Thanks for all the input about the cooling system overheat problem I was
having.

Here is what I found:

The van would warm up rather quickly to about 3/4 on the temp display.  I
figured this was overheating and I would shut the van down.  However, I got
so mad today that I just said, "Keep it running".  Well it ran at the 3/4
temp and didn't rise.  I noticed that the lines to the front heater core were
full of air.  I opened up one of the lines until a little coolant came out
(this bled the heater system and that started working).  Then we felt the
radiator starting to get warm.  Finally the radiator got hot and the fan came
on as the gauge still showed about 3/4 hot.  The fan cycled on and off like
normal and both heater hoses were hot.  So, I replaced the gauge sender
(thinking it could be bad) and it still acts the same way.  The only thing I
can come up with is that the gauge is wrong somehow and that the motor is
running at normal operating temps (this is confirmed by the brand new raditor
fan switch cycling on and off while the gauge shows 3/4 hot.  I have bled and
bled the system and all the lines now seem to be full of coolant and all of
them get hot after the van runs for a while.  So I assume I am at normal
operation here.  Anyone else have the problem with their gauge reading high?
Can it be adjusted somehow?

Thanks for all the help,
Ken Wilford
