A 2000 reg V6 originally had the 3-speed system. Yours seems to be still in working order. Here are the set points for when the fan is tripped by the coolant temperature.
96 -100°C = Low
102 -106°C = Medium
108 - 112°C = High
Equally important is that the slow speed runs continuously when the aircon system is operating, even if the coolant is below 96°C.
I think you have no issues with the coolant circulation, but double check that the V between the heads is free of coolant puddles or pink stains. These engines tend to suffer coolant loss from the plastic housing containing the thermostat.
