Ok so the other day ago was the coldest day of the year it was around -10*F and the next morning i got up and noticed a pretty good size puddle in the snow. It was on the passenger side behind the front tire. It must have leaked out during the night but I did notice a little drip while I was letting it warm up and also towards the rear of the block I noticed a another drip which was a real light green color. They both smell like fuel but were different colors? This is my first diesel and I am a little concerned and was just wondering if anyone knows what the heck is going on with my truck. Any help would be great, Thanks Sam.
