I was wondering how do you tell when the viscous coupling is bad. I have a 98 with 78k miles and was just wondering how I can tell when it is done.
Melissa, on my '89 RRC, it doesn't wobble - but it won't fully engage, either. The previous clutch didn't wobble, too - but it was seized solid and caused engine vibration.RoverChic said:Typically when the Fan begins to wobble/weeble; it is time to change (remove the fan cowl and inspect from there---WATCH THE HANDS).
