What do you mean by play? Does it feel too easy to spin or does it wobble? If it wobbles, get it checked immediately. A wobbly fan quickly develops an appetite for radiators. And we're talking of an early 603 here.

Contact member ke6dcj (Neil) and ask what electric fan he used when he dropped a C36 engine in his 300TE. I think he replaced the front fan, not the clutch fan, though.
