Low Coolant light.

[adoucet11]

2017 Chevy Duramax, Low coolant light comes on sometimes.

Checked top coolant reservoir, it is filled to the top. Checked bottom reservoir is has about a inch to inch 1/2 in it.

So to me it not low. But if the bottom is the one to fill how the hell I get to it?

Coolant sensor issue. Common problem. Mine does the same thing. I just ignore it now. Only fix is a new reservoir but it uses the same design so it might happen again

Paper clip the plug…cheapest redneck fix.
