Thread: Viscous Fan Information Needed.

some of the early non OEM ones can have and access plug so that you can change the fluid. Ive taken one apart for the hell of it but you'd want to be a bloody good ally welder to get one back together again.

the type shown with the straight bimetal apear to work or be stuffed.
I think the type used on early falcons might be the type that use variable viscocity fluid-becomes thicker with heat-like mitubishi sigma-L300.

--ive tried to adjust the operation temperature without sucsess often you just fill these up and put up with the fan noise..these are match to the job,radiator and fan blade so it its operation is changed it often wont work

refilling..i have had sucsess with some old units drilling a hole in the center of the mounting flange.by experimenting with the fliud type and amount ive been able to get the fan to operate.

a company in newcastle reconditions visco hubs.
bearing issues it has to be a very expencive unit to bother with.

Hey Gav,

please let us know if the new one fixes your problem, mines doing the same, it drives you mad

Can anyone comment on what tyres to fit to my 04 td6 rangie, I am looking for an all terrain or better as I do a lot of dirt road driving. Had a bad run with coopers on my defender so am looking at perhaps Mickey ts or perhaps generals?has Anyone had some real world experience with any brands on these 18in rims in the bush? looking to get into some decent off road driving as well, so a good all rounder is what I'm looking for. Thanks

Will do Neil, but you may have to wait a bit. I've just ordered brakes for it, so my spending for the month is done

Next month it will be due for a service, so it may be a while before I get around to replacing it....

Thanks Gav, im hearing you on the spending, ive had 2 years trouble free but in the last month ive got a list that goes!!!

torque converter
all suspension bushes
tyres
FSR
brakes all round.

cant complain its only wear and tear, done 212,000 and got 70,000 out of my scorpion atr's. things do seem to come at once though.

still loving it !!!

cheers

I don't know much about the working of the viscous, but I do know that they have an anticlockwise thread ( turn clockwise to remove), unlike most other lr engines.

Well, I've had a development on this - instead of the fan being locked up all the time, it is now gone quiet - I am assuming it has failed, and is just free wheeling now, although I haven't checked yet. Maybe the viscous locking up is the first sign that it's about to **** itself completely? Not sure, but I love that it doesn't roar all the time like it used too. I can drive it around with the windows down now

I'll have to keep an eye on the temp though until I get a replacement, but driving around town today the temp gauge didn't move, but it is a tad chilly out...
