Hi, I have tried searching but have not found anything about about my problem. I have a 2007 Edge SEL with the 3.5. Earlier today it started running rough and the temp gauge cranked into the red. I stopped the car and checked the coolant. There was non in in the reservoir. I had my son bring me some coolant. While waiting I checked the oil. It was way above full. We dumped in 8 liters(2 gallons) of coolant. I started the car and it was running fine so I started heading home, after about 10 or 15 min it the temp starting creeping up again and then hit the red. Just as I was pulling up to the front of my house it stalled. Looked at the reservoir again and it was empty. Checked the oil and it had gone up a lot more. This is the part that confuses me. There is no white smoke from the exhaust and the biggest thing is the oil still looks dark. It is not milky or frothy or anything that would point to coolant in the oil, but my coolant going down and the oil level going up points that direction, that is the weird thing. Possible water pump? Any thoughts would be appreciated.
