Well, still running hot after a new thermostat and a thermo-sensor on the
radiator. The mechanic, (who is not Vanagon savvy) claims it is not a
clogged
radiator because the whole thing is getting hot. After a few phone calls,
I,m driving approx 1.5 hrs away to a friends who has a vw shop with his
dad who thinks it's probably a plugged rad.

It has happened on their own vehicle and a pressure flush cured it. Hope
this is all it is. There's only approx 15,000 miles and 4 years on a
rebuilt head job with no exterior leaks, but I don't see how that would
make it run hot.
