Water pump leaking?

Yesterday I went out to my buddy's shop for some crossmember repair,I popped the hood to show off my freshly cleaned engine compartment,and the engine was partially covered in what appeared to be spots of coolant.I wiped it off as good as I could,made sure all the hose connections were tight,and eyeballed it and all looked OK.When I got home,I checked it again and there was even more coolant over everything,seems to be spraying from the water pump area.Would a leaking or worn out water pump cause this?Its been on this engine since installation in the late eighties,big block chevy.

BEaring seal on the pump is shot. The fan will blow coolant all over the place as you have found out...

Be sure to look it over closely. My wife's car had a coolant leak too and I thought it was from the water pump since it was leaking from that area. Turned out it was from a pinhole in the plastic radiator tank that sprayed when pressurized in the direction of the water pump. Luckily I caught it before I changed the water pump. Later I bought a 1996 Chevy Silverado that had a coolant leak, which I thought was the water pump. I changed out the water pump and the leak was still there. Turned out the intake was leaking coolant and was dripping under the truck, which I mistook to be a blown water pump seal. Of course, I resealed the intake which fixed the leak. Now I have a spare water pump for my pickup!
