My car is overheating, no heat - so assuming I'm having a problem with coolant system flow. Thermostat was replaced about a year ago because it was easy while doing repairs on the front of the engine, so I'm worried it might be the water pump. Anyone know of a good way to test?

I just did a waterpump. Mine was rattling and would turn hard the power stearing went out then the heat. If you don't hear any grinding and your pump spins then I would say you might have some kind of clog within the system. Have you noticed any leaks? Is the radiator full or is the coolant level slowly decreasing. Is there any coolant? Loosen up your belts spin the waterpump. Check your coolant levels. Listen for strange rattling/grinding noises. Try flushing the radiator.

Coolant level has been stable, and there's plenty of it. No grinding noises but I heard that the impeller blades have a tendency to break off...

Found this
Maybe it can help.

Hmm car just started making a screechy sound - like belt noise - maybe this could be the pump going out? Going to try tensioning the belts to see if that fixes it...otherwise looks like I might be replacing the pump.
