Got home from work today and my D is leaking radiator fluid. It was raining outside so i only took a quick look to see where it was leaking from. It was leaking onto the cam shaft pulley and spewing it everywhere until i turned the truck off then it was a solid line of coolant dripping from the cam shaft pulley but not leaking from the pulley it self? Is the water pump right above it?

 

if you mean crankshaft pulley, then yes it is located right below the water pump pulley

and i would open the hood and look down from above to see where it is actually leaking from, however chances are its your water pump.

 

Like shrp said if it's leaking on the crankshaft pulley it is the water pump, also you should check the thermostat gasket/housing because I've seen it more than once where it will leak out and down the front side and appear to be a water pump.

While replacing the water pump, if that's the case, it would be a wise idea to replace the serpentine belt at the same time because coolant wreaks havoc on a serpentine belt.
