low coolant light blinks on/off

I recently did a coolant flush and fill and now the "low coolant" light is on. The light blinks brifely, turns off for three seconds, then repeats. I've bleed the air out and have made sure the coolant level is topped off. Any suggestions? Thanks.

I'm sorry, I forgot the car details.

I have the same exact car that had the same problem. I replaced the low coolant sensor on the right side of the radiator and the problem was fixed. It cost me about $40. Why it started after the flush was performed beats me, maybe its coincidence.

I have the exact same problem, 95 regal, flush and fill and then flashing low coolant light.

Hi. I replaced the coolant level sensor. The old one was very dirty and covered in junk. Problem fixed.

maybe it could have been cleaned all the gunk from the flush may have collected on the sensor just a thought for next time
