Jeff, I don't see how this can be. I have seen this scenario:
Vanagon is overheating due to water leak or radiator fan not working.
Person repairs water leak or radiator fan and perhaps adds a bottle of
Bar's Leak because he sees some seeps as well. The overheat condition
has liquefied a bunch of corrosion that was happily sitting in the
bottom of the engine water jacket and this has been pumped into the
radiator. Now the van starts to overheat because of a plugged radiator
but it is not the Bar's Leak, it is the crud that got suspended in the
antifreeze and was flushed into the radiator. I have looked inside
these radiators and the trash in there is usually orange (not black).
This is nothing but corrosion sludge.
That has been my experience. I have never seen black sludge inside bad
radiators only orange. If you weigh a bad radiator it will weigh
several pounds heavier than the new one when it is empty. Are you
telling me that a small bottle of Bar's Leak that weighs only a few
onces is going to plug up a radiator and then cause it to weigh several
extra pounds? This is sludge due to corrosion.
