You are not corrected because you were not wrong - simply painting the picture with a little too broad a brush. You are 100% correct in pointing out the ill effects of certain OAT formulations - specifically DEXcool and others which still rely on 2-Ethylhexanoic acid (2-Eha) in their formulations. In older cooling systems those formulations WILL degrade solder joints and precipitate out lead (solder bloom) although it takes some time. But the industry has caught up and there are extended life alternatives that don't have those problems. The trick is knowing enough to tell the difference when reading the label which is largely sales hype written by a marketing grunt not an engineer or chemist.
