    Coolant light stays on
    I have a 2001 chevy Tahoe and the coolant light always stays on. I checked the coolant it is normal. It is not overheating. It is running perfect.

    Probably a bad sensor. Also could be a problem with the engine control module.

    Either replace the reservoir for $50 or disconnect the sensor's connector and monitor the coolant level on your own. It's a common problem, where the float hangs up.
