Low Coolant Light

**BWA2110** · 04-30-2009, 04:27 PM

My low coolant light will come on after driving about 20-30 minutes. I know my coolant is full, but I am not real sure what exactly is going on. I was talking to a couple of people and they think it might be an air bubble in the system not allowing for proper flow. Anybody else have any ideas. Also if I was going to do a coolant flush is it any different for an LS1. I have heard it can be complicated. Any help please.

Its the coolant level sensor.

Its located at the top passenger side of the radiator if I remember correctly. They get gummed up with coolant and read incorrectly, causing the light to come on.

As long as you're coolant level is topped off and your temp gauge is normal, don't worry about the light. You can unplug it from the rad if you want as well, that will prevent the light from coming on.
