How do you replace the serpentine belt in 1997 sunfire
Near the top of the belt there is a belt tensioner; it has a pulley attached to it. It is spring loaded and there is a provision to attach a breaker bar to force back the spring; once you do, it is easy to remove the serpentine belt.
To remove the accessory drive belt or the serpentine belt from the motor on a 1989 Sunbird, it is necessary to loosen the belt tensioner. Look for a pulley that has a bolt in a slot. Loosen the bolt and move the tensioner so there is a gap in the belt. Then remove the belt from each pulley.
