Michael asked, in reference to a belt failure in a Vanagon:

This question will show my aircooled ignorance, but how do the non-water
engines stay cool in such conditions?  Seems like even with circulating
water and lots of fans, things can get touchy... man, without water or
fans, that has to be a real heck of a time...

They manage quite easily, but the heater stops working and you may need a
jump-start :-)
Seriously, the fan is mounted directly to the back end (back of vehicle) of
the crankshaft.  The belt drives the alternator and the blower for the heater
(yes, it's mechanically driven).
