Low coolant light

[lil tahoe]

Ok so Im new here, Hi :thumbsup: I have an 02 tahoe with roughly 108k on it. I had to replace the fuel sending unit because at one point it looked like I was getting 600+ miles per tank (according to the fuel gauge) but other than that no real problems. All of the sudden my low coolant light pops on so I pull off to check and its full. Turn the truck back on and its gone, it does it every few hundred miles for no reason, any ideas? Plus I've had my brakes changed but they still squeak and Im being told there is nothing wrong with them?

bad sensor?

Make sure your overflow reservior is full to the coolant line also. I got a low coolant light on my Oldsmobile Cutlass and also found the radiator full but the reservior was almost empty. I filled it to the proper level and the light went away.

I vote bad sensor.

Well sorry, it wasnt the sensor, turned out the resevoir was low! Amazing what looking under the hood will do huh?
