My 1996 jgc v8 5.2 is still experiencing coolant sensor bad on the info panel. I changed the sensor between the a/c compressor and alternator and the one in radiator recovery bottle. Is there any more that needs replacing? The info panel shows the radiator with a flashing light is there a sensor in the radiator or waterpump housing?

You should have one between the lower Rad hose and another between the upper hose, do you and did you see them?

why does the coolant sensor bad light come on just replaced it this morning and went out tonight

I had the same thing, i replaced it and the light still comes on in my 97 gc, it only stayed on for like a min and ony did it once so far (i changed the sensor like 2 days ago) i figured it jsut needs to be reset or something but im not gonna worry about it unless it continues.
