Stuck water pump?

[EccentricMagpies]

'74 360 car

I just started the car for the first time since it was Dyno'd .. maybe 3 years now. The car will run and idle, but the blade does not turn. Water pump seems to turn hard by hand.

the belt seemed tight on the alternator but I can't imagine this as any issue.

is this obviously bad water pump issue? I would have thought this water pump was the one used during the dyno of the motor.. but it's been too long for me to remember that detail when I picked the motor up.

Wonder if there might be some other simple solution?
Thanks,

Sounds like a bad pump to me.

I’m not following something. If the fan didn’t turn and there was a belt on the water pump pulley you should have murdered the belt? Like smoke and all. Do you have clutch fan or is it pump, pulley, fan?

Good point. I was assuming the belt was removed when trying to turn the WP by hand.

It is a clutch fan. But the pulley itself wasn’t turning

Oh wait. It is slipping. Never mind

Is this a Keystone Cops routine ? Was the engine ever installed or has it just been on a stand since being built ? Fluids drained ? Water only no coolant ? Like said, it is easy to see the difference between a stuck pump and a stuck fan clutch.

The motor went from Dyno to sitting in the car.

Well, that will be the next thing. Where there might be leaks.
Right now, I only have 4 quarts of Trans fluid in at the moment since it was a rebuild, so I still have to ease that in. (at least from what I was told)

Right now, just happy it starts relatively easy
