I looked under my truck and noticed a Antifreeze Leak I looked under the truck and noticed the antifreeze leaking around the crank shaft. I have never seen a leak from that area. I haven't pulled anything yet I was just wondering if anyone had something similar that could point me in a good direction before I start pulling parts off.
I looked up top didn't see any hoses leaking. looked all around the block. the only place I can see it coming from is behind the crank shaft pulley somewhere.

Looked at the engine (5.4) and I'd look at the water pump, that would be my guess since I had a similar situation on a 5.0. There is a drain hole in the bottom of the pump and when a seal goes you get e drip or worse and its directly above the crank.
Good Luck
