What do you think?
Wife was driving car, suddenly overheated, both light and temp gauge almost pegged. Then oil light came on. She pulled over within 2 minutes. The cooling reservoir was empty. I let the car cool, filled it with fluid and the car seemed to run fine. Shut it off and coolant poured out from beneath the car.

 

Have you checked for a blown hose? Maybe the sensor oring failed.

 

I guess I'll need to fill it up tomorrow and see where the coolant's coming from.
