removing a fan/viscous unit..

<< < (2/3) > >>

richo:
Yes left hand thats what i ment as as normal with most nuts and bolts

extreme90:
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

Range Rover Blues:
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.

age:
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

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