    This time put some anti seize on the thread. It really only has to be a little over finger tight as the engine rotation holds it in place.
    I have never heard of a Viscous unscrewing itself. Broken blades by the score on V belt V8s but no unscrews.

    Use a stilson at 90deg to what you would normally use it to grip the edge of the pulley. Put a small piece if timber into the "U" of the pulley to protect the pulley from the bottom jae of the stilson. I have made a 90deg spanner out of a piece of 50x4mm flat bar. It's been easy ever since.

    There will definitely be anti-seize compound going on when it goes back in. I don't ever want lose 8 hours and 5 knuckles again!
    If it's only meant to be finger tight, then the guy who put this one on must have had fingers like a pound of pork sausages and a grip like a bull mastiff!

    Hey mods (Pedro/abbadonxi) is there room in "The Good Oil" for a thread on viscous removal? Seems like it's a fairly regularly played sport?!

    Man you aussies are tight... I brought a viscous fan spanner from Teng Tools Part no. AT095 - $27.95 including $8 airfrieght from Auckland. I imagine it`d be cheaper in Aus.

    Took me 5 minutes to take the fan on my 280k 300Tdi off...

    No substitute for having the right tool for the job...

    Well, I guess thats why we never got around to adding those extra 2 lines to all our fences then...... not that we're in any hurry to ensure the sheep can't get away....

    Teng make excellent tools...better than SnapOn from my and other workmates experiences. I got payed out initally until the usual 'borrowing in the workshop' happened. Good to see another convert bro!

    For anyone else in future, asides from that suggestion, try a long-handled ring-spanner with a length of pipe over it, lever on it or try a good hard whack with a heavy hammer. If that's proving too hard, get a mate to get a pry-bar over 2 bolt-heads to stabilised, then repeat the process.

    The other trick is to align the long-handled ring-spanner (with length of pipe over it) against the ground (so it doesn't hardly have to move), then give the key a quick flick to turn the engine over...guaranteed to work as a last resort.

    providing your definition of work means tightening it up so tight that you snap the spanner and have to gas axe it off...

    its the Fan we're trying to get off and its set up so that the direction of engine rotation tightens it up which is why some are left hand thread....
