Any tricks to make this easy?? i.e ways to stop engine turning as undo her??
cheers!

 

What car would help, assume it's a manual, normal trick is put it in gear(top) and use long breaker bar.
On me other halfs astra as it is auto, I use a chain wrench around the pulley to hold that whilst the air gun, or breaker bar does the undoing.

a puller tool is ideal; but as tabs says above, thats another way

 

is it the bolt or the pulley itself that's the problem?

on the bolt i usually set my wrench against the garage floor and turn the engine over on the starter motor, works every time

 

it's a Saab 9000 manual. I was thinking putting it in gear would work. Will have a bash in a minute!

 

put it in gear, that should do it and/or use an air gun.
