Anyone ever use
 

Anyone ever use those radiator stop leak fluids? I used some today jus untill I get my new radiator. It's keeping the coolant level and I see no leak now. But my low coolant comes up on my dash every start but then goes away.

I'm curious if maybe the sensor is messed up now? Or something else.

Sensor is in the tank in the engine bay. Level should be kept at about the line (which is about half). If there is that much in there then maybe the sensor is bad.

Do a FULL flush when you get the new radiator then see if the sensor still has problems.

Yup full flush was already accounted for when I get it. Thank you tho!
