Electric Fan

[4tuna]

Hi Gents,

Trust you are all well on this hot monday morning,

My question today is if i remove the current fan, and replace it with an electrical fan, will this help a bit with the consumption?

Or will it overheat?

Rather Leave the std viscous fan .

Much safer .

Agreed you may save fuel but no more than a km or 2 on a tank

The resistance / drag on a motor caused from driving a fan is considerably more than one would imagine. If it were not, why would automotive developers have gone to the lengths of engineering the visco-fan, and similarly why would the manufacturers increase the production costs by including such fans. Why also was the idea of electric fans introduced, particularly with 'performance' vehicles. In motor sport circles it's not uncommon to change over to electric fans and dispense with the alternator ... a fully charged battery will last more than long enough for a track meeting when all it's driving is an electric fan, motor ignition / electricals and instrument panel.

IMO it will give you considerably more than a few extra kilos per tank, especially with smaller capacity motors that 'feel' the drag of a fan more than the bigger ones. So the question "is it worth the effort and cost" becomes a bigger consideration if you're running a 3 lit capacity motor, for example.

You would have to supply and install the fan, a relay and a thermal switch on the rad which controls the fan operation. The switch would also have to be 'calibrated' to suit the motor's operating temp. All this would need to be installed on a dedicated circuit with it's own fuse. (These costs would need a fair amount of fuel saving to off-set.)

Also to be considered is the long term reliability of another electrical device which is critical to the running of the vehicle. Imagine that it lets you down on a trip to Nam or Moz ... you're effectively stranded until you can get a replacement if at all available in the area you find yourself.

Personally I would rather stick with the visco-fan for peace of mind and accept the extra k/lit in favour of reliability, unless the vehicle is intended as a city based run-about.

Thanks guys for all the answers,

Was just a thought, will keep it as is, :)
