Purchased a 2010 mkz at an auction. Drove the car 10 miles before it overheated. When I stopped and let it cool I added water to the reservoir. Turns out the coolant had been drained. When I added the water and drove the mkz the water went to the oil pan. The oil looked like a milkshake. This Mkz has 133,000 miles on it. Yet to decide if I'm changing the engine or just the water pump and timing chain.
