Review on ⚙️ ACDelco Professional 252-920 Engine Water Pump: Premium Performance & Reliability for Optimal Engine Cooling by James Baker

Update 1-31-20 Coolant is still moving Good: Comes with a gasket in case you were wondering Seems well balanced and mounted like all the other pumps. Use a burr-free metal impeller. I've done my best with a small file, but now there's metal instead of a small piece of plastic floating around in my cooling system. I think the bearing is usually the point of failure, I just don't understand how you can lose an impeller blade. I suppose if I did I would want the plastic to avoid damaging the block on my Cummins. Bottom Line Refrigerant flows back into the system. I can't say whether the stream is better or worse. but it flows. If I had to do it again I would order it again. When things go south I'll post an update.
