cos even with the new thermoswitch i cant seem to get the afterrun pump/radiator fan to come on. guess i'll have to try harder.......

nothing wrong with the switch, no hysteresis, just must be cold in chilly scotland.

also noticed every time you turn engine off, the afterrun pump comes on for about 10secs, no rad fan. i guess this is to move the hot coolant from the turbo to the sensor, to activate it if hot enough etc
