Hi Guys
First off I'm talking about an Omega 2.5TD the one with the 6 cylinder BMW lump in it.
If standing outside the car looking straight at the windscreen which way do I need to turn the nut in order to remove the viscous fan?
I believe it's a left hand thread, but I'm still not sure if it needs turning anticlockwise or clockwise in order to get the fan off?
Thanks for your help
Clive

Knock it over to the right as you look at it :y
I think ;)

Hello Doctor Gollum
Thanks for the quick reply I'll give that a go tomorrow, I just need to find a way of stopping the water pump from turning at the same time.
-
A block of wood used on a long belt run to load the belt up should suffice.
That said, if the petrol BMW fans are anything to go by, a sharp tap on the fan spanner to shock it should see it almost finger tight :-\
If the water pump pulley is bolted, then a suitable ring spanner on the top right bolt (as you look at it) pointing to the left (as you look at it) push this down as you knock the fan spanner over to the right :y

Yep IIRC. LH thread anyway, and very easy to remove.
-
Definitely left hand thread - it tightens in service due to the clockwise rotation of the engine.
If it's tight, as it usually is, take a large pound-through screwdriver and a decent hammer, place the blade on a peak of the RHS of the nut as you look towards the rear of the car, and whack!
Once it has shifted a little, it will respond to an ordinary socket.
Ahem, lots of experience with my beloved, but now departed Carlton.....

Fixed for a technicality :-*

Left hand thread, but can be on quite tight, and difficult to lock in place. You might need to be creative with locking it,
-
Yes TB, as I said earlier - the Liverpool screwdriver approach!
Refitting won't present a problem because it will "ride up with wear" tighten in service..... :)

Yes removed these on my Carltons and Senator 24v gives a nice boost of power
but when fitting the electric replacement (which I suppose is why your doing it)
don’t forget to make double sure it comes on when needed. Maybe you can use the air con fan if
You want to perhaps.

And if not tight enough, come undone when a hot engine stops ;)
Apparently ::)

In the UK, if not towing, leave the tinker off, not needed on well maintained engine

I was towing with my Carlton and even after replacing the radiator I wasn't happy with the cooling, so I added a Kenlowe aftermarket fan: it fitted just in front of the radiator by means of some feed-through cable tie type clips. The temperature sensor for the fan was a bourdon tube placed into the radiator end of the top hose, driving a thermostat unit to select temperature.
Easy enough even for me to do! :y

I've just noticed I still have a fan for my - now sold - TD hanging in the garage. :-[

I had one of those Kenlowe fans fitted to my Granada. Gearbox was fine when solo but overheated with the tin tent on. Used to leave a smokescreen behind me. The kenlowe fixed all that.
