You will need a two or three jaw puller.And it would be a good idea
to place a peice of metal behind the pulley and in front of the jaws
of the puller .To spead out the load ,so as to not bend the blower
pulley. If you plan to reuse the STD pulley at a later date.
Remove the nut before you take the blower belt off.
Put anti-seize on the blower shaft be fore you install the 10% pulley.
And you cannot floor the car after install try out.
