Has anyone had any experience using a 4.5 fan clutch in a 3.5? Car is a W108. I hear it's possible but will just be louder than the 3.5 fan clutch? Will anything change aside from being louder and pushing more air? I'm having a hard time finding a good used Behr fan clutch for a 3.5 and I don't want to spend ~$1000 for a new one from the Classic Center.
