comment Can I drive a car with only water and no coolant if it has a leak?
@JuannStrauss - It is interesting that you mention that. About a year after this happened the car did blow its head gasket. It caused the engine to be flooded and as a result we had to replace it. Perhaps these were just the first signs of the gasket going.

The first thing you would try is in essence what I did. See my edit for more details.

Good point about the cold water in a hot engine. Although I did not end up doing this, I had considered buying a gallon of water from a gas station and might not have even thought about this common scenario which can be easy to overlook.

Kind of banking on a small leak. If it is out of hand then AAA will pick up the slack. Mostly I was concerned with whether or not to just use water in the system while testing to see how bad the leak/situation was.

I went to the dealership and got some coolant from them to use figuring it would most likely help at least a little to have some in there. Do you think I should stick with water or use a mixture? Silly question: the overflow reservoir should not be empty, right?
