I am trying to figure out whhat is leaking out of my truck. I noticed this once before in my parents driveway, but assuned it was their jeep. My truck has been sitting in the driveway for about a week. It snowed last night and when I moved it to shovel, I noticed green liquid in the snow. The easy answer is antifreeze, but it was where the rear of the truck was. Any suggestions? I dont see any leaks anywhere either.
