Bad water pump?

[Muddytruckin]

so I'm not sure if my water pump is bad or if my radiator is. When looking into the radiator with the engine running I can not see the coolant flowing, it just kinda sits there. Water pump and radiator are both original. I can see some very small debris in the radiator but I wouldn't think it would be enough to stop virtually all coolant flow. And ideas on how to tell which one is bad?

A water pump will either start leaking out of the weep hole or the bearing will make noise telling you it's gone bad. I have seen one water pump that the impellers were actually corroded so badly that there was nothing left of them to move the fluid.
Thermostat could also be bad but let's start with this question, is it running hot?

 

[Muddytruckin]

Yes, it's running hot. She's not road ready yet so i had it running in the driveway and shut her off when it got to about 215-220. Thermostat is new and I drilled 3 small holes in it. Using 1 14" electric fan.

Also won't be able to hear the bearing over the gear drive.

Does the lower radiator hose have a spring inside of it? The suction can nearly collapse the hose if the radiator has some flow issues..

 

[Muddytruckin]

Yes there is a spring in there. I'll probably get a cheapie water pump for $30 and put it on. If I can see it pushing water through the rad good, if not I'll get a new rad. Thanks for the tips on what to look for!

The prices have gone way down on battery powered infrared temp guns. Start at about $25.00 now. Great for checking temps at various location while the engine is running.
