I'm replacing the water pump on my E150. This is the 2nd time I've done this within the past 12 months. I've replaced water pumps before but this one developed a leak. I think I failed to torque the bolts sufficiently.
What I would like to find is a reference photo or diagram showing the location of the (4) studs and the (3) hex head bolts. I took a photo before I removed the pump. But, I'm not sure they were correctly placed to begin with.
I have an exploded view of the engine that shows the water pump and I clearly see two of the hex head bolts. I think there is a third bolt shown but it is quite small.
