Got my parts from cdan. Noticed the new fan clutch is a ton bigger than the old one

Also it doesn't go in the same way. The old one had bolts keeping it on the fan.

The new one has studs.

Anyone know the nut size I'm supposed to be using?
Also, it doesn't appear like I'll be able to reuse the nuts keeping that whole assembly on the water pump

Anyone know the sizes for those?
It looks like you had an aftermarket fan clutch that was installed incorrectly with bolts. They come from the factory with studs.
That's good to know. Now I have the correct one. Got it on today.
Is the new fan clutch a blue hub AISIN clutch?

You are comparing a jicky aftermarket copy to the genuine article.

I love stuff like this because it CLEARLY shows that there IS a difference.
