Help! I am attempting to remove and replace a noisy serpentine belt tensioner pulley. Is the pulley bolt right-hand thread? Must I remove the entire pulley assembly (spring housing / arm and casting) and use an impact wrench. I am unable to budge the pulley bolt w/ normal wrench pressure...and before I break something, I'm asking what the tricks of the trade are for R & Ring the pulley. Thanks for any input.
