I've got an FJ60 2F in my FJ40, which uses a fan clutch. I'm running my stock radiator and modified an FJ60 shroud to fit the 40 radiator. When the fan clutch turns on it is really, really loud, especially running around 3000 rpms at 65 mph. I've put in 2 brand new Aisin fan clutches in, so I don't think that's the problem. Any help or suggestions would be much appreciated.
Thanks,
Mike
