Need to take it off. How do I get the bolt off? Figure a breaker bar and something else to hold it in place. But how?

you can put a breaker bar on it and crank the motor (pull the ecu fuse so it doesnt fire)

you can use a rattle gun

you can man up and use your guns (arms incase you dont get that)

use an extension on your breaker bar if its needed.

also give the head of the bolt a few taps with a hammar to help it loosen.

if you have a bolt that fits the small hole on the pulley, you can use it to keep it steady.

be careful doing that, if its really tight and you crank on it the bolt will break as they are only an m8.

Got it. I used a chain wrench and a Breaker bar. Bolt came out easy after I loosened the power steering pump belt bracket. Then to take off the pulley, I used a pulley extractor. Easy as cake when u got the right tools
