I have looked on all the forums and can not find a place this would be better posted so I believe it should go here.
reading lees thread got me thinking of how the viscous fan really works, and I can not really find the answer.
Ok then what is the correct operation for the viscous clutch fan to work. I watched the you tube vids but they all contradict them selves.
is it supposed to be unstoppable 2 minutes after start up and then after 3000rpm and also at full operating temp? or is it supposed to be able to be stopped on start up and before 3000rpm? struggling to find the correct answer for the bmw viscous fan operation.
