A taurus with bad bushing will spin when it shouldn't. Nevertheless oil leakage is like a redwood post driven through the heart of a vampire. It's the utter, absolute and bitter end, period.
In a wrecking yard pick a fan clutch with (if anything) only dust on the hub. Not even oil film from weepage is allowed. Take your old fan along to match mounting holes. Pay attention to overall length and length from hub to fan bolting surface.
Don't listen to unfounded rumor.
The OEM units are as good as they get.
Many aftermarket super fans are far lighter than their OEM cousins. This is a blessing as weight contributes greatly to aluminum hub flexing and premature seal failure. Get the most aggressive fan you can find, then compare the weight. GM went cheap and used heavy steel. There is nothing wrong with aluminum blade paddles.
I just pureéd my minced words.
