I'll go with the flush before replacing the water pump.

My parts store has nothing with oxalic acid in it.

But, I do find wood bleach at my hardware store that seems like what I want. I have found a couple places on line that say to use about 16 Oz. in my system (filled with water, not coolant) run it to temp for a while, then drain and refill with clear water and about 1/4 cup of sodium carbonate (not sure where to find that yet) and run to temperature to neutralize the acid. Drain that and refill with 50/50 mix of water to coolant.

Hopefully, this will address the issue. Certainly worth a try...
