If your car is having issues with the fan clutch, you may be wondering if it is normal for the fan clutch to wiggle. The answer is that it depends on the type of fan clutch you have. If you have a viscous fan clutch, it should not wiggle at all. If you have a thermal fan clutch, it may wiggle slightly when engaged, but should not move excessively. If your fan clutch is moving more than usual, or if it is making noise, it may be time to replace it.
