I took the dogs to the park the other day and I stopped for beer on the way back home. When i came back out to the car coolant was leaking pretty solidly onto the ground. I got home and started freaking out. It was really hot and the reservoir was so filled it was overflowing. I started doing some research and really started freaking out. Head gasket is just what I need right now. The wife came home and said she topped off the coolant. She missed the markers and filled the whole thing up. I'm really hoping that's all it is. I'll check the radiator cap just to be sure it's not that. Any damage I should be worried about? Only drove about 30 25 miles. Thanks.
