Do you have the remains of the old belt? That has a part number on it that can be cross-referenced at the local parts store. They can be a bear to get to sometimes and you may have to remove another one if that is behind one in front. They slip up over the fan blade and you do it from the bottom side as a rule. Hope that helps. Please get back to me if you need more input from me here as all follow ups are included in our fee.
