    2 AM and I'm carefully driving the 308 down the road while the temperature gets up to normal. About 1 1/2 miles later, the little red battery light comes on and then temperature starts going up, quickly. It gets up to max and I pull it over. I let it cool off and slowly drive back home, stopping a couple times on the way to let her cool off. After I pull into the garage and get out, I notice she is leaking coolant (I think this is a safety feature of some kind after overheating).

    Anyone have any suggestions as to what could cause this to happen?

    If you are overheating and the batt light is on you almost certainly lost the belt that drives the waterpump and alternator. The 2 most common causes for this is a loose belt or a bad waterpump. When the pump beraings go bad from water intrusion they will often sieze or at least try to and they can do it intermittantly.

    If the pump does not turn easily and very smoothly either rebuild it or replace it.

    The same thing happened to me about two weeks ago. My water pump belt broke! Cost me about $400 dollars total to get it fixed (belt, labor, towing, replace coolant, etc.) You can check your belt by looking at the pulley right below your air filter.

    You popped the belt for sure. I have actually had that happen to me twice in 8 years.
