my 2010 cobalt has been leaking a little bit of antifreeze in the last 2 days the temperature has not gone up when i am driving and it has been very cold could it be from the overflow tank
It could be a cracked tank. Usually if you are seeing coolant out the tank's overflow hose, the cap is bad. Get a new cap and just snug it down. If you tighten too hard, it damages the gasket.
i am going to the dealership tomorrow and having my oil changed and having it checked
