After servicing the viscous fan a few weeks ago, and putting too much silicone fluid in - mean fan on constantly from cold engine, i looked at it again.
Poured some fluid out of the fan clutch.
Now, fan is off and easy to spin from cold until engine temp needle hit normal running temp (i.e. about 3 miles driving), and the fan clutch stiffens up (not solid) just a fair bit of resistance i.e. only spins about 1/4 turn when flicking it, and you can hear it roar when accelerating in low gears.
its a 3.0 TD engine and I seem to be getting about 23 mpg, Then best i have had is 25mpg before servicing the fan, on a long motorway cruise 65-75mph.
I have noticed a slight loss of power, nothing drastic.
my only concern is that i should only hear the fan 'roar' when the engine temp is getting too high. I doubt taking any more silicone fluid out of clutch will help this, any ideas?
