I swapped over to a 2 row aluminum radiator 8 years ago when my brass radiator started leaking. Still going strong without a single issue. While I was in there, I also swapped out the water pump, hoses, and went with a 180 degree 351C correct thermostat. I was worried the 2 row wouldn't provide enough cooling after dropping in Classic Auto Air AC. However even on the hottest days sitting at idle, the temp stays at the bottom of the normal range on the stock gauge.Regarding electrolysis, I don't believe an aluminum radiator is anymore susceptible to it than copper or brass. Make sure your grounds are good, radiator isolated from ground, and don't use tap water.
