The fan is working fine. At first I suspected it, so I wired a switch
to it to turn it on manually. Running it on high does not help because
the rad is not hot anyway.
Both the front and rear heaters are producing lots of heat. If I reach
under the van, the 2 heater lines are scalding hot, but the 2 big rad
hoses are hardly warm.

Thanks
Tom
