Hi guys, seen a video the other day on how to check the viscos fan is working correctly. When I went to run the test on my GQ turn out its not cause one of the previous owners have jammed the fan through drilling it and putting screws through it, so now it does not spin on the shaft at all. So whatever the speed the shaft is turning at, the fan is turning at to. I really do not see why they just didn't replace the viscos if there was an issue with it, or is there a good reason why this person has done this?
