Very nice educational video. Tqsm for sharing this informations. As a woman and a layman, I totally understood the differences and to correctly install the correct alternator pulley as per car OEMs installed. But, sometimes dealing with men and local mechanic who don't really care, they think we woman demand too much and a hustle to them. Cause in their knowledge there's no difference and can use any types of alternator pulley and most resort tu the fix types one for easy work done.
