I have a suspicion that my thermostat is stuck open.  Some of the things I
have noticed are:
1) runs the best at highway speeds--constant 60-65 mph, guage at or below
led even during hot weather
2) instant heat up front in the winter.  My '86 took forever to get heat to
the front, this one ('85) gets heat within minutes
3) cold starts are not so good, runs great after 5 to 10 minutes.
4) gas mileage around town not-so-good, 16 to 17mpg, good on highway, 20 to
22.5mpg.

Are there any other symptoms?  I like the quick heat, but I think the
engine will suffer through the longer warm-ups.  If the PO left the
thermostat out, how would it run?  This van was stored for awhile before I
got it.  I would think it would have stuck shut, or is this the way they
are meant to fail (fail-safe)?
