1989 964 C4 Alternator belt replacement


Vehicle Information: Year: 1989; Body Type: Coupe; Total Mileage: 75726;

My fan belt warning light came on and I have decided to replace both alternator belts at once. My shop manual suggests using a pulley wrench, which was not in my tool kit when I bought the car. I've noticed that there is a star-shaped hole in the shaft of the idler pulley in front of the 24mm nut. Do you instead have to place a tool inside this hole to gain leverage to loosen the nut? I didn't want to damage anything and wanted advice before starting. Thank you!
