View Full Version : Low Coolant but coolant level is fine.

The "Low Coolant" light on the dash goes on and off intermittently. For the most part it's off but it will just randomly turn on for apparently no reason. I thought it might only be when im going up or down hills but it will do it on flat streets too. I obviously checked the overflow tank and the level seems fine there (although its hard to see the min/max lines) but its approximately halfway full. Any ideas guy? Bad sensor or something?

Sensor shouldn't be much to replace... that would be my guess.

i agree with metal i had a gran prix that started doing the same thing up before it got wrecked. I had it scoped and it came back the sensor was bad i think it only cost me like 10 something at napa.

same thing has been happening to me mostly in the mornings when the Heater is on full blast. Its either the sensor or Low Coolant but either way I know im not burning any coolant or getting any into my motor.
