Hi all,
Ive diaganosed my over heating problem as a failed viscous unit but now i need to take it off, ive got a 32 mm spanner for the nut on the end but i was wondering how to stop the unit turning..
any ideas?
-
stick a big allen key, drill, screwdriver, bit of bar or whatever in one of the holes in the pulley to stop the whole lot turning when undoing the coupling
-
Are they reverse thread???

Are they reverse thread???
Yes, left hand thread
-
No they are not as iv'e just had mine off [td5].My mate told me to give the spanner a light tap first with a hammer.
They do seize up sometimes.
I jammed a big screw driver between the nut and levered it down againsted the screws on the pully wheel.
-
Yes left hand thats what i ment as as normal with most nuts and bolts
-
all tdis are left hand thread so need turning clockwise to undo
td5 engines are normal right hand thread so need undoing anticlockwise
i never bother locking them off, a quick blow with a 2lb lump hammer shocks them undone
-
The serpentine V8 is RH thread, all other 8s and TDi are LH thread. I don't know about TD5. I do know that the RH thread viscous fans have a smaller nut. If it spins when you tap it with a ahmmer than try tightening the belt with a clamp or large mole grip.

TD5 is normal 'undo anticlockwise'.
Shock with lump hammer worked for me. Take out one of the pulley bolts to get a swing with the spanner.
Do remember not to lie the new unit down flat - must stand upright or the viscous lock won't work. A

I did not know that, they are supposed to be self-priming once fitted :-k

thats a worry, i had my mine delivered..i hope the courier knew this aswell! lol

I was told this for 'storing' mine for nearly a month while I was doing the head in my spare time - I'd guess lying down on the delivery run would be acceptable!! :D A
