VISCOSE FAN

[smith335]

i want to change the fan on my 2.3 petrol 90.
its the old fixed four blade fan.
i want to change it to a viscose unit.

now does any one know how this is done?
is it straight forward, ie just get a viscose unit and fan and a different spacer/adapter.and bolt it on the the pulley.
or would one have to change the water pump?

not sure how these things fit.

any help and advise would be great.

Why not go electric with a thermal switch in line?

I think the water pump is different. If I understand it correctly, the 4 blade fan bolts on using the 4 pulley retaining screws. The viscous unit uses a large thread in the middle which is part of the pump shaft.

Well, at least, I think it's like that! Someone else will no doubt be able to confirm that.

thanks for the info guys, i think it does fix to the water pump.
so thats rules that out.
may go down the kenlowe path but do they realy make any difference?
they cost a bit,and if its only saving a bit then is it worth it?

i am never going to make a 2.25 90  good on fuel.
o dear, what shall i do..........

Try going to a scrap yard, I went the other day and got a pair of fans in one shroud out of a v8 Audi for a tenner.
The fit straight in my V8 Defender, got meself a adjustable thermostat off ebay and hey presto a complete set up for £30.
Works a treat, ran them through a double over-ride switch so I can kill one or both fans for fording.
I havent tried them on a motorway run after a day playing in the mud (blocked radiator type senario) but so far things seem to be ok.
Warms up alot quicker, and I have set the thermostat to come in half way up the temp gauge, where the viscous wouldnt let it go any higher than quarter in this weather.

When I bought my 2.5 petrol 90 a few years ago, it had already had the fixed fan removed and a Kenlowe fitted. On normal road use it was fine, however, when green laning and off road the  Kenlowe wasn't up to the job, so I refitted a fixed fan and it was fine there after.

I have now changed the engine to a 200Tdi from a Discovery and this time removed the viscous fan and replaced it with a pair of fans from a 2 litre Mondeo. On the road the temp sits at 82c constant, when off road it creeps up to around 90c, then the thermostat (from the old Kenlowe fan) cuts the Mondeo fans in and drops it down to 82c again.

I picked up the Mondeo fans on ebay for a fiver.

I have a Kenlowe kit fitted to my 1992 200Tdi Disco. Works great, and warms the engine up quicker too.

As has been said before, any twin fan kit would fit with the right mod. I think the peugeot twin fans are quite popular. All you need then is a Thermostatic switch. Should be easy to get. Having a switched overide would be a good idea too.

thanks for the tips,
i think i might just stick with the fixed fan ...
i least i know it will keep the engine cool!!!

cheers

On the scrap yard front I fitted an old Mondeo twin fan via a Kenlowe switch, the fan was a perfect fit :D
Never had any problems with heat and I only run one of the fans at the mo (even through the summer traffic), couldn't find the time to visit ford for the relay to run the twin............ :oops:
