It probably doesn't work anymore; they like to be replaced every few
years. The design is that the auxillary water pump is run after the engine
is shut off, if the two-wire thermoswitch on the upper coolant flange is
closed because of high heat. The 1st stage radiator fan comes on at the
same time as the pump.
You can get a new pump for around $120 at best, but it too will likely
stop working or break and spew coolant in a few years. Recently listers
have taken to using a Shogun brand electric coolant pump instead; you'll
find it in the archives under "Shogun."
