is that you will damage your radiator = $$$ . The water pump is usually the culprit when fan is wobbling. I had a fan that was cracking that did not wobble ( I did replace it immediately). To my knowlecge, the clutch just doesn't fail that way... I'd take it apart and inspect the parts.... Buy only Nissan parts, or suitable substitutes from a Z store: Coz, for instance. If you replace with local parts store parts, you really dont' know you've elimated that part as the problem.
