Recently the water pump shaft had some play in it and made an odd noise from time to time. I ordered an new pump with a metal impeller instead of the plastic junk the original had. Bearing on the original pump was difficult to spin compared to the new pump. If I had gone longer with it, I would have had a seized pump and an overheated engine. Before ordering the pump, the alternator didn’t charge or spin freely due to the stiff water pump and its pulley. I’m glad its done and have more confidence that the cooling system is well sorted.
The failed water pump. Could be original but have no idea.
