I was just told that the 7010 and the 7000 series have an issue with electrolysis in the block and radiator that could lead to sleeve problems and perhaps early engine rebuilds and that the antifreeze must have routine replacement and maybe even a special filter. Is there any truth or even half truth to this?

I don't think it is exclusive to the 7000 or 7010. I think you are suppose to change it every couple years or so in any engine because of that happening.

Causes of Cooling System Electrolysis Corrosion

Cooling system electrolysis corrosion can be caused by two things:

Worn out coolant. This is usually the result of not changing your coolant often enough. Over time, the corrosion inhibitors in every type of coolant wear out. For traditional green formula coolants, this can occur after two or three years or 30,000 to 50,000 miles. With "long life" OAT and HOAT formula coolants, the corrosion inhibitors may no longer be able to protect your cooling system after five years or 100,000 miles, which ever comes first (not last!). Once your coolant turns from alkaline to acidic, electrolysis starts to eat away at the metal surfaces inside your cooling system. Sooner or later your cooling http://www.aa1car.com/library/cooling_system_electrolysis_corrosion.htm#" rel="nofollow -

Seems that anything in the 301engine after themodel 200 tractor was produced is bad for that, theres something u can put in the water to prevent this

301's are worse than 426's and it's the bottom liner bore that seems to get eat the worst VS the liner.Monitor with test strips form "big truck" shops and add CSA as needed. That is what a water filter essentially does.

Any wet sleeve engine  can have this problem. AC engins are not the worst at this.  MACK

Baldwin Filters has a farm equipment maintenance guide that is very good and has a section on cooling system maintenance that goes into the reason why this happens and how to prevent it. Here is a link to the guide, let if load fully (the first part is an application guide) and then go to page 1087 "Cooling System Maintenance For Heavy Duty Engine". Pay particular attention to the paragraph titled "How do SCAs prevent liner pitting."  The whole maintenance section is very good and worth a read if you have time.
