Thread: Thermo fan conversion on a d2 td5

I'd love to change the Engine driven fan to an electric as the fuel and power saving was very very noticeable but I'll need some convincing.

Happy Days.

Hi

The biggest 16" Davies Craig fan, and the 17" Kenlowe, both move around 2,000 CFM of air, the Falcon EL fans move about 3,500 CFM.

I would think that if those fans cool a V8 Ford properly, then they would do the Rover V8 no problems

What about a TD5?

Hi Joel

If the TD5 uses the same kind of fan with the same type of airflow as the V8 does, then I can't see it being an issue.

I think a bigger issue is getting the right fan housing to gain maximum airflow.

Not sure about the TD5 radiator, but apparently the D2 and the P8 radiators are an almost perfect fit for the Ford EL fan setup.

We have a experimenter (victim ) with a P38 who managed to pick up a set of Ford fans for 20 bucks from gumtree, so we are awaiting the results of his endeavours

look at the watts on a drive motor.


the dia is one thing but the horses used to turn it is as important.


most of these electric fan cars require that the fan run most of the time..and need air flow on the motor way[hiway].most of my small sedans didn't need a fan above 80 km hour. look at water temps as you tail gate a line of pantec B doubles.


the assist fans you get on A/C units are often 60-180 watts.thes have brushes that are normally rated at 2000 hour. dependant on moisture and voltage noise.i have seen 250 watt motors.


my BF falcon has a single fan with a resister to halve speed. I think its borrowed from Volvo.


so my thoughts--if wrong that on low speed your still using the same amps.
that the alternator needs to recharge.


japanese cars that used variable voltage controllers that will save amps?

Totally dissagree with this, on my last commodore ute the fan only kicked in in heavy traffic congestion[ie waiting at the lights], this is why i went for commodore fans in my 300tdi 110[ea falcon fans wouldnt fit[there still downstairs]], as stated i have a led that comes on when ever the fan s kick in, only in city traffic and not when on the highway.

I've fitted Falcon EL fans to my Disco and Falcon AU fans to my 4.6 Rover V8 sedan. Both controlled with an FK 55 Delta Current Controller that ramps he fan speed up and down depending on the temp of the coolant entering the water pump. A dial on the dash let's me adjust the temp at which the fans first starts to wind up.

Hi

That controller sounds like the mutts nutts
