Paul:

Check out
http://www.gowesty.com/vano_cooling_system.htm
for a good description of the different systems (there's another write
up at vanagain.com, but the site seems to be down?)

As Dennis has said, you can pull the plug off the thermo-switch in the
radiator and using a wire, jump the various holes in different
configurations to get the three speeds (if you have AC) to determine if
the switch or resistor is at fault.

What is the best way to check the switch and/or resistor?  I've  tried searching the archives many times and it always times out for me and comes back with an error page. Any advice appreciated.
