02 GP GT - Low Coolant Light came on and stayed on for about 6 months. Coolant was never low the whole time. I replaced the sensor with a new GM one. Light went of and all was well for a day or so. Now the light goes on and off from time to time. May stay on 5 minutes and might not come on for another 30 minutes, might come on 5 times during 30 minutes etc. Temperature hand holds steady at big mark between the 160 and 210 and coolant shows full always.
Could this be air in my system? When I changed out the sensor, I just stuck the new sensor in and added a little coolant back in the reservoir. I did not bleed it. I'm thinking air in the system would make the temperature fluctuate, but mine stays steady? Could air in the system cause this sensor light issue with no temperature fluctuation?... or maybe the new sensor is junk?
