You'll have to pull the pump to inspect the impeller. Given red, gritty gunk, I'd be much more inclined to think the radiator is plugged. If you have another (maybe even different type) radiator, clean out the system and kludge the second radiator in. Observe indications of flow through the (open) fill spout. Or, take the existing radiator to a radiator shop to have it cleaned out and flow checked. Craig
