I didn't inspect my pump prior to having the recall pump installed. However, I do think mine was probably on it's way out. I have 125,000 miles on the truck and had recently began to notice a slight coolant odor around the engine bay after a decent drive. I never saw any leaks, but the odor was present. I did the upper radiator Y-pipe replacement last year and inspected that when I started to smell coolant but didn't see any issues on the Y. So, my best guess was the pump issue.
I'll have to keep a close watch and make sure I don't smell the coolant anymore. If the smell has gone away then I can probably assume the issue was the pump.
