The reason that I'm not focusing on the radiator at this time is that
this happened suddenly. It never overheated until around Christmas,
and suddenly I have a spate of little overheating issues. Filling with
sludge is the kind of thing that usually happens slowly. I know there
are exceptions but it seemed to come on pretty fast for something that
normally takes place over time.

My wife ad an acura once where the metal pin that goes into the frame
above the bellows broke. It would run differently depending on how the
pin was cocked, which would cause it to either take forever to heat up
or to instantly overheat randomly with each heating/cooling cycles.
And sometimes it ran normally. What a booger to locate and fix.

Glad I'm working on a vanagon this time... except for pulling the rear
seat to get to that split heater valve. I hate that job on a vanagon,
I would rather pull the dash.
