Actually, the pitting comes after the gasket and sealant fail. If the gasket
is working, there will be no antifreeze under it so the type of antifreeze
doesn't matter. The phosphate free has to do mostly with those nasty white
deposits settling out and clogging things and the abrasiveness wearing out
pump seals and heater cores. It is mostly an issue with hard water.

The "Phosphate Free" issue has to do with corrosion control, and in the
vanagon........... avoidance of head pitting. which leads to head
gasket leaks - the very bane of Vanagon owners.
For my van I run GM's Phosphate Free orange biodegradable, 5 year
coolant mixed to a 50/50 ratio with distilled water. I also add a bottle
of Redline Water Wetter. I change the coolant out every two years,
religiously.
