Until I was confident that engine would not overheat, I carried viscous fan in boot, just in case, now hub lives in garage.


(I did a 200 mile around trip with five adults plus luggage as well, still ran ok )

I might give this a try and at least tomorrow can work as a test day for it...

Iirc the electric fan was just to cool the ac comdensor when required butay be wrong.

This removal and replacement was always touted as being an mpg improver as its always wasting power where as electric only works when needed... FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Strangely mine is now working again!!

Still think i'll remove it though, if it helps mpg and stops the engine working so hard as well

Thanks everyone for the advice  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

These paragraphs are taken from RAVE, the second one explains that the electric fan can cool down engine if it gets to hot.

Cheers RichL gives me extra confidence in the system working

I wonder if the viscous unit is for offload use as well, ie low speed and incase the rad gets caked in mud maybe??? FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Ah, it sounds like the TD6 is a lot like the 300TDi.
The 300TDi happily runs without its viscous fan.
These diesel Land Rovers are thermally efficient which I suppose is why LR fitted the FBH to all TD6.

RichL did yours sound like a Boeing 737 on take off, mine sounds like this at low speed till the engine passes approx. 2000rpm after that the noise disappears. Most noticeable from cold.
No sneaking away in my TD6.

Mine was doing that Adrian until it self healed!! possibly due to the threat of removal

Scarey at about 4k rpm though as even at motorway speeds other cars could still hear it  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Needle stays a rock steady middle of the gauge.

Ive often thought about removing mine as it drives me mad (noise) but im unsure weather the electric fan comes in when it gets very hot (like on a disco 2) anyone know?

To be honest, if you're not reaching running temp, it's more likely that the thermostat is stuck open . I fannied about with radiator muffs and stuff like this discussion on an old 300tdi which still never made normal temp. Bothered to take the time to change the stat and it ran upto full temp even in the coldest weather. V8 or else ...

I changed both EGR and main thermostat on mine fisha, after having over cooling problems (Details on another thread) So when I put it all back togeather decided to see if it would run with no fan.

The SC doesn't have an additional electric fan.......it has quite an advanced viscous fan that is also controlled by the ECU, good description of operation on Topix

Mine does have an electric fan... In front of the rad... Strange...

Is it easy to remove the Viscous fan, or do you need to remove the radiator etc? Tom

Release the scrivets holding the fan shroud to the radiator, 2 at the top and 1 at the bottom. Lift the shroud up 3/4 inch to clear the holding brackets and slide the shroud back towards the engine as far as you can. With 2 fan spanners release the l/h thread fan viscous nut and spin the fan off.
Simple as that.

No viscous fan, 21c last week, and still half way up the temp gauge.

Engine sounds quieter (as in large fan drawing in air) and meatier (as in you hear 6 cyl grumble) and maybe even an improvement in MPG

Nice one Ahebron, I will try it out. Tom
