get another sensor (the first broke coming out, and it was a pain getting the remainder out).
You can't see into the bottle, so I'm trying to figure out if there is a baffle or something in there. The coolant level is visually fine and stays in the same place when cool. It's a bit over full right now, in fact.
Has anyone else ever run into this, or does anyone know if it's possible the bottle has baffles or anything that could allow the level to be different in different sections? I can't imagine that's the case, but I'm trying to figure out why two sensors would be bad.

Reason: added part number for sensor
