2003 GRAND AM. Low coolant came on when driving, engine not overheating. No visible puddles underneath. Added 3/4 of a 4L jug, coolant kept disappearing. Checked underneath the car and could not see anything leaking out. Added radiator leak guard with the pellets, then added the rest of the 1/4 of coolant and cut that with water. Started my car up and drove 1km and the low coolant light came back on and the rest of the coolant has disppeared. Any ideas?
