Thread: thermo fans

I have successfully modified Nissan pintara fans. (Ford Corsair) They fit with a minimum of trimming and require 2 right angle brackets to bolt on to the Rangie shroud mounts.
The complete shroud with 2 fans can be picked up at a wreckers for less than $50.
I can post pics if needed

that would be great if you can just to give me some direction . are they ok ? i mean no cooling issues that sort of thing , The 3.9 should get some slight gains with electric fan and i do mean slight , did you find this

Ford EL AU seem to fit nicly.

pump huge amounts of air.

come fitted to a shroud that is easy to fit to RR rad,

I doubt you'll see any gains in power or better fuel economy with electric fans. The advantage is you can switch them on or off when you choose too ie: when crossing a river.

Go for Ford EL-AU thermo fans. As HSVRangie said they work very well and fit easily to Rangie/Disco radiators. You wont have any issues keeping the motor cool with these fans.

Get a thermo switch from an auto elec, one 60amp relay or two 30 amp relay's and a switch and light for the dash + some high amperage wire and spade fittings etc etc.

There should be (usually is) a wiring diagram in the instructions with the thermo switch to help you wire it all up.


Hope this helps.

There hav'nt been any cooling issues, (never gets past 1/3 of the gauge) I run them from a Magna temp senser mounted inline on the top Radiator hose. For normal driving they only come on when stopped in traffic.
I chose the Pintara fans because they clear the water pump shaft by a country mile, the Au fans sit a bit closer, pump more air and cost more.
I will post a pic tomorrow

thanks for the imput . a mate has a v8 au that he is wrecking . ill see if he has the fans ?

I did a conversion using 2 large Repco fans a couple of years ago after my 3.5 EFI mechanical fan threw a blade. I photographed each stage of the conversion and can e-mail them if you like. It was a relatively easy job and the fans cover almost the whole radiator. I've started to make a controller that has 3 set-points and will progressively bring in fans as the temperature rises. (1st the 2 aircon booster fans in front, then each of the new fans in turn).
