again, 1994 z28, 155k miles.... The coolant light came on. I flushed the system twice, which turned the light off for a short time. It then came back on, I reset the computer and it continuest to burn. Anybody know where the sensor is? Anybody ever replaced one? Difficult ? Thanks, Mark

just out of curiosity, did you blead the system?

 

hey there, I got the same problem, bad sensor was the diagnosis. If you get more info on it, can you send it to me if you dont mind, if not its cool.. Thanks

 

I drained the coolant from the drain valve in the bottom of the radiator in front of the passenger's side wheel, and let the engine idle as i refilled at the top and let it drain at the bottom. I repeated the process before refilling with coolant and calling it quits.
