I noticed my 07 G6 was blowing cold air rather than heat when the car was parked or stoped at a light, I noticed my coolant was low so I filled my overflow tank to the cold fill line with recommended dex cool and went for a ride, my heat returned nol problem. 4 hours after the ride when cooled down I checked level again and noticed it was considerably lower so I added more only this time I mistakenly added abot 3/4 of an inch too much.I went for 15 minute drive and then noticed fluid leaking.I once again cooled car started and when it warmed up I noticed fluid steady drip from what seems to be a hole under the overflow tank (clearly the hole belongs there). The level is still just above the over flow line.I dont know if this leak was happening before but I dont think it was. Is this hole under the tank suppose to leak maybe due to my over filling? Or is this a sign of a bigger problem. Please help any info or help would be very useful
have the same problem?
