Is the pressure tank and its level sensor still part of the mix? Coolant level 
probes, and thier associated wiring have been known to give fits. Especially if 
the van has the earlier style of relay, that sends the gage to "overheat" 
readings, when the "low coolant level" is what is really wrong.

Subject: temp gauge shenanagins

Well, my AAZ conversion is running! yeah. thanks to Karmakanix. Runs
strong too. Only 300,002 things left to do.

But...my temp gauge goes slowing up to the red zone and the light
blinks. Stopped the first couple of times and the engine doesn't smell
hot, the oil temp hasn't gone up and the oil pressure is the same and
the fan doesn't even come on. This happened in 50 degree weather.

Can a short in the wiring cause this? Or something else other than
overheating?

Mike
