I purchased a 2004 Ford F-250 a few months ago. I haven't had any issues, other than changing out filters, cleaning, etc. When I first checked the coolant, it was low. I topped it off. This was September or October when I purchased the truck. 2 days ago, it was low again, so I topped it back off. This morning I noticed a huge puddle under the truck. It looks like a pretty good size leak. I have been driving it up to this point with no issues. No Check Engine light showing, and no stored codes.. It is not my daily driver, so it has sat for 2 days until I noticed it this morning. It's on the passenger side of the engine. I can't see anything wet from the top of the engine. I have attached 2 pictures from underneath. They are not the best, as it was getting dark when I took them. Its running down from somewhere and I'm just curious if you guys can give me an idea where to start. I can get some better pictures tomorrow if needed.
