My fan clutch ejected its viscous fluid. I was wanting an excuse for the Tundra/Tacoma w5000 lb tow package fan clutch. It came in today. Immediate difference over stock when it didnt't leak. My A/C is colder on fresh. Of note, it has cooling fins (heat sink) on the whole body, where as the Supra unit (orange clutch) does not have it on front face.
