I live in Idaho, but work in the oilfield in ND. I was getting ready to head home and noticed a coolant smell. Reservoir was low. Looked all over, couldn't find a leak. Checked the oil and guess what, I got a chocolate milkshake. Car was running fine and isn't making any noise. Obviously I'm looking for ways to get it home 1k miles away. Car is a 2011 pp with 89k. Waterpump? Or is there something else I should be looking for? If it is the waterpump, can it be changed out with the engine in, or do i have to drop it?
