    I need to align fan and idle pulleys. How to move the fan. Two bolts on fan hub are removed and was trying to drive flat screwdriver in to the hub to widen it. Can't slide it.
    Bet some Volvo engineers were employed to design such crap.

    It's likely seized and they can be tough to free up.Try adjusting the pulley on the jackshaft instead.It's in a easier spot to get at.If it's seized you might have to remove the jackshaft and do it on the bench.Heat it with a torch and put some oil on it but be careful driving a screwdriver into the hub as it will crack if too much pressure is put on it.Best to use a puller if you have one available.
