Radiator - Temp Sensor Line at Bottom?
This is a 1994 Ford E150 with the 351 engine. I noticed that there is a outlet on the bottom of the radiator that has a hose connected to it with a clamp. When I removed it a lot of sluge came out and then I noticed that the tiny hole in the fitting in the radiator was plugged. I ran a wire into it and cleaned it out. I took a hose and run some water back into the hose and a lot of sluge came out. My question is .....is this a line to the temperature sensor by chance?

Not a temp sensor...
I have a '94 E150 w/ 5.0L and I have previously replaced the radiator. There was no temp sensor (or temp sensor "line") on the radiator. Temperature sensors are almost always on the engine itself.
On the radiator there is an upper & lower radiator hose, two (2) transmission lines (bottom of the radiator) and a coolant overflow line that drains to the ground (or goes to the coolant bottle if your van is so equipped). The coolant overflow line is on top of the radiator just under the radiator cap. See picture here...

It's a rubber line that is sometimes held in place with a hose clamp. Is that what you removed and cleaned?

The answer is that there is a line coming off the bottom of the radiator that goes to the temp sensor. I don't know if it is direct or how. After cleaning out the brass fitting my temp problem was solved The vehicle now runs fine. I didn't need a new fan, a new radiator, or the thermostat out, just the little hole cleaned out so the sensor could get wate from the radiator to measure.
