CHEVY LOW COOL;ANT SENSOR

2001 Chevrolet Impala

Engine Cooling problem
2001 Chevy Impala 6 cyl 225000 miles

I had the radiator replaced on my 2001 Impala and the low coolant light came on about a day later, I tried a few things before I changed the sensor. This worked for about a half a day and it came on again.
I have checked for air in the system a number of times but the coolant is never below the sensor.
Any ideas?

Is the sensor pointing in the correct direction

Good question
I put it on the way I took the old one off
But I just had the radiator replaced so who knows if they put it on right

The connector should be pointing down

You have to make sure all the air is out of the system. If it is not when the engine sucks coolant out of the radiator it could drop below the sensor. When its shut off it maybe above it but not when you are driving down the road.
