G'day folks,
My viscous fan is stuffed - it won't freewheel under any conditions, and I was wondering if anyone noticed an increase in power by going to an electric fan. I know that a plastic fan doesn't have the mass of a steel one, but at highway speeds it won't be doing anything except creating a lot of turbulence or wind resistance under the bonnet. It is supposed to freewheel at high speeds unless the engine temperature goes over normal, but it's not doing that.
Has anyone found that they got a bit more power from changing to an electric one? I know it works well with old Land Rovers - the fan on those things sucks about 7-10hp from the motor.
Thanks everyone.
