I am chasing a water pump area leak. It doesnt seem to be from the pump itself. I pulled the radiator plug, took the fan off and pulled the shroud. Looking more closely it appears to be the housing the pump attaches to. Perhaps this hose mentioned above is leaking too.

I am trying to find a schematic of these parts to get a better idea what I am dealing with. Any suggestions?

Anyone suggest where I can get the hose and what ever I need to seal the housing?

Thanks.
