thanks, I've started tracking down my coolant problem... it seems that my auxiliary fan does not come on any more (had this problem before, blew a fuse but the fuse is good now). I'm gonna try to see if it's just the switch that's gone, or the fan itself. Anybody know what wires to jump to bypass the switch? It looks to me like it bolts on to the water pump/thermostat housing (#125)
