so i got home from hunting today and not driving my truck for a day and a half and i noticed a wet spot underneath. i check it out and it is antifreeze. i pop the hood and there is spray on the top of the exhaust manifold and some other places. this made me think the water pump and was leaking to the fan but i looked all over and nothing. i looked up from underneath to see the back of the head and it was all wet underneath the truck and up the engine. There is a threaded plug and a freeze plug under the fuel return line. i cant visibly see a leak but it is staying wet though the truck is at operating temp. I run my hand over the spot and it is wet but it smells like fuel. wondering if anybody has had a leak in that area

 

I had a fuel leak there once but not coolant.

 

There is a freeze plug on the back of the head and also a weakness of the head gasket on the right front and the left rear, right near the corner of the head.
