Well today I was still having that running 3/4s hot problem with my 2.1l to
1.9l conversion.  I pulled out my digitool for digijet and at full hot it was
saying the temp II sender was giving me .05 volts.  So I thought this was too
low (perhaps it is just a bad temp sender since I did scavenge it out of an
old thermostat housing) and that the van was still running hot.  So I decided
to swap out the radiator with a known good one from my old '85.  Did that,
still 3/4s hot.  Finally I tried something that some of you folks suggested,
I swapped in a new voltage regulator for the instrument cluster.  That was
it.  Now it runs around 1/2 hot and as soon as the needle gets to the right
of the led the fan comes on.  So I wasn't having an overheat condition after
all, just a false indication problem.

Oh well, at least it is finally fixed.  I did see some good things happen
like I discovered the alternator was dead and I swapped in a rebuilt one
(tried to use the alternator from the syncro, but it was worn out).  So if I
can get the A/C charged up (pretty easy), she should be ready for the road.
Thanks for all the help.
