How do you change the pully on the crank shaft

What you need is a puller to put on the pulley and pop it off. Hard part for you will be getting to the pulley because its side mounted. Youl have to Jack it up and remove the wheel and the plastic inner fender cover. Hopefully this will give you a straight shot on the crank. Remove the belt, remove the bolt (you will need a nylon strap or a chain to hold the pully while you remove it) then use your puller to remove the crank pulley. Then put the new one on and torque down the bolt to the recommended spec. You ill need something to hold the pulley while you torque it down. Hope this helped let me know
