Coolant pump, thermoswitch

[Danny]

Cool, thanks for the help. turns out i was looking at the wrong thermoswitch. anyway back to work for the week, gotta wait to the weekend to mess with it again.    
 
"run a flow check to see if the pump actually moves" - how would i go about to do this? listen with a hose?  thanks
Danny

Yup- everyone who comes from a 10vt notices the 20vt runs the fan much
less frequently.

Do NOT let either contact on the after-run switch contact the engine,
or you will blow a fuse.

Also, the pumps have mag-drive impellers, and attract everything iron
that flows through them (which is why keeping the coolant fresh, not
using the green crap, and flushing the system is important.)  Run a
flow check to make sure the pump actually moves.  You might be able to
rescue one with CLR, or by cracking open the housing...but you'd have
to do a really, really good job of cleaning the plastic and epoxying
it back together.
