I did a quick search but didnt see anything. I had a coolant leak and when I looked for it, it was leaking at the T-stat. I fixed it and when I started her up I still had a leak that I couldnt see before. I cant tell exactly but it is dripping from just under and behind the camshaft pulley. There is nothing dripping from anywhere on top. I am wondering if my water pump has went bad and is leaking from the weep hole but i cant tell. I would hate to replace it if you guys think it could be something else.

 

Its probably the water pump. Lay under the truck and look up to see it.

 

You didnt say if you replaced the thermostat houseing,they will go bad and leak,just a thought.

 

Ya, it might be dieselsite that has a tougher houseing, I forget.
