Low coolant light on my 99 Camaro ss Hi guys I kinda have a problem on my 1999 Camaro ss . Low coolant light has come on my car checked my coolant it's full and put a new coolant sensor from O'Reillys auto parts store . Went off for a few days and now it's back on . Can the radiator cap cause this problem? Or is my new senor bad ? I know it's something minor couse no leaks any wear . I just hate to give 80 bucks to the Chevrolet dealership or you think I should get a coolent flush?

Issues with that sensor are a somewhat common problem, I seem to recall others reporting that the aftermarket sensors don't work very well (as you have discovered.) OEM sensors are much better, but they too are known to fail over time (especially if cooling system maintenance hasn't been the best.)
A coolant flush likely won't help if the coolant is already clean. You can either try an OEM sensor or just disconnect the sensor and forget about it.

Even with only 6,800 miles, the coolant should be changed if it's still from 1999.
My '98 has only 17,700 miles but it's had several coolant changes over the last 18 years.
That aftermarket sensor will likely be problematic even with fresh coolant but, regardless, it should be flushed if it's still original.

My coolant sensor gave me an alarm 3-4 years ago following the coolant change. I drained some fluid, cleaned up the sensor probe with a fine sand paper and steel wool, and it hasn't been an issue since. In many cases, all you have to do is remove the a light layer of gunk or oxidation from the OEM probe. What was interesting to me is how easy you can pull that probe assembly out once the spring clamp is off. And even with a tired spring clamp, it can back out with minimal force. Seems like a lousy design to me where you can end up with a "designed" 1" hole in your radiator with the probe popping out. And don't get me started on how they designed that spring clamp either.
